Do You Want a Wheel?

In an age of scarcity, the bicycle remains one of the most energy-efficient modes of transportation available. Did you know?

  • The Bicycle is the most efficient vehicle ever devised; a human on a bicycle is more efficient (in calories expended per pound and per mile) than a train, truck, airplane, boat, car, motorcycle or jet pack.
  • If Americans replaced just one in five of their average length car trips by bicycling, each driver would spare the atmosphere more than one ton of carbon dioxide emissions. Collectively, the effect would be comparable to taking 48 million vehicles off the road.
  • Nearly half of all trips in the U.S. are three miles or less; more than a quarter are less than a mile, distances easily covered by bike while saving you money and getting you fit.
