How about editing your post so that it makes sense?

the real question (and i'm being serious here) is why are E bikes SO HORRENDOUSLY UGLY?

example of a nice clean lines, beautiful bike:



VERSUS the trainwreck grotesque godawful ugly E Bike:

A nice clean ebike. Battery pack with carry handle means easy charging at work/school/wherever.

There are plenty of ugly pedal only bikes, as well as ugly ebikes.

I don't know, put an XtraCycle on that bottom one and you might just have something.

Kick ass homebuilt. No extra chains, sprockets or motors hanging off. Total weight of 54.6lbs, and the BMC geared hub motor will climb any slope you'd want to ride on.

Will travel faster and far further than any hubmotor powered ebike with the same Wh capacity onboard. (sorry Lowell, but it's simply true)

Utter garbage. Send it to me & I'll dispose of it properly for you, I'll even pay shipping.


Replace the front brake with something like a small geard hubmotor w/no freewheel and regen braking, slap some lithium in a backpack, perhaps even route the cables through theframe and you end up with something pretty similar but with a boost to it.

Maybe something like this: https://www.users.bigpond.com/solarbbq/P2-B.htm

I agree except that with my previous bb drive because I could keep adding boost at any speed so I continued to do so, 250 watt motor only but speed when a combination of your self and a low powered assist is fun.
A hub motor (low powered) will only assist to a certain point after that you are on your own, so assuming a passably fit cyclist the hub may only run 50% of the time if that, but with the bb or mid drive you can achieve usefull boost all the time and if you can't resist that boost you use more power but go faster so you may actually use more power.
Now stick a bb 0r mid drive in the trike in my avatar and you will be talking a great jump in effiency due to reduced drag. and you won't see the motor or batteries either.

What we need is cheap safe lithium or firefly batteries now, weight/range is the true sticking point on ebikes I feel, and that weight reduction range increase needs to occur without affecting current price point of an ebike greatly.IMO

No argument there. My bike with fairing installed is pretty close to a bent, but a bent w/ fairing is pretty slippery. I've taken the fairing off my bike, and am concentrating on 0-40mph instead. The goal is to be under 6 seconds to 40mph, and 3.5 seconds 0-100ft.

Lose to what? 0-40mph in 7 seconds is not bad for NiMH power. What's your 0-40mph time again?https://video.google.ca/videoplay?doc...08324&hl=en-CA

Take it to the drag strip, for a good laugh.It's not hard to go fast.
Try some distance without pedaling on your heavy ebike.

I wouldn't want to bet on Currie to be the leader out front in the
ebike world, look at the crappy 250 watt brushed cheapo motors they advertised as 450 watts, and used them on the Mongoose line
of e bikes, the motors are worth about $35 wholesale. If they do use a geared hub it will probably be some Chinese ripoff that lasts about a week.

heh i must have one of the good ones. my geared currie motor has been working for months at 49 volts
no problems.

i just added extra batterys to my friends izip and it works great to. these cheap motors got kick

just repack the gearbox with good bearing grease and its good to go.

I might be willing to take you up on the offer. You might be faster and you might go further but once your batteries go flat you'd be history I need to re-gear the velomobile because on the flats my cadence is 110 and I'm only doing 27mph. I can't spin any faster. When I re-gear I hope to drop my maximum cadence to 98-100 and bring the speed to over 30mph. BTW I'm street legal here in Oregon, no motor assist beyond 20mph



Seriously now. I would have preferred a motor inline and through the gears rather than a hubmotor. I think it is more efficient and far lighter. However what was more important to me was stealth. You don't see or hear my hubmotor. The motor controller is way up front in the dark of the nose. All wires are out of immediate sight. One would have to look hard to tell that it was power assisted. Usually the people can't see the power assist for the velomobile.

I'm running a NuVinci hub on my Giant. It's been a damn nice hub, and has had no problems with the excess weight I make that thing haul. The only other hub I've ridden that compares to it in feel and ruggedness is my Rohloff. When I build myself up another e-bike I'll be using another NuNinci.
