The makers of the Copenhagen Wheel from M.I.T.'s SENSEable City Laboratory claim that the new features mark the advent of "Biking 2.0," a new era based on smarter bikes and easier rides. The wheel is certainly a step in that direction; it includes sensors for detecting distance, speed, direction, all of which are beamed via Bluetooth to the rider's iPhone. The wheel also includes a built-in lock that sends the rider a text if tampered with.
