1. Instead of using gasoline or diesel fuel like motorized vehicles, bicycles turn our energy, created by our bodies, into kinetic energy. A bicycle can convert up to 90% of a person's energy and movement into kinetic energy, making it the most efficient transportation mode to date.
2. Energy transformation
4. While riding a bicycle, the muscular energy of the rider gets transferred into the heat energy and kinetic energy of the bicycle. Heat energy heats the rider's body.
