Similar to the way electric cars have regenerative breaking, the very attractive Maxwell von Stein, 22, a graduate of The Cooper Union, invented a bike that harnesses your pedaling power. His beta bicycle uses a flywheel (pulled from an old Porsche) spinning between the crossbars to create energy. According to NPR's Science Friday, "The flywheel stores the kinetic energy until Max wants a boost, then he can transfer the energy back to the wheel using a shifter on the handlebars."

This would do wonders while riding on the hilly streets of San Francisco, yes? It's a good way to get a kick in your bike sans the use of gasoline.

"I'm not trying to reinvent the bicycle. It's a platform to learn more about his new hybrid," he explains. Von Stein's goal is to a) get a job and b) put his flywheels on all cars. He stands an excellent chance of doing both. But don't take our word for it. Watch Max demonstrate his wonderful doohickey in the following video:
