If the walking bike wasn’t your speed, check out the Jump Bike a custom job that’s a different kind of hybrid bicycle. Instead of pedals, you power the bike by saddling up and walking (or running) along with it. When the desired speed is reached, the feet come up and you let ‘er roll.
Looks effective, but sure is weird (and we just couldn’t resist). Hit the jump for another pic and video of the bike in the action. ::Jump Bike via ::designboom
