A DIY E-bike Conversion on the Cheap

Cars That Think

I'd read about such friction-drive arrangements and had followed the work of a cyclist in Australia known as Kepler who had devised a clever articulated mount that allows the motor to retract from the wheel when not applying power. I next needed to decide on an electronic speed controller (ESC) to power the motor. James Provost.

DIY Electric Car

I have never run out of juice. I have grown to prefer the feel of it over a power rack, and my wife seems to like it too.
