Video Pick: Flywheel Bicycle

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.
