You really can't fault MIT's branding strategy here. Debuting at the biggest climate change conference since Kyoto, its Copenhagen Wheel is a mixture of established technologies with the ambition to make us all a little bit greener and a little bit more smartphone-dependent. On the one hand, it turns your bike into a hybrid -- with energy being collected from regenerative braking and distributed when you need a boost -- but on the other, it also allows you to track usage data with your iPhone, turning the trusty old bike into a nagging personal trainer. The Bluetooth connection can also be used for conveying real time traffic and air quality information, if you care about such things, and Copenhagen's mayor has expressed her interest in promoting these as an alternative commuting method. Production is set to begin next year, but all that gear won't come cheap, as prices for the single wheel are expected to match those of full-sized electric bikes. Video after the break.
