That's an 'inertia' motor. You pedal like crazy, it rotates, and stores energy, so when you want to pass someone at the end of a race, you have 'boost' of power when it's engaged.

Maybe I'm missing something, but that doesn't make any sense to me. Wouldn't you be wasting energy (speed) by trying to store it, rather than just peddling faster to move faster?
