Gompertz 1821

Postby Lock » Sun Jan 08, 2012 7:17 pm

From a history of the RSPCA (Royal Society for the Prevention of Cruelty to Animals), here:
http://thevictorianist.blogspot.com/2011/06/abuse-of-our-powers-over-animals-or.html
During Reverend Broome’s incarceration, Lewis Gompertz had temporarily taken over as the Honorary Secretary of the Society, a role which he remained in after Reverend Broome was released.
Lewis Gompertz was somewhat of an eccentric man. He was an inventor (aren’t the eccentrics’ always?) and always maintained that he would do nothing in his life to cause suffering to animals. This belief was such that not only was he a vegetarian, but also refused to ride in coaches because he believed that pulling coaches and carts caused suffering to horses and donkeys. To alleviate the need for such quadruped power for transport, in 1821 he came up with his most notable design; a hand-crank to be applied to a small cart which the driver used to propel his vehicle, thus removing the requirement for a horse or donkey to pull it. He applied the hand-crank design to Baron von Drais’ bicycle design, and came up with the vehicle below.

An Addition to the Velocipede. By Mr. Lewis Gompertz, of the Oval, Kennington, Surrey.

With an Engraving.

Fig. 4 (Plate III.) is a representation of that ingenious and well-known invention, the velocipede, of Baron Von Dray, with my addition to it for increasing its speed, or of lessening the labour of the rider, the velocipede being slightly altered and adapted to the addition, and the chief object of which is to bring the arms of the rider into action, in assistance to his legs, and consists in the application of a handle C, which is to be worked backwards and forwards, to which is attached a circular rack D G, which works in a pinion E, with a ratch-wheel on the front wheel of the velocipede, and which, on being pulled by the rider with both hands, propels the machine forwards, and when thrust from him (in order to repeat the stroke) does not send it back again, on account of the ratch which allows the pinion to turn in that direction free of the wheel; H is the saddle, and the rest B requires to be different to the original of Baron Von Dray, as shewn, and is made so that the breast of the rider bears against the front of it, while the sides come partly round him at some distance below his arms, and is stuffed with something soft, and by means of this he can balance the machine without any exertion of his arms, which are employed in giving motion to the velocipede, in conjuncion with his legs, and also of guiding it, as the front wheel swings in the same way that it does in the original, and the same handle that works it forward also guides it. The rider may, if he choose, keep his arms and the handle at rest without causing the machine to stop, or he can keep the velocipede in motion by means of it, without using his legs if the ground be good, and if he can balance himself.

The circular rack must be a sufficient portion of a circle to admit of a full contraction of the arms of the rider, and of nearly a full extension likewise but not quite, because when the velocipede goes backwards the rack must be kept still beyond the pinion, in which case the arms are extended rather more than when they are in motion, and were this not attended to, the handle would be drawn out of the reach of the rider. The wheels were larger in the velocipede to which the drawing refers than they commonly are, and if they should be smaller than represented, the pinion should also be smaller to correspond to it, or the circular rack larger, so that one stroke of the handle will move the machine the same distance as when made like this, which from experience has seemed best to me; the determination of this point is important, and if the motion of the handle were to be much quicker it would become but of little advantage. The back or beam of the velocipede was made of beech strengthened underneath with iron, the parts where the wheels go were of iron, and the upright parts of the handle, though of steel, were rather too slight. This velocipede requires to be rather stronger and heavier than when they have not got the hand motion; but I have found the speed of them to be greatly increased by this addition, and though there is more exertion of the arms required to work the handle in the one, than to lean on the rest with them in the other, it is not such a continual stress; the action of the arms then resembles that of rowing, but less tiresome to the hands, which have only the force of the arms to resist, whereas in rowing they must first resist the muscles which draw back the trunk or spine on the os femoris, with the weight of the body added to it, and afterwards the force of the arms themselves.

It is worthy of observation, how much delighted the public were with the velocipede on its first appearance, and how soon it was thrown aside as a useless toy; the fault, however, seems not to be in the invention, but in the manner in which it has been received by those persons whose patronage they required, and by those also whose injudicious criticism they did not require, and chiefly owing to their having been prohibited the use of the footpaths, which, if necessary in some places, should have been accompanied with an Act for allowing them three or four feet of the width of the roads for their sole use, and for that to be kept in very good repair; this they deserve, and persons then while using them would not be exposed to danger where there are many carriages and horses, nor be obliged to wade through mud; and it is only by this being adopted that mankind would reap the advantage from machines for this purpose, of being converted from one of the slowest animals in the creation, to one of great continued speed from his own salubrious exertions; the ridicule then with which they have been assailed by some of the idle and the caricaturists, if of any importance, must yield to the advantages which they will bestow on the world.


Thanks Lewis!

Experimental tricycle - Wrought iron and ash framed 'Experiment' tricycle with large wheel at the rear and two smaller wheels at the front. Steering handle on off side of seat and rear wheel brake handle to near side of seat. Signed 'Morley Fec Haddiscoe' from Norfolk. Swinging wooden foot pedals fitted to iron frame are connected by cords. 'The three-wheeled freewheeling velocipede called the 'Experiment' was made in 1840 by Morley of Haddiscoe in Norfolk, said to be the son of a vicar. It is a remarkable piece of ingenuity but probably no more efficient for being so. The pedals are connected by cords to spiral pulleys on the single wheel, these pulleys are connected by ratchets to the hub and are returned by spring-loaded recoil wheels above the pulleys. The pulleys are quite separate from each other so that the pedals could be used independantly and by adjusting the length of the drive cords a form of variable speed was achieved. The front axle is steered by a handle on the off side operating cords in a manner reminiscent of that used on traction engines. (M. Jessup). 'Out in the Norfolk Marshes near St Olaves stood a unique tricycle. The Experiment of about 1839, the first known machine with free-wheeling capacity.' (CPW quoted by M. Jessup).

Scooters: Size Doesn’t Always Matter

Postby Lock » Mon Jan 09, 2012 12:26 am

http://www.petersen.org/default.cfm?docid=1082
Image
Scooters have captured the attention of motorists throughout the world. In addition to their quirky and often endearing styling, the diminutive two-wheelers are affordable, maneuverable, extremely economical to operate, simple to park or store, and often easier to license and register than cars or motorcycles. Thanks to their mechanical simplicity and wide availability, scooters have long played a vital role in the pursuit of personal mobility throughout the world. Not surprisingly, they outsell automobiles in many areas and are even a preferred means of family transportation in places like India, Pakistan, China, and elsewhere. In the United States scooters are becoming increasingly popular as gas prices continue to rise and the motoring public seeks a new way to proclaim their individuality and personal style on a budget.
Image
The earliest precursor to both scooters and motorcycles was the 1894 Hildebrand and Wolfmuller, the first motorized two-wheel vehicle sold commercially. Yet while the primitive vehicle used a scooter-style step-through frame design, it did not directly influence the evolution of most two-wheeled vehicles other than to demonstrate that a two-wheel layout was viable and that there was a potential market for vehicles configured as such. Instead, motorcycles evolved directly from bicycles and shared their large wheels, vertical frames, and saddle-like seats. In contrast, scooters evolved from the kick-push children’s toys with which they shared their name. These vehicles had a single small diameter wheel at each end of a platform about the size of a large skateboard upon which the rider stood. A pole extended upward from the front wheel to the handlebars for directional control. Ultimately, the word “motor” was added ahead of the word “scooter” to distinguish them from their unpowered counterparts. Today a motor scooter is normally defined as a small two-wheeled vehicle with small wheels, a small engine, a step-through frame, and a platform upon which a rider can rest his or her feet.

From the beginning, no vehicle has been simpler to operate or easier to get onto than a scooter and they did not require a great deal of gear and specialized apparel to wear while operating. Motor scooters could be driven in places too small for even motorcycles and were much cheaper to buy and operate than automobiles. The step-through frame and foot platform meant that all a rider had to do to mount a scooter was take one small step up, turn to face forward, and sit down. It was not necessary to throw one’s leg over a high mounted frame member or gas tank, a maneuver that women during the early years of powered transportation would have found impossible to execute because of their long dresses and untold layers of bulky undergarments. Like most consumer goods that embodied newly introduced technologies, scooters were purchased primarily by wealthy motorists to use as local runabouts when they were first marketed during the 1910s.

Image

The American 1915 Autoped is regarded by most historians as the first true scooter. Looking little different than the child’s toy to which it was so closely related, the New York-built Autoped was powered by a tiny 1.5-horspower, one-cylinder motor attached to the left side of the front wheel. To accelerate, one simply had to push the handlebar stalk forward while pulling it back slowed the engine and engaged the brake. The fact that a brake was fitted to the front wheel only was a minor concern because of their severely limited performance; top speed on level ground was just 18 miles per hour. Autopeds appealed to early buyers because they were nimble, easy to maneuver, and easy to mount. They were also easy to store and, because the handlebars could be folded down, it was theoretically possible to carry the device with one hand like a suitcase. Though primitive compared to later scooters, the Autoped was as cutting edge during the 1910s as the Segue is today. It would have been difficult for observers not to be amazed as the new conveyance buzzed past them and down the road, usually with a smug, well-dressed rider aboard. They were greatly admired abroad and Krupp made them under license in Germany from 1919 to 1922. Like electric cars, Autopeds were heavily promoted to women because they could ride them while wearing regular street clothes, including large hats and the long dresses that were then in fashion, and their limited range and poor performance was not an issue.

The large majority of early motor scooter buyers lived in cities with smooth paved streets that did not have the bumps or deep ruts in which very small wheels could get caught and possibly cause injury to the rider or damage to the machinery. That scooters were significantly less powerful, far slower, and more delicate than the average full-size car or motorcycle was actually appealing to women of the day, most of who would have found themselves intimidated by anything larger or more massive and unwieldy. Eventually the tiny platforms sprouted seats for greater comfort (and marketability) and horns and lights for safety in traffic and night riding. Despite the obvious advantages, scooters did not become popular during the 1920s in part because most people lived in neighborhoods where they had easy access to employment, shopping, and businesses, and an integrated public transportation systems to take them where they needed to go. For the vast majority of the population, a scooter—or any other means of personal transportation—would have been superfluous.

English entrepreneurs spearheaded a resurgence in scooter manufacturing for a brief period after World War I as a large number of thrm entered the scooter building business in an effort to utilize some of the excess production capacity that had been created for the construction of weapons of war. Electric lighting, new suspension systems, and multiple speed gear boxes were soon incorporated into scooter designs. Yet while the little vehicles evolved rapidly, the placement of their engines would not be standardized for several years. While early scooters like the Autoped had engines that attached directly to the front wheel, later models from other manufacturers (like the 1917 Kenilworth) had engines mounted low and ahead of the rider’s feet and others (such as the 1919 ABC Scootamota) were designed with their tiny engines immediately above the rear wheel. One American manufacturer, Briggs & Stratton, built theirs with the single-cylinder engine attached directly to the side of the rear wheel, a placement that simplified the drive system although it added significantly to unsprung weight and affected stability and ride quality.

Image

By the early 1920s, virtually all scooters were equipped with seats and an ever increasing number were designed with engines located under the rider, an area that would otherwise have gone unused. Such an engine placement allowed for a low center of gravity and permitted stylists to create attractive metal bodywork that served as both a covering for the engine and a support for the seat. Some progressive designers eventually extended this sheet metal shroud forward at the bottom to form the foot platform and splash guard. A few manufacturers took styling more seriously than others and one unusually advanced design, the British 1920 Unibus, was so well integrated that it could easily be mistaken for a 1950s German model. As it did with automobiles, the overall appearance of scooters slowly progressed from a collection of disparate, unattractive parts to a unified, neatly packaged whole. Unfortunately, the reputation of most early scooters was damaged by an overabundance of bad handling, poorly designed, and weakly constructed examples that had been rushed to market to take advantage of the then current fad. And while a small number of quality manufacturers continued their pioneering efforts, their models were too expensive to compete and during the mid-1920s scooters all but disappeared from the market for the second time.

The world wide lull in scooter production continued until almost the end of the Great Depression, when a newly emerging class of American motorists created a fresh demand for the blend of distinction, utility, and enjoyment that scooters offered. During this period, domestic manufacturers rose to the forefront of motor scooter design and innovation, and a large number of scooter builders were established in the Midwest and California. One of the first scooters to rise to national prominence was the Salsbury, brainchild of minimalist transport pioneer E. Foster Salsbury. Working first in the back room of his brother’s heating and plumbing shop in Oakland, California before relocating to Los Angeles, Salsbury was reportedly inspired to create his first scooter when he noticed famed aviatrix Amelia Earhart riding one of the few remaining operational Autopeds around the Lockheed Airport in Burbank. But whereas the Autoped of the mid-1910s was intended as a plaything for the affluent, Salsbury scooters of the mid-1930s were intended to mobilize the masses by offering inexpensive, reliable transportation for average people to take to the increasing number of places that were too far to walk, but too close to drive.

Breaking with American scooter tradition, Salsbury equipped their first scooter, the 1935 Motor Glide, with a seat for the rider. It also had an exposed engine with a primitive roller drive system that easily lost grip on wet surfaces. Predictably, very few were manufactured before it was replaced with a model having direct drive and a seat mounted on an attractively designed metal shroud that surrounded the engine. By 1937 Salsbury was building what looked like a bar stool on wheels equipped with a continuously variable transmission, the first ever on a scooter. Foster Salsbury’s early success inspired other manufacturers to join the fray and the Salsbury Motor Glide was soon sharing the market with scooters manufactured by Powell (Pomona, California), Moto-Scoot (Chicago, Illinois), Cushman (Lincoln, Nebraska), and dozens of others. Included among these manufacturers, though often absent from formal listings, were those that offered assemble-it-yourself models like the Renmor Constructa-Scoot, which could be purchased with or without an engine. Catering to the lowest end of the market, some scooter designers offered only plans for sale to those who were (or thought they were) handy enough to build a scooter from scratch using their own parts, although it is extremely unlikely that many did despite their good intentions. By the late 1930s, aficionados came to consider scooters as important as clothes and jewelry in proclaiming their status and very few wanted to be seen riding on anything that looked rickety or homemade.

