No, thats not a Simon. Social Bicycles, or SoBi, have created "a GPS-enabled device that affixes to the rear wheel of a bike set to be offered up to others. Those others can call up a mobile app to locate available rides and retrieve the password necessary to unlock them. Once done pedaling they can just lock the thing up again and it's immediately added to the queue of available human-powered chariots."
Real dope concept. I wonder how it'll work in major cities. Especially in car-centric metro areas. I can see it being viable in New York but not so much in Los Angeles.
