Multiple gears on the crankset only to make a 3 speed bike. Possible? How? Answered
I have a bike with an electric motor on the back wheel.
My bike is fixed gear, so it's hard for me to help the motor when pedaling at medium speeds (>20km/h). On the other hand, once I'm out of batteries and I have a hard time going uphill.
I would like make my bike a 3 speed bike without messing with the back wheel.
Is it possible to have 1 gear at the back and 3 gears at the crankset to make my bike a 3 speed?
My idea would be something like a hub gear, but that stays on the crankset instead of the back wheel.
