Bicycle
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A bicycle, or bike, is a small land vehicle with two wheels, pedals, and a metal chain connected to cogs on the pedals and rear wheel. The name comes from these two wheels - the prefix "bi-" meaning two, and the suffix "-cycle" meaning wheel. It is powered by a person riding on top, who pushes the pedals around with his or her feet.
Cycling or riding bicycles is an important way to travel in several parts of the world. It is also a common recreation, a good form of low-impact exercise, and a popular sport. It is also the second most popular spectator sport in the world. Bicycling uses less energy per mile than any other human transport.[1]
