Starting after July 4, the Newton and Tremont Street sides of the South End Library will have a bike-sharing docking station as part of the city of Boston's Bikeshare program. The library's location is clearly seen as a community hub/stop for the South End. The Boston system is called Hubway Bikeshare. It will start sometime in July with 600 bikes. Cambridge and Somerville are likely to start similar programs. Read more about it at Boston Biker and Mass Bike.
