Scientists unveil 'bicycle innovation' in Copenhagen


A team of scientists from an American university say they have reinvented the bicycle wheel.

The Copenhagen Wheel is a hub containing motor and batteries which can be fitted to the rear wheel of almost any bike, providing a boost to the cyclist whenever needed, say developers.

It has been unveiled at the UN Climate Summit by the team from the Massachusetts Institute of Technology.
