Got version two done. Now I will make a new tranny to double the geardown, and then I will double my voltage on the motor. This should keep wheelspeed the same while halving amp draw assuming I don't goose the throttle more on startup.

I may change the gearbox to include a clutch so that the motor can start up with no load. This will keep me from having to push off on start. So far, I have logged about 20 miles on the new frame. A 6 mile trip costs me a whopping $0.0138 in electricity assuming 10% charger inefficiency. Version three is in the works, I am converting my santa cruz bullet to a pedal/electric motorcycle. Version four is also in the works with a very high power system. Most likely a 90v 200a ESC and matching motor.

This thing is so much fun, I can't believe it took me so long to get it done. I will be selling gearboxes in the future most likely.
