I have an old EV Global ebike that I use for parts. I am thinking of building a bike with another frame and parts from this bike. I think a Heinzman 36 volt motor will fit in this 24 volt hub. Anyone know? Is the gearing the same? Finally is there somewhere I can get new or used Heinzmann parts in the US? I'm thinking I can save a little just getting the motor, not the whole hubmotor assembly. I'm also interested in other parts like gears (especially the nylon gear) and screws.
