A bicycle sharing system or bikeshare is a service in which bicycles are made available for shared use to individuals who do not own them.

  • For users, bikeshares remove some of the primary disadvantages to owning a bike, including theft, lack of parking or storage, and maintenance.
  • Usually implemented by governments to reduce traffic congestion, air and sound pollution, and revitalize public spaces, bikeshares have also been cited as a way to connect users to public transit networks.
  • There were an estimated 200 bikeshares worldwide in 2010—see the Bikesharing Map.
