I am restoring a 1940's columbia cruizer. Today I got an idea. How possible would it be to mount a motor on it? I don't mean the kind of thing where you have to pedal it up to speed, but more of a minibike setup. I don't know very much about motors, but I am quite handy with tools. I don't want to have to do major welding. I suppose what I am really wondering is, are there any kits available for this sort of thing?
