This pedal powered roller coaster, in Okayama, Japan, is high above the ground and has amazing views. I guess the lawyers in Japan aren’t as out of control as ours here in the US. There are no guard rails on either side and the riders are only held in by a simple seat belt.
Energy for the SkyCycle pedal powered roller coaster is powered by humans who pedal all the way around. Two riders fit per cart and sit/pedal in a tandem style. The ‘bikes’ also have baskets in the front for storing riders belongings and standard bicycle brakes. More pictures and video of the SkyCycle after the break.
