Bicycle gears Pinion P1.18, Nuvinci, Rohloff.

Pinion

This is a very interesting approach, linear gears at the centre of effort of the pedalling motion (and near the ideal centre of gravity). very wide range of gear ratio and the use of a belt drive train. Seems like the ideal system. The only negatives might be the unproven reliability, the high price and the non standard frame.
