Flywheel Bicycle Powered By Kinetic Energy

Maxwell von Stein, a 22 year-old Cooper Union graduate, built a bicycle that uses a flywheel to store energy. Instead of braking, he can slow the bicycle by transferring the kinetic energy from back wheel into the flywheel—which spins between the bars of the frame. Then Max can send the flywheel energy back to the wheel when he wants a boost. [Source]
