@stopglobalswarming I pedal to get rolling from a dead stop, then it's throttle only as the gearing i'm using would force me to spin at a rediculous rpm, the chainring is freewheeling IPS tandem cranks.
Just came upon this video and i'm sure you've improved the bike since but for those that do not know the NuVinci hub, I think you would improve your joy of it by short shifting in very small gradual steps. If you momentarily shut the power off a bit, you can use two fingers to slide the transmission up a notch, hit the power curve of the motor and improve the momentum. It's a delicate balance because the gears are not fixed but the tendency is to overdo it at first. Have fun!
The 20" wheel, originally i wanted to mount the motor infront of the fire in the space provided by a smaller wheel, problem is that chainline was impossible. 2nd is that a smaller bike is easier to fit inside elevators etc as i take this bike to work and various other places, personal preference as well i like the lower to the ground feel.
budget, ouf, rough guess is well over 2500$ so far, not including battery/charger/bms, + 1000$
The video above is on 10ah Lifepo4, switching to Lipo .
I'm curious about why you used a 20" wheel for this bike-- a bike with a gear reduction that would allow you to use whatever size wheel you want.
It seems to me that you could have better ride quality and traction, lower rolling resistance, and better bottom bracket height if you used a larger wheel.
In other regards, the bike seems better than a usual moped, even before taking into account any legal advantages of e-bikes. Can you give us a general idea how much you spent on this bike?
Impressive range and speed,if you had a aero body it would really increase the speed and range,bikes have a lot of drag.

Clean build, looks fast. Do you have to pedal much with it?

you idiot, you're riding in the gutter!
altogether impressive, especially if that run is a single charge.

@petedude2lu3 Your depth perception is malfunctioning. He is not in the gutter.

i love it.
i got a Canadian Tire Schwinn AL1020 with a brushless 180 w hub in 16" wheels in 2006 and rode it 12 months a year.
I just finished installing a 250w 36 volts controller and an brushless hub 18" wheel from a scooter into the Schwinn.
I had to cut the frame to install the wheel.
Can't wait for tomorrow to take it for a spin.
I love your video man!!!
E-bike is the way to go!!!

what are the speeds ?
jmygann 2 years ago
On level ground lowest gear ratio 40 km/h
Max speed so far on GPS 60 km/h and i'm not pushing it to the limit yet. ( brand new build, above is ride no. 3 !)
