oldpecan: a wheelchair motor would be a good choice since it's probably 24v, which means you won't need crazy RPM to get 12v out of it.

A slick would definitely make it easier. The tire-side-contact of the generator hub is far from ideal. But the goal was to make do with stuff I already have, or could easily scrounge, and also to retain the bike's usability - pluck it off the stand and ride it up slippery, snowy hills if desired.

I mounted the motor/generator and did a test pedal tonight ... and blew out a 6v light bulb. Whoopsies.

Also posted details on how I made the stand: Building a pedal power bicycle generator, ghetto style - EcoRenovator

Goal for this weekend is to recharge my camera batteries... WITH! MY! LEGS! Woo.
