Lightbulb Too cool! DIY bicycle with mechanical (flywheel) regenerative braking, assist (video)

I haven't even finished watching the 3 minute video and am posting it for its sheer awesomeness:

Quote:
Maxwell von Stein, a 22-year-old graduate of The Cooper Union, built bicycle that uses a flywheel to store energy. Instead of braking, Max can transfer energy from the wheel to the flywheel, which spins between the crossbars. 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.