Image

Advertisements and articles in magazines such as Popular Mechanics helped to propagate the excitement surrounding scooters among adults even as they whetted the appetites of early adolescents anxious to experience the thrill of operating a motorized vehicle that seemed to be sized just for them. Many photographs showed attractive women riding scooters (often Salsburys) in the California sunshine or employing them as mechanical ponies for games of parking lot polo. Hollywood actors and actresses contributed to scooter popularity—and glamour—by being photographed on them as they clowned for the camera or by using them to traverse expansive movie studio lots. And like Amelia Earhart did with her Autoped, airplane pilots and airport workers across the United States began to use scooters to cover large stretches of tarmac, which they were often obliged to do. This utility was later appreciated by World War II pilots, ground crews, and messengers, most of who were spared having to walk the long, tiring distances to, from, and between airplane hangars, offices, mess halls, barracks, and the aircraft.

During World War II, some specially designed motor scooters took flight so that they could be airlifted behind enemy lines and dropped by parachute with Army Airborne troops who then used them for basic ground transportation when they landed. Sometimes called parascooters, they were built by companies such as Cushman in America, Welbike in Great Britain, and Volugrafo in Italy. Other scooters were deployed on the ground, serving as tiny troop movers, supply vehicles, and weapons carriers. But whatever the use, they were usually stripped of all comfort and convenience amenities, equipped with heavy duty tires and other components, and painted the preferred color of their country’s military. Having developed a basic kind of automatic transmission of its own, Cushman eventually replaced Salsbury as the dominant American scooter manufacturer, building as many as 300 units per day for use by both military personnel and civilians who found it virtually impossible to get around any other way during the days of gas rationing, tire shortages, and other limitations related to private transportation.

Motor scooter sales boomed after World War II and large numbers were built all over the world, though the reasons for their popularity varied from country to country and region to region. In America, the pent up demand for anything motorized created a sellers’ market for all forms of personal transportation and after the armistice a considerable number of newly established manufacturers invested the money they earned during the conflict into the business of building vehicles of all kinds. Like their counterparts in the automobile industry, these new scooter manufacturers seized what they believed was the ideal opportunity to launch a new high-demand consumer product. Anticipating a brisk market, some companies, including jukebox manufacturer Rock-Ola, diversified into scooter building. Regrettably, most new motor scooter manufacturers misread the market and the transportation revolution they were planning for did not materialize. As the American economy grew beyond all expectations, the very large majority of domestic motorists developed a taste for ever more advanced styling and engineering along with a desire to display their increasing affluence. For them, scooter ownership was not compatible with these new priorities and demand plummeted. Even the space age look of the swoopy Salsbury Model 85 could not save it and by 1948 the firm that had pioneered scooter design and manufacturing was unceremoniously forced out of business.

Overseas, the economy of most countries after the war was shattered and the mood was somber. Whether Allied or Axis, the warring nations had to deal with a decimated manufacturing infrastructure, a scarcity of raw materials, and, for some, new rules about what they could and could not produce. In Germany, Italy, and Japan, military aircraft manufacturers like Heinkel, Piaggio, and Mitsubishi were prohibited from building aircraft or anything else with the potential to be used as a weapon of war. Desperate to remain in the manufacturing business, a number of these firms turned to building motor scooters, unwittingly creating some of the most iconic vehicles of all time. The designers derived their inspiration from a variety of sources and embodied in their products the kind of progressive, yet rational styling that American scooters had always lacked. Foremost among them, the Italian Vespa was introduced in 1946 by Piaggio, a firm that built airplane engines during the war, but needed a low cost product with mass appeal to remain viable in the postwar environment. Their now legendary motor scooters helped put Italy back on wheels and by 1949 Italian roads were buzzing with an estimated 110,000 of the tiny vehicles, a large proportion of them Vespas. Thanks in part to the Italian government aid also enjoyed by Vespa, Ferdinando Innocenti was able to introduce his Lambretta in 1947, setting the stage for their now famous rivalry with Vespa.

Image

American investment aided in the rebuilding of the German manufacturing industry and motor scooters were an important contributor to the reindustrialization of the nation. A number of scooter manufacturing operations were established by firms that were not allowed to return to building war materiel such as Heinkel (a former aircraft manufacturer) and Simson (a former firearms manufacturer). Their products, like those of most other German scooter manufacturers, were large, heavy, and fast. And while such qualities made them ideal for travelling long distances on long, straight autobahns, they were incompatible with the needs of motorists from other European nations forced to contend with cobblestone city streets and twisty country lanes. A relatively small number were sold outside of Germany as a result. French companies also produced scooters that were little known outside their native land as did British scooter manufacturers, who tailored their products too specifically for the conservative home market to be appealing to international buyers. Operating in near isolation, Eastern European motor scooter manufacturers found themselves building the only type of vehicles that the majority of citizens in their home markets could afford, many of which came to embody the Western design excesses they supposedly disapproved of.

As in Germany and Italy, Japanese industry was not permitted by the occupying forces to manufacture any product that could potentially be used as a weapon of war and many former airplane and armament manufacturers turned to building scooters. Fuji Sangyo, an offshoot of the defunct Nakajima Aircraft Company (builders of bombers, fighters, and interceptors during the war), was reborn as Fuji Heavy Industries and began building Fuji Rabbit scooters in 1946. These scooters used a number of surplus aircraft parts, including the tail wheel of a bomber that had been re-purposed as the front wheel of the scooter. Mitsubishi (manufacturers of the legendary Zero fighter plane) introduced their first scooter, the Silver Pigeon, also in 1946. Both firms’ designs borrowed heavily from those of the Powell and Salsbury scooters that had been brought to Japan by United States military personnel, giving them an unexpected, but strong California connection. Fuji and Mitsubishi scooter production continued into the 1960s with a large proportion of their early production going to their insatiable home market, a situation that temporarily allowed European and American manufacturers the chance to operate without significant competition from the East.

Image

When their home market became saturated, Japanese manufacturers expanded their reach to include North America, with disastrous consequences to the few remaining domestic scooter manufacturers. Period advertisements accurately portrayed Japanese scooters as the fun, friendly and reliable vehicles that they were and attracted the attention of a market segment not normally associated with scooter ownership. Even Vespa could not compete against the low cost, high quality products from Honda, Yamaha, and Suzuki, and withdrew from the American market in 1979. Having added mini bikes and mopeds to their product mixes over time, manufacturers from Japan enjoyed great success in the United States, but could not possibly have predicted the wave of nostalgia that would sweep North America during the last decade of the twentieth century. Just as cars of the 1950s and 1960s have recaptured the imaginations of American motorists of all ages, so have scooters. Fond desires for the trappings of a bygone era coupled with unpredictable fuel prices, concerns for the environment, and an enduring desire to look as stylish as possible regardless of prevailing circumstances, have created a brisk demand for the kind of economy, social responsibility, and chic that motor scooters now represent. Models with paired front and rear wheels for stability, permanent canopies for weather protection, and battery electric power for economy have become commonplace and manufacturers from China, India and Korea now vie for shares of the lucrative American market. Vespa has even returned to the United States, remaining strong despite the flood of cheaper, look-alike retro models.

