It’s a modern day message in a bottle. A social experiment by marketing agency Razorfish, the #UseMeLeaveMe bikes are equipped with the technology that will constantly locate the bikes by GPS and tweet their locations so followers can find free bikes closest to their location. Each of the 20 bikes have their own name, personality, and will recognize when they are immobile so they can tweet the location for users to come and hop on. Will the bikes end up in Alaska? Will I end up riding one of these back to New York? It’s all totally possible – and we’ve got the story right here.
