I have managed to save about $800 to build a motorized bicycle. I have also thought about buying one of the complete bike/motor kits. I'm pretty mechanically inclined, can weld, and fabricate if needed but would prefer not to spend lots of time building or fixing an old frame. I've looked at the Felt bikes and I really like them but are there any others I should be considering? Is there a good, reliable source for the motor kits? Oh, and I will be sticking with a 50cc or smaller motor because my wife doesn't have a motorcycle license and she's said she would like to ride it too. If it were your money, what would you get and why?