California remains one of the top scooter markets in the United States and a large number of brands eagerly battle for market share in the Southland despite rigorous statewide emissions standards that have driven up the cost of manufacturing. Scooters have become a realistic alternative to automobiles for many motorists who have grown weary of traffic snarls, high gas prices, and difficult parking. Riding a scooter can also be a source of fun and is entertaining in ways that even the most expensive cars cannot be. Like the Autopeds of almost a century ago, modern motor scooters offer a sense of freedom and independence and buzzing around on one tends to confer on the rider a kind of youthful sophistication not associated with any other type of two wheel vehicle. Scooters seem to have become the mechanical equivalent of the bow tie; they are not right for everybody, but those who dare to embrace them will earn a measure of respect, distinction, and personal satisfaction known to few others.

Control and dynamic analysis of two-wheeled road vehicles

Postby Lock » Mon Jan 09, 2012 8:55 am

Imperial College London is a science-based institution with a reputation for excellence in teaching and research. Founded 1907.


Their Control and Power Research Group has put together a page of PDFs here:

"Control and dynamic analysis of two-wheeled road vehicles - papers of historical interest"
Image
W J M Rankine (On the Dynamical Principles of the Motion of Velocipedes)
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149701.PDF
This paper from 1869 is of historical interest only; it is presented in four parts, together with a short supplement. It sets out to analyse “balancing”, “steering” and “propulsion”. The analysis given is elementary, without differential equations, and in our view is of little lasting technical value. Its main claim to fame stems from the fact that it was one of the first papers ever written on (steady-state) bicycle dynamics.

F J W Whipple (The Stability of the Motion of a Bicycle)
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149699.PDF
The first formal analysis of the self-stability of a bicycle was presented in Whipple’s famous paper in 1899. On page 326, Whipple presented the linearized equations of a straight running bicycle in matrix form. As Hand pointed out in his 1988 MSc thesis, there are two typographical errors in the linearized equations presented by Whipple. Once these errors are corrected, Whipple’s linearized equations correspond exactly to the now accepted benchmark equations by Meijaard et al. (2007).

F. J. W. Whipple memorabilia
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149698.PDF
A small collection of F. J. W. Whipple memorabilia courtesy of the Wren Library, Trinity College Cambridge. This file contains three obituaries which were published in Nature, Engineering and Who Was Who, all appearing in 1943 following his death on 17th March of that year. The Cambridge University Reporter of June 13 1899 announces the Smith Prize: Whipple received an honourable mention for his Essay “On the stability of the motion of a bicycle.” An extract from the University of Cambridge Historical Register shows Whipple’ part I and part II Mathematical Tripos results. These where not “politically correct” times with the female students listed separately!

G G R Routh (On the Motion of a Bicycle)
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149700.PDF
This paper by G.R.R. Routh (1899), son of the famous E.J. Routh, focuses on the small perturbation behaviour of the Whipple-like bicycle. Four problems are considered: (I) The behaviour of the machine with its steering locked; (II) the machine’s oscillatory behaviour around steady-state straight running, (III) Steady-state cornering, and (IV) small oscillations around a steady-state cornering condition. An interesting analysis shows the conditions under which a bicycle under steady cornering behaves like a simple inverted pendulum.

Timoshenko-Young
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149696.PDF
The Timoshenko-Young bicycle model is a very simple mathematical description of a bicycle’s roll dynamics. Recently, this model has found favour with the control systems community. Timoshenko and Young derive the model using a conservation of angular momentum argument. The wheels are represented with pure rolling non-holonomic constraints, the steering assembly is not raked, and the bicycle is represented by a single point mass. Despite the extreme simplicity of the model, the equations of motion are surprisingly complex.

D E H Jones (The Stability of the Bicycle)
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149702.PDF
Jone’s Physics Today article from 1970 (re-printed in 2006) is widely known for the simple “unridable bicycle” experiments that illustrated some of the dynamical features of bicycle steering mechanisms. Contrary to popular belief, the front wheel gyroscopic moment play very little part in a bicycle’s “ridability” at normal and low speeds. His experiments highlighted the critical role played by the trail and the front steering geometry. Jones did not do any dynamical modelling; his experiments mainly focused on gyroscopic effects, the effects of trail on machine stability and on the steering torques that resulted from roll.

R S Sharp (The Stability and Control of Motorcycles)

This 1971 paper represents an advance in the analysis of the straight-running motorcycle. Unlike the Whipple model, the tyres are modelled as “force and moment producers” rather than as rolling constraints. These forces and moments are linear (and time varying) functions of the tyre’s side-slip and camber angles; relaxation effects are included. Aerodynamic effects were not explicitly included. This paper shows that the tyres are responsible for a steering shimmy oscillation called “wobble”. The “wobble” and “weave” modes are analysed in detail. The stabilizing effect of a steering damper on the wobble mode, and its destabilizing effect on the weave mode are demonstrated.

Tuesday 18 August 1998: “The art of the motorcycle”, an exhibition held at the Guggenheim museum between June 26 and September 20 1998. Perhaps more than any other single object of industrial design, the motorcycle can be considered a metaphor for the 20th and 21st centuries. Predating the automobile by 25 years and the airplane by 36, the motorcycle was the first form of personal mechanized transport to emerge from the industrial age. The motorcycle represents technology, engineering, innovation, design, mobility, speed, rebellion, desire, freedom, love, sex and death.

An interesting account of the historical development of the motorcycle can be found at the Guggenheim museum site: http://www.guggenheim.org/exhibitions/p ... cycle.html

R S Sharp (Stability, Control and Steering Responses of Motorcycles)
http://www3.imperial.ac.uk/pls/portallive/docs/1/42149704.PDF
This paper (2001) follows on from the author's prior reviews of the stability and control of motorcycles in 1978 and 1985. The paper treats the earlier material in tutorial fashion and then adds some more recent research. Small perturbations from straight running and from cornering equilibrium states are analysed. Steering control by handlebar torque and by rider upper body lean torque are compared. Theoretical analysis, experimental measurements and general experience are linked where possible. By 2000, there was a strong movement towards the use of stiff frames for large high-powered machines, as well as the widespread use of multibody dynamics software for automated analysis. The paper has a good mix of nonlinear and linear analysis, which emphasises such things as sensitivity analysis and mode shapes.

