A human and a bicycle are the perfect synthesis of body and machine.

Just as the ideal of classic Greek culture was the most perfect harmony of mind and body, so a human and a bicycle are the perfect synthesis of body and machine.

Possibly the tragedy of the bicycle is that it was invented too close in time to the car. In the historical scheme, pedal power hardly got under way before the combustion engine appeared and, not only took over the roads, but changed our view of machines. We've forgotten that pedal power is a potent form of energy.
