Bicycles

One of the great inventions of the world. As John Ryan’s book Seven Wonders: Everyday Things for a Healthier Planet says:
The Bicycle: The most energy efficient form of travel ever invented and the world’s most popular transport vehicle. Pound for pound, a person on a bicycle expends less energy than any creature or machine covering the same distance. Handy for the one out of four car trips in the United States that are less than a mile.
