MIT students have developed the “Copenhagen Wheel”, a device intended to be attached to any standard bicycle to turn it into an electric. The Wheel contains a motor, batteries, and gear system all inside a single hub, and is intended to help cyclists with hilly terrain and over long distances. Interestingly, there are also sensors that will link with cycling-related mobile apps. Of course, the hub isn’t available for purchase at this time – but it did just win the James Dyson Award, so odds are that the Copenhagen Wheel might just end up being available at retail in the near future.
