New York City will see the introduction of a new bike sharing system this fall that uses an iPhone app to help users location a bike.  Social Bicycles will provide bikes equipped with GPS devices locked to one of the wheels.  Members of the Social Bicycles network can borrow a bike, ride it to their location, then drop it off.  When a bike is not in use, it can be located via the GPS and iPhone app. 

The best part of this new bike sharing system is that bikes can be parked and locked just about anywhere, eliminating the need for special docking stations.  Read more about the Social Bicycles program on CrunchGear.
