While rival General Motors focuses on car sharing, Ford is going for two wheels instead of four. The Blue Oval is teaming with bike-sharing specialist Motivate to launch a bike-share service in the San Francisco Bay Area. Called GoBike, the Ford service will have 3,500 bicycles available in San Francisco, East Bay, and San Jose by the end of this summer. By the end of next year, Ford expects to have 546 GoBike stations and 7,000 bikes in operation. The automaker claims that will make GoBike the nation’s second-largest bike-share program. So it looks like GoBike will be more than a publicity stunt or pilot program.
