Stokemonkey
While it might sound like it has to do with adolescent-onset blindness, Stokemonkey is an electric bike conversion for a Xtracycle. Backing up a bit, an Xtracycle is a bike extension designed for hauling cargo. It’ll give you 30 miles per hour on level ground, and about 20 uphill. While the range can vary significantly, normal use provides about 50 miles between charges.
Extra kudos to the site for providing neat wattage information. For instance: a normal biker going 14 miles per hour uses about 100 watts of power. (That suggests the bike generator people are really sweatin’ it to get 200 watts.) Meanwhile, Lance Armstrong can provide about 500 watts for a burst of 20 minutes.
