The bike, created by German designers Tom Hambrock and Juri Spetter, is fixed to the rider with a belt system suspended from the machine's frame under which the rider is fixed into pace. The bike is an entry into the annual James Dyson Award for technology , innovation and design open to international students and founded by the Dyson vacuum cleaner inventor.Called the Fliz, it needs the user to build up speed by running and then lifting their legs to settle on foot rests at the hub of the rear wheel.Momentum then sends the rider and bike on their way, a little like cartoon stone age man Fred Flintstone's car.
