Soylent green car generator exercycle!! Need I say more? I was thinking of a front wheel mount or rear and hooking up a generator/alternator to the bike while riding. I would never run something like that inside and would have a belt run bench system in the garage for home use.. Perhaps one from a geo or other small car would fit on the mounting rack of a friction drive.. This is not for a stationary but to perhaps charge an electric hub or battery or for power stereo system. Whatever.. I just thought I should throw this out there for someone to pick at.
