Bicycles are human-powered or motor-powered vehicles with two wheels attached to a frame in a line. They were introduced in the 19th century in Europe and over 1 billion were in existence by the early 21st century. Bicycles are used for transportation, recreation, exercise, sports, and have had a large effect on culture and industry. The basic design of modern bicycles has changed little since 1885 but materials and manufacturing have improved.
