On my $40 craigslist bike hubmotor kit, the controller rated at 24 volts actually accepts 36 nominal, and the hardware is actually good to 60 if I wanted to do a boot swap on the control parameter. ( based on the power chips painted id numbers) New unlimited 80 volt controllers are a buck fifty, but decent battery cells are expensive or really big & heavy. The 80 volt one I found also doesn't need hall sensors in the motor so it only can sense output frequency for speed. Buy a 20" hub and lace to a 28 wheel and use pedal crank sensor only.

Sadly, doing all this means I need a trailer, because my bike is full suspension. Nowhere on the frame to hang more than 36v 10ah lipo.