Colibri 1915
Factory owner Emil Jern in Gävle Sweden designed a auxiliary engine for bicycles. It was first called Furir and mounted on the front wheel of a common bicycle. Whole unit with its patent was sold to 2 Gävle inhabitants who started the Engine Factory Furir. Earlier their main product was pumps and 1919 the company was reconstructed and named Colibri. This became the first support engine for bicycles in Sweden and was sold in large series.

Colibri
Colibri was also available as a frame mounted engine 1919. It had several similarities with FN from this time. 1921 a twin was manufactured. This was mounted across in the frame. The company went out of money 1923 and the remaining spare parts were sold and advertised as long as to 1928.

Not coffin up

Last Updated: 9:12PM BST 13 Sep 2003

The motorcycle hearse mentioned by Christopher Booker (Notebook, September 7) may be the only operational vehicle of its kind in Britain, but an excellent example can be seen in the Norfolk Rural Life Museum at Gressenhall.

The hearse is drawn by a Norton motorcycle, and consists of a sidecar chassis with wooden platform on which the coffin is laid. It was the brainchild of a local worthy to provide a speedy and cheap method of transporting the bodies of departed inmates for interment to the parishes of their origin.

It seems that this was too much even for the guardians of the day, and the vehicle was never used for the purpose for which it was intended. The same cannot be said, however, for the coffin, which was of the re-usable variety with a hinged side from which the pauper's body could be slid into its final resting place.

The Steam Car Club of Great Britain

Postby Lock » Mon Jan 09, 2012 2:05 pm

The Steam Car Club
The Club was formed in recognition of the ever increasing interest in steam cars and the need for a standalone club dedicated to that need. It has since grown into the largest and most respected Club in Europe and possibly the World, it has produced for many years the best known magazine in the World THE STEAM CAR which is now in full colour!

The membership spans many countries including Australia, New Zealand, America and Europe. Membership is open to all. You don't need to own a steam car, and whether you have an old or modern car or a steam bike; it's your interest and knowledge that is valuable.

The club through its web page, forum and links page (with hits of over 30 million to date) has developed a method to help all Steam Car users, covering maintenance, restoration and the general running and advice including encouraging the regular examination of the boiler pressure system. Advice and support for anyone interested is always available. JOINING The Steam Club of Great Britain is the best route for enthusiasts specifically showing an interest in steam cars. Another important activity of the club was the building of its ever increasing historic archive, and pattern register thus aiding people with technical support for all cars in preservation. The archive has been built up over many years with the help of the Science Museum and Stanley Museum as well as Auburn Heights in America and many other organisations and people to which we are grateful. Preserving our heritage with steam on the road is essential.

MOTOR BICYCLE.

Many cyclists are awaiting 1902 in the hope of a reliable motor bicycle being placed on the market at a cheap figure. A well-known English cycling writer says that "the price of motor bicycles for next season will remain about the same as that obtaining this year." It is well to realize this, in view of the airy statements made in some quarters that we may expect to see huge reductions before very long. These announcements are often given on mere hearsay, and when repeated go a good way towards repeating the £5 bicycle fallacy so persistently pushed forward a little while ago. The statement, in fact, is calculated to do considerable harm both to the trade and to the public. While heartily desiring that the price of motor bicycles be as low as possible, we do not want to see the shoddy article, dangerous to life and limb, placed on the market. At present the first cost of motor and fittings, with the special frame and motor tyres, is too high to allow the £25 motor bicycle to be thought of.

A Motor Bicycle Wrecked.

On Saturday afternoon a motor car that was said to be travelling on the wrong side of a street in Rockingham ran down a motor bicycle on which H.W.Bean and his brother Stan were riding. The latter was thrown clear, but the former was thrown under the car, the wheels going over his legs, which were badly bruised and lacerated. Stan Bean was also bruised and lacerated. The driver of the car did not stop. The motor bicycle was wrecked.

`Couple of news bits...

M.DELAURIER has devised a new compound liquid for exciting electric piles. It consists of 20 parts of proto-sulphate of iron in 36 parts of water, 7 parts of sulphuric, and one part of nitric acid. This he declares to be the most powerful and economical exciting liquid, attacking iron, zinc, and other metals, without any evolution of hydrogen or bi-oxide of nitrogen.


The velocipede mania is spreading. It must have its run like any other fever. It may become chronic, though some wise heads are predicting a speedy crisis and collapse; or perhaps the collapse is to come before the crisis, or they may be simultaneous! Just at present, however, the inventive genius of many countries seems to be concentrated upon the construction of velocipedes of every novel style. If announcements may be credited, there is - or is going to be, which amounts to the same thing in this fast age - a monocycle, which can be driven sixty miles an hour; a bicycle warranted to run a hundred miles an hour on a single rail of a railroad track; and probably tricycles and quartercycles of indefinite speed. The machines are gradually being furnished with all conveniences, even to lanterns and lunch-boxes! Nobody feels terrified, even when such accidents occur as did recently in Cincinnati; when a young man taking a velocipede lesson in the fourth story of a building, lost the control of his machine, and was precipitated through a guarded hatchway to the cellar beneath. Such an occurence only incites story-makers to circulate reports that in certain cities the velocipedes are driven so fast that every collision results in the total disappearance of both rider and machine! No fragments are ever found!

The centenary of the birth of George Stephenson was celebrated with great display at Newcastle-on-Tyne, and on a lessor scale in Chesterfield, London, Berlin, Vienna, and Rome. It is singular that at this moment the eyes of the world should be turned on electricity as the new motive power. An electrical tramway is now running in Berlin, and electric bicycles at Paris, while some surprising experiments have been made with the storage of electricity.


`Guess the Europeans were so excited about Stephenson as it was the railways that had "taken off" as motorized transport since George had designed his first steam railway locomotive in 1814:

Credit for the first road-going locomotive usually goes to Richard Trevithick. From Wikipedia:
The Puffing Devil
Trevithick built a full-size steam road locomotive in 1801 on a site near the present day Fore Street at Camborne. He named the carriage 'Puffing Devil' and on Christmas Eve that year, he demonstrated it by successfully carrying several men up Fore Street and then continuing on up Camborne Hill, from Camborne Cross, to the nearby village of Beacon. His cousin and associate, Andrew Vivian, steered the machine. This is widely recognised as the first demonstration of transportation powered by steam. It inspired the popular Cornish folk song "Camborne Hill".


Nice pic of Trevithicks' Puffing Devil, with a row of other late 20th-century puffing devil designs in the background:

The Leisure Hour, 1896

Postby Lock » Tue Jan 17, 2012 3:36 pm

http://www.victorianlondon.org/transport/horseless.htm
THE HORSELESS CARRIAGE.

BY A PASSENGER.


