I want to do some experimenting with an electric bike/motorcycle but spent all of my project money during a recent hurricane, in part on a Honda 2200 generator. So I got an idea to possibly take a small motorcycle (or even a mini bike) with a busted engine and take the engine out and replace it with a mount for the generator and one for a treadmill motor (I have an old treadmill). I believe that the treadmill motor is a 130VDC motor and is already wired to a PWM controller. Maybe a mini-bike would be more doable to start with. I don't expect the motor to last forever or that I'm going to ride this thing to work but it would be fun to try out. Does this sound doable? Any recommendations? After I save up a bit more, I'd like to invest in some batteries and a hub motor.
