THIS BIKE BUILD HAS BEEN SCRAPPED BECAUSE IT HAS NO BRAKES. :lol:
Hello strangers. This is a comprehensive introduction/Q&A session on the subject that brings us all here, ebikes.
In the summer of 2010 I deiced I wanted to buy a motorcycle. After a lot of research I set my heart on 250cc bikes or less, like Ninja's and Eliminators. The price , maintenance, and portability of these machines along with several life changes have changed my mind. I do not have a garage. One never came up in my price range close enough to get me to pull the trigger.
Also, the danger of the speed. I know several people that have died in accidents, and the first body in a casket I ever saw was because of a motorcycle crash. I looked into that box at a pile of dead human biology for a long time and saw my reflection. That, and I'm a rambling mess of bad luck with too many stuntman tendencies.
So I stepped down to mopeds/scooters. I've crashed several things at 30mph, bikes, sleds, skis, wagons, myself at the rate of gravity, so these seemed more reasonable. For the past 2 years I've been pining over scooters, once again, not buying because of price/maintenance/portability/service support/life changes. I had my heart set on something like a madass125 or a people150. But they aren't exactly abundant. So I started looking into Ruckus, Zumas, and Elites, but the level of excitement wasn't there for me. 3 years later and I still have a 2 wheel lust in my heart, and no where to go with it. I'm am not very impulsive it seems.
Inspiration strikes at an estate sale 3 weeks ago. In the dark bowels of a former existence, were two bikes, a 1950's Radio Flyer, and a 1965 Schwinn Typhoon 2 speed automatic.
http://a2.ec-images.myspacecdn.com/images02/30/385633c1e59040d49cfcbb018795cf45/l.jpg (this isn't mine) Mine needs some rust removal and paint along with a bucket of WD-40 to remove the painful seat and a new front wheel.
It rides true and is solid steel. I walked it home 2 miles in the blistering cold and snow as my girlfriend drove by in her climate controlled cage, laughing mercilessness out of the steaming window
The woman running the estate sale asked if I was going to turn it into a motorcycle. I was puzzled by the idea of this, is that even possible I wondered? It is, and was. Conversion kits are cheap, excitement returned! I'll slap a 4 cycle engine on this baby, looks like a gas take will fit right into the top of the frame, disk brakes, lights, mirrors, waaaahoooo! I'm no mechanic, but none of this appeared to be beyond my ability.
Then "the man" put a hole in my heart, can't title these things in my state, can't get a licence without a title, and can't get insurance which means I can't ride anything I build on a public road. Devastation. I could create such a beautiful machine, a symbiotic partner for my 2 wheel adventures.
I sulked for days. As I was walking down an aisle at lowes(they pay me to do such things), I found myself gazing at the gas powered trimmers. Then the electric powered trimmers.
Hmmmmm, aaaaa, wait, yeah! Neuron fireworks so powerful they sent shivers down my spine.
Battery tech has taken off in the past decade, the phone in my pocket is basically a laptop, these trimmers are going toe to toe with similar gas trimmers. The same power that can move these out door machines is the same power that could move me on a bicycle. ELECTRICITY!!!!!!!
To the internet I scurried, delicious morsels of information awaited. Street Legal, enough
Mad science has begun! Scattered scraps of paper with formulas and notes. Showers neglected, relationships on hold, work even more agonizing.
60 of the past 72 units of time mentally devoted to design and specification. Osmotic transfer during sleep cycles.
It can be done, expensively but within my budget for a scooter.
So here I am. This site has been a useful resource. 3 days ago I didn't know the difference between a watt and amp. Now I am soaring on enough hubris to pick parts for a bike I intend to ride.
I do have some questions. Well, firstly, given the frame choice, any design input you may suggest would be really appreciated. I am not sure if a mid hanging bag will be optimal in that frame (26 inch wheels btw) or if i should put a rack on the back. I do not know a lot about bikes. I can change a tire and (sort of) tune gears, work with brakes, but my knowledge is basic.
The starting point was the motor, a 9C 2806.
From there is still cloudy. Battery I want to go with LiMn or A123. Ping LifePo4 maybe.
My concerns with each of these is C rate, I have read that Pings have very low C, and give the amount of stress I could put on the motor with higher C
I would be more comfortable with 3-4 C battery types, so I can run 2 C with a little wiggle room. I've also read I would want to keep my power draw under 25 amps to prevent melting Hall Wires. So I don't intend to go too crazy. 48v-25ah appears to be the upper bound(given the motor), and 48-15 the lower. 3-5 years of this battery is still 5-10 times less expensive than gas, so I can justify the price.
I gather I should pair this with a controller that can run 25. If I go ping, is it possible to alter the settings to 10-15 amps to remain at the 1-1.5 C ? Infineon is the most likely choice. Or is that even necessary.
I have more questions, but I have to serve my terms at wage prison. Different Bat Time, Same Bat Channel.