YES. There can be no doubt of it. Everyone has read and heard about "automotors" by this time, or seen pictures of them in the illustrated magazines, but somehow these have got mixed up with engravings of submarine boats or flying machines, and all have stood still. One has looked like any vehicle in Long Acre, and the other suggested a new patent reaping-machine. It is not till you have sat on the box of a phaeton and been for a spin along a dusty road at the rate of some ten miles an hour without whip, reins, or anything to drive in front of you, that you can realise, however faintly, the future of a "horseless carriage." I have just returned from a short excursion in one of them, but the length of the trip has nothing to do with its effect upon the passenger sitting on the box with no animal trotting before him below the splashboard. "It takes two gallons for eighty miles," remarked the coachman by my side, as he whisked round one of the corners of the road. He spoke of them as if they were a seasoned "pair," safe to do so long a day's work, but they were harnessed somewhere "inside," in the rumble, and they certainly made themselves felt there to some extent, especially when we stopped for a moment to pick up a man at the roadside. Then they gave the vehicle a pulsation not unlike that communicated to a gig by a blown horse when pulled up after a sharp trot. But our motive power came from senseless petroleum instead of sinews, and a "relay" was ready in a can, rather than a wayside stable, and was fed with fire, not oats.

The impression, however, produced by the "drive" is not measured by the perceptible throbbing of the hidden engine (that, indeed, suggests a panting horse), but by the revelation of a new method of wheel progress which promises to revolutionise the whole world of man's movement upon the face of the earth, let alone the trade of all carriage builders, harness makers, and stable keepers. When men began to travel by "rail" they certainly had a new sensation, but there was the old one of having something in front "pulling" you. The name of "horse" remained, only it was called an iron one. And then a special road had to be made for it and for that which it drew. Without this it could not start nor work, and often it took years of toil before the road could be ready. When made, moreover, it would not be diverged from for a moment without danger; but your swift "horseless carriage" is not "drawn" at all, and needs no track to be provided for it. Given the carriage, the roads of the country are at its command. The bicycle, too, though it has appeared in swarms, is really no new thing, but a butterfly - which has broken the husk of the old go-cart. Its motive power is the same, being only a fresh application of the rider's legs. Of course we all know that the horseless carriage is, in fact, no recently modern invention (indeed, the wisdom of our ancestors is committed to the truth of the saying that there is nothing new under the sun), for it has been running in France for the last two or three years, and even some half-century ago efforts were made to bring it into use in Scotland but it is virtually a revelation to the British public which has slowly taken it in, and is beginning to realise the revolution in road traffic which it heads.

Who can conjecture the changes likely to follow in its train? At present, so to speak, only a little puff of smoke or steam is left behind it, to disappear in a minute, but before long a manifold material procession is bound to come after the first English automotor. And this prodigious development will be the result of one of the shortest Acts of Parliament the Legislature has ever passed in these realms. The ponderous traction engine which we have all seen grinding along the country road, when touched with the magic wand of law can be potentially transformed into a multitude of vehicles, spinning or steadily advancing along the countless tracks which cover the land. What will be the good of laying down sleepers for "light railways" by the side of the turnpike or the lane when a short automotor train threads them, picking up the farmer's produce here and there on its way to the nearest station? Perhaps we shall even see a roomy horseless truck among the implements of some farmyards, ready to carry his sacks far more quickly than a crawling team. But it is in the passenger traffic of the country and the town that we may expect to see the greatest locomotive change in store for those who go about on wheels. Railways will take their place among the old-fashioned methods of procedure, and perhaps our grandchildren will smile to think of stage coaches having been ever talked of as prehistoric, since they may possibly be seen running again . . . horseless. Then, may be, too, the deserted wayside inns on the old main roads will have a new lease of life, and the horn (steam this time) be heard heralding the approach of the "Highflyer" and the " Rapid."

But city streets, they say, will be most notably invaded. When I reached the London terminus, after my trip with the two gallons of petroleum, and saw the crowd of omnibuses and cabs waiting harnessed for their fares, and presently heard the tramp of countless hoofs as we drove home, I wondered what the thoughts of all those horses would be if they knew those which were then filling my mind. Some say that one great drawback to automotors will be the alarm caused in the minds of these patient toiling creatures, but possibly they will take an unexpected cheerful view of a revolution which sets them free from bit, blinker, and whip. And they might well chuckle to think of the little appreciated help they give in the guidance of a loaded omnibus through crowded streets. As it is, the best driver owes more than he might admit to the intelligence of his horses. They see where to go, and what to avoid, as well as he. But an automotor has no eyes, and it will need the creation and training of a new set of coachmen to steer down Bond Street or Cheapside when one is full of carriages stopping suddenly to deposit shopping ladies, and the other is choked with crowds hurrying to and from the city. We hear much now of "street accidents," but what may they become should London be invaded by the "horse-less carriage"? And then think how it would be if one of them were to bolt. We read of active policemen catching the reins of a runaway, and saving the lives of those sitting helplessly behind it, but who would snatch at the nose of an iron cab over which its driver has lost control? There are "cons" as well as "pros" in the outlook of a street invasion by blind unfeeling motors It is in the use, however, of private ones on country roads that many contemplate their adoption with safe promised enjoyment. A "Tour on Wheels " will bring a decidedly new sensation: no anxiety about uncertain stabling, or sudden lameness no tiresome carriage of hay or oats; no breaking of harness in out-of-the-way places. Of course there is the chance of an inside pipe going wrong, or a cog coming off, and then - where are you. far from an intelligent artificer to repair the damage, or manufactory where you can buy what you want?

Again, there is no "loving" of a reservoir; you must feed it, indeed, but it does not care to be patted. You can't give it a carrot or lump of sugar before you start. Perhaps some ingenious inventor will enable a motor to neigh instead of "toot," but it can never become an affectionate companion who knows your voice and likes to be stroked. There is bloodless satisfaction in steering the best horseless carriage, however swiftly and safely it may carry you where you would go.

Perhaps it is in the application of the new motive power to bicycles that we shall see it most enjoyably appreciated, for no living love has yet been felt for the "bike." I suppose the rider will be enabled occasionally to use his pedals for a change, instead of the quart of oil beneath his saddle. This being so, a field of fresh career is open to the wheelsman, without the vexation of delay by reason of accident to his boiler or oil tank, for he would only have to fall back on the power of his legs, and, barring extra weight to be carried, be not much worse off than he was before.

I have said nothing about the present stage of manufacture reached in the making of "motors," for, of course, they are yet in their infancy, and we may well expect as much improvement to be made in them as in any new mechanical discovery. Those in experimental use now will, if widely employed, come to be looked on with the same curiosity as is aroused by an inspection of the first steam engine that was made a hundred years ago.


...amusing today to read motorcyclists neighing about how with electric bikes they would miss the noise and stink of gas power...

Hansoms and growlers together,
Fares don't care for your love or your war!
In this coming November
Just please to remember
You've a rival - the new motor car!

