The Sky Cycle is a human pedal-powered roller coaster at an amusement park in Japan. Rather than simply closing your eyes and screaming for the duration of the ride, the only way off, is to pedal you way to the finish!
Implications - When it comes to interactive rides, the Skycycle takes the cake. If you wanted to hop on this particular ride, you would first need to make your way over to Okayama, Japan and find the Washuzan Highland Park. Not only do you get an invigorating thrill being high above the treetops, but you can also get a pretty good workout having to pedal your way to it on the tracks.
