David has it right (http://www.los-gatos.ca.us/davidbu/pedgen.html http://www.los-gatos.ca.us/davidbu/pedgen.html). You just can't generate that much power--his burst output is about enough to run a desktop computer. I researched this a while back because of an ingenious idea to decouple power and pedalling speed by putting a pedalled generator, a supercap, and an electric motor on a bicycle frame. Sadly, it would've been about 2x as heavy as a normal electric bicycle, and 60% as efficient.