Punch [on a cab driver's strike] 1896


Murdock's pupil, Richard Trevithick, also invented a horseless carriage; he took out a patent for it in 1802, and drove the first he made full size through the streets of Camborne, and with Vivian drove it under steam from Camborne to Plymouth, whence it was shipped to London, and exhibited where Euston Station now stands. On the City Road, too, ran Hancock s steam coach. In fact, with "Steam on Common Roads" before them, engineers must smile at the present enthusiasm. With our greatly improved roads and proper care on the part of those in charge, there is no reason at all why such carriages should not work successfully, if the Acts of Parliament passed in the interest of the horse-owners were repealed. Our legislators have never favoured horseless traffic - witness the way in which they have treated steam-rollers and traction-engines; though it must not be overlooked that badly built houses may be dangerously shaken by heavily moving machinery. Steam, however, is not so likely to furnish the motive power as oil or electricity. One of the most entertaining features of this revived interest in what it is the fashion to call automobility, is the series of laments as to the supersession of the horse expressed in almost exactly the same terms as in Trevithick's day. The railways also were to have wiped out the horses, but have they? There are more horses now than there ever were.

article in The Leisure Hour, 1896


Hehe... "...if the Acts of Parliament passed in the interest of the horse-owners were repealed."... and now we need to get all these laws in favour of the horse-less carriage repealed.

Anthony and Frederick Reckenzaum

Postby Lock » Tue Jan 17, 2012 5:40 pm

Austrian brothers Anthony and Frederick Reckenzaum built the first electric boat in England, in 1882:
Reckenzaun_1882.jpg


Their electric boat "Volta" crossed the Channel and back on 13 September 1886....

...and from The Electrician, July 6, 1888
AMERICAN NOTES.
(FROM OUR OWN CORRESPONDENT.)

New York, June 23rd, 1888.

A great deal of public attention has been directed during the last week to the performance of the electric launch "Magnet," the first boat of its kind, I believe, to make its debut in New York waters. This boat was built early this year on the designs of Messrs. Anthony and Frederick Reckenzaum. She is 28ft. long, 6ft. beam, 3 ft. deep amidships, and draws 2 1/2ft. of water by the stern. She is equipped with a Reckenzaum motor, weighing 4201b., driving a two-bladed screw 18in. in diameter. She carries 56 cells of the battery made by the Electrical Accumulator Company, weighing about 2,4001b. All told, the machinery weighs about 3,0001b. A speed of 12 miles an hour can be attained, but it is at the expense of the total mileage. The accumulators are arranged along the bottom of the boat, snugly under cover. Above them runs a bench nearly the whole length of the boat, giving seating accommodation for nearly 20 passengers back to back. The accumulators are arranged to work in a straight series of 56, or in two parallel groups of 28 cells each. They are capped at the top with rubber to prevent slopping in a rough sea, and stand in a bed of sawdust. For some time past this boat has been in use as a pleasure craft on the Passaic River, getting its charge at the Electrical Accumulator Factory on the river bank, at Newark. At the present time another launch, much larger, is being built at one of the yards up the Hudson River, also to be run by storage, the Electrical Accumulator Company supplying the batteries. I hear that the peculiarity of this boat will be the disposition of the batteries, which are to line the sides of the ship, leaving room in the middle for a cosy cabin. This boat is said to be nearly ready, so that before long New Yorkers will become familiar with the spectacle of boats driven by their own ballast.

French Electric Tandem around 1900, ridden by Dacier & Jalabert

This tandem électrique was an invention of the Frenchmen de Clerc et Pingault. On Mai 22 1897 this tandem rode 1 km in 57 4/5 seconds.
The tandem will not have been lightweighted. What would have weighed those four batteries? A weight that the frame should also bear in addition to the two cyclists. Also I see nothing that looks like a brake.

De Clerc & Pingault will soon develop and produce other vehicles.

e-Bicycles in The Netherland
One source suggests that Gazelle in The Netherlands in 1915 has designed an electric tandem too, with an 8- and 9-volt battery.

But only between 1935 and 1937 the first Dutch electric bicycle (no tandem) will be sold. It is an electric bike with 12-volt battery, developed by Philips and built by five Dutch bicycle manufacturers including Gazelle. In total 117 were built.
So no smashing success.

Today, this is quite different in the Netherlands. Even many of my peers have an electric bike. I don't. For now I think that such an e-bicycle is too decadent. But I admit: they are increasingly common.

José Meiffret 1962

Postby Lock » Fri Jan 20, 2012 6:23 am

Different kind of power-assist, seen here:
http://cycling.ahands.org/bicycling/datewithdeath.html
Date with Death
by Clifford L. Graves, M.D.
September 1965
A tense group of people was gathered on the freeway near the German town of Friedburg on July 19, 1962.

Herr Heinemann had painstakingly measured off the official kilometer. Half a dozen timekeepers of the International Timing Association were fiddling with their electrical equipment. Captain Dalicampt of the French occupation forces deployed his men at strategic points along the cleared Autobahn. Chief Schefold of the federal highway department dispatched a sweeper crew. Adolf Zimber lovingly wiped a bit of invisible dirt off the windshield of his massive Mercedes. Reporters were asking questions, scribbling notes. A photographer was angling for a shot. José Meiffret was about to start his Date with Death.

Of all the tense people, Meiffret was the least so. A diminutive Frenchman with wistful eyes and a troubled expression, he was resting beside a strange-looking bicycle. A monstrous chain wheel with 130 teeth connected with a sprocket with 15. The rake on the fork was reversed. Rims were of wood to prevent overheating. The gooseneck was supported with a flying buttress. The well-worn tires were tubulars. The frame was reinforced at all the critical points. Weighting forty-five pounds, this machine was obviously constructed to withstand incredible punishment.

On this day, at this place, on this bicycle, José Meiffret was aiming to reach the fantastic speed of 124 miles an hour. Everything was now in readiness. Meiffret adjusted his helmet, mounted the bike, and tighten the toe straps. Getting under way with a gear of 225 inches was something else again. A motorcycle came alongside and started pushing him. At 20 miles an hour, Meiffret was struggling to gain control. His legs were barely moving. At 40 miles, he was beginning to hit his stride. At 50 miles, the Mercedes with its curious rear end was just behind. With a wave of his hand, Meiffret dismissed his motorcycle and connected neatly with the windscreen of the Mercedes. His timing was perfect. He had overcome his first great hazard.

Swiftly, the bizarre combination of man and machine gathered speed. Meiffret's job on penalty of death was to stay glued to his windscreen. The screen had a roller, but if he should touch it at 100 miles an hour, he would be clipped. On the other hand, if he should fall behind as little as 18 inches, the turbulence would make mincemeat of him. If the car should jerk or lurch or hit a bump, he would be in immediate mortal danger. An engineer had warned him that at these speeds, the centrifugal force might cause his flimsy wheels to collapse. Undismayed b the prospect, Meiffret bent down to his task.

He was now moving at 80 miles. News of the heroic attempt had spread, and the road ahead was lined with spectators. Everybody was expecting something dreadful to happen. Herr Thiergarten in the car showed Meiffret how fast he was going by prearranged signals. Meiffret in turn could speak to the driver through a microphone. "Allez, allez," he shouted, knowing that he had only nine miles to accelerate and decelerate. The speedometer showed 90. What if he should hit a pebble, an oil slick, a gust of wind? Ahead was bridge and clump of woods. Crosscurrents were inevitable.

