Capital Bikeshare is a joint bikesharing program in Arlington, Alexandria and the District of Columbia. The program has more than 1,800 bikes available at over 200 stations throughout the area. Specially-built bikes are kept in a network of docking stations. Members use an electronic key to check out a bike, ride to a destination served by the network, and return the bike to another docking station near their destination. You can join Capital Bikeshare for a day, 3 days, a month or a year. The system is designed to be used for transportation; to go from point A to point B within the network and dock the bike, making it available to other members. Trips up to 30 minutes long are free, with fees starting to accrue after 30 minutes.
