Leave it to the Japanese to come up with a pedal-powered roller coaster. The Skycycle at Washuzan Highland Park in Okayama has side-by-side tandem pedal-powered carts with seat belts, which sounds pretty scary considering the course. If you got on that thing with Lance Armstrong you'd be peeing your pants all over the place. Sort of like how I'm doing now. Walking to the bathroom is for suckers.

More pictures after the jump.