In his pocket, Meiffret carried a note:
"In case of fatal accident, I beg of the spectators not to feel sorry for me. I am a poor man, an orphan since the age of eleven, and I have suffered much. Death holds no terror for me. This record attempt is my way of expressing myself. If the doctors can do no more for me, please bury me by the side of the road where I have fallen."
Who was this man Meiffret who could ride a bicycle at such passionate speeds and still look at himself dispassionately?

He was born in 1913 in the village of Boulouris o the French Riviera. Orphaned at an early age, he had to got work to support himself and an aging grandmother. One day, as he was hurrying home from work on his ancient bicycle, he was run down by a motorist. José was badly shaken, and his bicycle was ground to bits. Distraught, the motorist offered to buy José a new bicycle. It was a beauty. Before long, his bike was his life. When he wasn't riding, he was reading. Under the skinny frame and deep-set eyes burned a fierce ambition. Someday he was going to beat the world.

His first race was a fiasco. Totally unprepared, he entered a 120-miler through the mountains and was promptly dropped. His competitors made fun of him, and a doctor told him that he had a weak heart and should never race. That night José cried himself to sleep.

The man who changed José's career was Henry Desgrange, the founder of the Tour de France. Desgrange had a villa on the Riviera, and José wrangled an introduction. Desgrange sensed the compelling drive in the delicate body, and he made an accurate assessment,
"Try motor-paced racing, my boy. You might surprise yourself."

José did just that. With fear and trepidation he entered a motor-paced race between Nice and Cannes. Without any indoctrination whatever he was immediately at home. Riding smoothly and elegantly, in perfect unison with his pacer and in complete control of himself, he was out front all the way and finished a full seven minutes ahead. The people went wild.

Encouraged by this success, he arranged to go over the same course behind a more powerful motor. This ride was an epic. Intoxicated by his speed, he barely missed a car in Nice, grazed a dog in Cannes, scraped a sidewalk in Antibes, had a flat five miles front the finish, and yet hung up a new record of 1.02 for the 40 miles. He had found his destiny.

How could a rider like José make a splash before he had caused a ripple? Racing behind motorist is quite different from racing in a group. Behind motors, the speed is higher, the pedaling faster, the concentration greater. It is like a continuous sprint. A motor-paced rider must have suppleness rather than strength. And he must have flair.

But a motor-paced rider is not made overnight. Just as José was beginning to hit his stride, the war broke out. When he returned to Paris after five dreary years of captivity, he was as far from his goal as ever. Motor-paced racing has a long and honorable history, but only a few men have ever excelled in it. In America, the sport died after "Mile-a-Minute" Murphy did his amazing ride behind a Long Island Railroad train in 1899. In Europe, the sport survived. On the road, the hour record was set in the thirties by the Frenchman Paillard with 49.362 miles. Meiffret raised this in 1949 to 54.618. Paillard immediately raised this figure to 59.954 but he almost got killed in the attempt. To beat Paillard, Meiffret selected a special circuit in Germany, the Grenzlandring. Cheered by thousands, he covered 65.115 miles in an hour and could have done more if his motor had been running right. All this required incessant training and complete concentration. Meiffret's philosophy was "to become what you are."

Although his exploit at Grenzlandring brought him great acclaim, it did not bring him any money. In fact, none of Meiffret's rides brought him any money. All his life, he had to fight poverty. He supported himself with odd jobs and with occasional writing. His latest book Mes rendezvous avec la mort, earned him the 1965 Grand Prize for Sports Writing and the Prix Sobrier-Arould of the prestigious Académie Française.

In an effort to improve his position in 1951, he decided to race behind cars instead of motorcycles. Cars are bigger and faster. Here, the man to beat was Alfred Letourneur, an expatriate Frenchman who had covered a measured mile behind a car on the Las Angeles freeway at 108.923 in 1941.

Meiffret's first attempt was behind a Talbot. To his consternation, he could not get past 70 miles an hour. Aerodynamic engineers told him to modify his windscreen. After months of toil and heartbreak he tried again. A 20-mile stretch of road south of Toulouse was especially cleared (even the President of the French Republic was detoured on that day). On his first run, the Talbot faltered. On his second run, he lost contact and was almost flattened by the wind. On his third run, he hit a bump and was in free flight for 50 feet, but he held on and finished the kilometer at 109.100 miles per hour. Letourneur had been beaten, but not by much.

Undisputed record man of the hour and of the kilometer on the road, Meiffret next turned to the track at Montlhery. Here, the Belgian Vanderstuyft had ridden 78.159 an hour behind a motorcycle in 1928. But Montlhery in 1928 was new. In 1952 it was old. The pavement was starting to crack, and the turns were atrocious. The track superintendent shook his head. He had seen many try. But Meiffret was determined. On the appointed day, he rode his first lap at 80 miles per hour. Suddenly, coming out of the turn on the seventh lap, his bicycle started bucking. Nobody knew what actually happened. Perhaps the pedals, which had less than an inch of clearance, scraped. At any rate, Meiffret flew through the air, hit the ground, tumbled three hundred feet, slid another twenty, and came to a rest, a quivering mass of flesh. Horrified attendants carried him to an ambulance, and newspapers announced his imminent death. That night surgeons found five separate skull fractures. Unbelievably, Meiffret lived through this ordeal.

Then followed a long period of recuperation during which he fought as much for his mental sanity as for his physical health. In search of peace, he joined the Trappists at Sept-Fons and led the life of a monk. During this time he made continuous improvements on his bicycle, wrote his first book (Breviary of a Cyclist), and corresponded with hundreds of people. Thus he learned of a new freeway at Lahr in Germany where he might gain permission for another attempt on the flying kilometer. In the fall of 1961, when he was already forty-eight, he reached 115.934 miles per hour. This ride convinced him that he could reach 200 kilometers (124 miles) an hour. Thus we find Meiffret in the summer of 1962 on the freeway at Freiburg, riding like a man possessed.

The Mercedes performed flawlessly. People could not believe their eyes. What they saw was the car in full flight with and arched figure immediately behind, legs whirling, jersey fluttering, wheels quivering. "Allez, allez," gasped Meiffret into the mike. In the car, the speedometer crept past 100 mph, then 110 and 120. Anguished, Zimber looked into his rear-view mirror. How could Meiffret keep himself positioned? It was fantastic.

At the flat, the speed had increased to 127. Faster than an express train, faster than a plummeting skier, faster than a free fall in space. Meiffret's legs were spinning at 3.1 revolutions per second, and each second carried him 190 feet! He was no longer a man on a bike. He was the flying Frenchman, the superman of the bicycle, the magician of the pedals, the eagle of the road, the poet of motion. He knew that he must live in the rarefied atmosphere for eighteen seconds. When he passed the second flag, the chronometers registered 17.580 seconds, equivalent to 127.342 miles an hour.

Meiffret had survived his date with death.
