Get a hub motor

[Drunkskunk]

The Stokemonkey setup allows the motor to go through the gears on the bike. You can gear down on hills, which should (????)more than make up for the efficiency lost in the extra chain, unless you live in Kansas.

If you look at the Puma hub motor, it's really no different than Randy's setup other than the motor is in a hub. It still has gear reduction between the motor and wheel and it has a very efficient brushless motor.

Please give the Puma motor specs and my motor specs to compare since you offer your expert opinion. If looks are what you go by then by all means get the prettiest motor you can find. The girls will love it!

I'm still waiting to see the specs on this Volcano god motor of yours.

I finally hit 50mph up a 4.25% grade today. 80.4km/h actually, but close enough. This is still with fenders, lights, backpack containing rain gear, plus my 'tank bag' with chargers and cords. 100% commuting trim.

Almost 2500km on the X503 hub.

Lowell's claim is proof enough for me.

FWIW, people can seamlessly corner-pin video of Drainbrain screen on a freespinning bike to the video of a bike on the road... so, even video can be counterfeit. 8)

If anyone would like to dispute Lowell's claim, feel free to show the logical basis.

I suspect both Lowell and Randy of using small gas engines in addition to electricity. Prove otherwise!

You're trolling again, Randy. You're so deluded that anytime people say things that don't support your views, you assume they must be lying? To what gain? Lowell can't possibly "prove" his results; no one can simply by speaking. The only way to "prove" anything like this is to have the results duplicated independently. And while nobody else is using Lowell's exact setup, others have run hub motors at higher voltages and gotten equally predictable results.

Hi

I don't doubt lowells claim 1 bit? he is using a very powerful motor there with a modified controller and high capacity cells, if the conditions allow there is no reason why he shouldn't be able to go that fast?

I can do 43mph on the Puma at 72V, I personally don't think e-bikes should be going so fast and 50mph for me is way too fast, but that's just me! I don't think you really need to go much over 30mph

Lowells bike is to all intense and purposes a light electric motorbike and not an assist machine as such, it couldn't even really be considered as a moped as most mopeds cant reach 50mph, using the X5 you can make a very powerful machine if you have the batteries and controller to suit.

I am amazed that the police officer sent his friend on his way, If a policeman clocked me at 50mph it would be curtains for sure, even if you were peddling, I think I couldn't really argue too much if I got stopped at that speed, I am pretty sure I would be up in court or receive a hefty fine of some sort as it would be pretty obvious I was riding an uninsured un registered un taxed motor vehicle, once you jump over the legal limit it becomes a motor vehicle here in the UK.

I have a throttle limiter so I can stay within the legal limit and my bike is geared so I can keep up by peddling over 30mph, it would be tough to prove in court that it was not the motor but myself alone moving the bike, the UK law has some grey areas which could be easy to exploit however 50mph on the flat I doubt Lance could peddle a 70lb mountain bike to 50mph on the flat :lol: mind you he might be able to those Lycra dudes have ways of upping the power don't they! ha ha

Hi all
knoxie is right the law in the UK is an ass it states max speed for a Ecycle propelled by its motor alone is 15mph, propelled by the rider pedeling and the motor going 15mph, peddle power only as fast as you like up to the stated road limit.This makes me and a lot of UK ebikers mad and car drivers as well. I have set a more sensible speed restrictions on myself after rideing through town a lot a speed of 25 mph with both pedel and motor, thats only 5mph slower than the 30 mph town speed limit,the cars get less annoyed and it would incourage more people to change to ebikes as a town commuter.

Hi Lowell
wll done, too fast for me maybe you should reclasify your beast as a Emotorbike.
As for randy trying to get randy to behave himself is like beating your head against a brick wall, you get hurt and the wall has some more blood on it to prove it has hurt somone else.
The only thing we can do is to ignore him, if we rise to the bait he keeps taunting us with it just builds up his ego.

 

[Lowell]

While my bike may be fast, there are HPVs out there that are faster, so it's not just speed that defines an Ebike vs. Emotorcycle. Sam Whittingham http://en.wikipedia.org/wiki/Sam_Whittingham is only a few hours from here, and his bike could break speed limits anywhere, just on human power.

http://www.wisil.recumbents.com/wisil/records/fastest_ever.htm

So for my experience here has been that if it has pedals and doesn't make noise, it's A-OK. I've gotten nothing but postive comments from everyone I've met, including cyclists. Except for one jerk at a bike shop who told me flat out that he could out drag me on his pedal bike :lol:

As for Randy (or anyone else) trying to cause trouble, that will simply not be happening here.

You want to delete a post from the guy who started the thead, he's already edited or deleted most of his comments from this thread anyway, geezus get a life already.

First of all, I don't have any problem with people that don't agree with me. If everyone agreed, there would be no worthwhile discussion going on. Randy's one line comment is simply a troll. Had he worded something like:

"I don't believe your 100lb ebike can go 50mph up a hill, show us proof"

I would simply direct him to my video of climbing the same hill at 75km/h from a standing start. Then I would point out that my relatively aerodynamic bike requires much less watts at speed than unfaired bikes. And lastly, the bicycle speed and power calculator shows that the power level required for 50mph on a 4.25% grade with a 100lb bike falls well within the power capability of an X5 hub motor.

And I would also like to mention that I'm still accountable to Fechter and KnightMB, as well as open to members comments and criticism. Obviously we can't please everyone, but we do our best to keep things running smoothly.

Unedited Videos give a great way of comparing. In this fourm where members are untrusting of anything new other than hub motors I will believe a video 99% over the facts from a hub motor owner here when it concerns efficiency and speed or hills that they have there facts based on.
Just start a Unedited Video section on here. Having the trip route map and elevations is easy. Round trips make real avrages and only +750 unlimited NO pedaling bike figures to 100 lb max may be a good limit for a ebike.. ? Complete trip videos DO TELL 99% of of what you may need to know. Leave the sound on. Drag bikes and 25 mile plus commuting ebikes need to be seperated.

 

[Lowell]

No need for another video section.

Much like dynos, anyone can make a display read optimistic by lowering the shunt resistance and/or calibrating to a different wheel circumference. There are enough knowledgeable people here that I think any false performance claims can easily be spotted. For example if someone said their 1600W unfaired mountain bike was doing 50mph on the flats, I'd call BS.

Heres is 3 miles in 4 minutes on a full suspension MTB with a 20 amp limit at 72 volts = 1440 watts MAX. battery power out.Sitting up right as well.Going any faster on a bicycle is senseless.

45mph with 1440W input? It appears the aerodynamics of your bike fall somewhere between a triathlon bike and superman position.

You're happy at 45mph and that's great for you, no need to hate on faster bikes.

No need to hate efficient motors. Lets see some torque at 12 mph :lol:
