Bicycle

A bicycle, or bike, is a pedal-driven land vehicle with two wheels attached to a frame, one behind the other. First introduced in 19th-century Europe, it evolved quickly into the familiar current design. With over one billion in the world today, bicycles provide the principal means of transportation in many regions and a popular form of recreation and transport in others.

The bicycle has affected history considerably in both the cultural and industrial realms. In its early years, bicycle construction drew on pre-existing technologies, while more recently bicycle technology has contributed in turn to other, newer areas. Beyond recreation and transportation, bicycles have been adapted for use in many occupations, in the military, local policing, and in sports as well. A recurring theme in bicycling has been the tension between bicyclists and drivers of motor vehicles, each of whom argue for their fair share of the world's roadways.
