APS - Adaptive Pedaling System.m2v

The drive system on a normal bike is already extremely efficient. Where a bike is inefficient is areodynamic drag.

Sorry to say but gears have nothing to do with this pedaling system.

It's goal is to allow pedaling standing up without the waste of energy of the traditional crankset.

you could of just changed gears instead of doing something as complex as that
