Several companies also operate dockless bicycle sharing systems in the Bay Area such as Jump Bikes, Lime, and Spin. These dockless systems differ from the Ford GoBike system in that bicycles can be parked freely on the street (or at a bicycle rack in the case of Jump) and do not need to be docked at a designation station. Currently, Jump is the only dockless bicycle sharing company that operates in San Francisco while other competing companies operate dockless systems in other Bay Area cities such as South San Francisco, Oakland, and San Jose.
