Up with Pedal Power! Pedal power reaches new heights in Japan with their roller coaster, the Skycycle at Washuzan Highland Park in Okayama. Powered by people pedaling the bikes on a track, this roller coaster creates a real pedal power high! What happens when the guy in front of you slows down? What if your legs get tired? Looks pretty safe with the little pink baskets in front of each cart. Check it out here. If you speak Japanese, great, but words are not necessary.
