Bicycle is a vehicle with two wheels set one behind the other on a frame. A rider powers a bicycle by pushing two pedals around in a circle. People all over the world use bicycles for transportation, recreation, and exercise. Several of the world's countries produce millions of bicycles per year.
In some nonindustrial countries, the bicycle is a more important means of transportation than the automobile because it costs far less. Some people use the bicycle to make a living. In many Asian countries, for example, pedicabs provide public transportation. These vehicles consist of a bicycle with an attached cart that can carry two passengers. Bicycles also are used to deliver small packages and mail.
