Copenhagen Wheel

The Copenhagen Wheel is a bicycle wheel that stores and delivers electric energy to power a bicycle. Energy comes from an external battery charger, and from regenerative braking when the rider back-pedals as in a coaster brake. It is a Pedelec and includes a built-in electric motor and a 48-volt lithium ion battery and is controlled by a smartphone app. The motor analyses the topography and pedaling activity to decide whether to deliver power. Range is approximately 30 miles.[1]

The wheel is made by Superpedestrian, based on technology from MIT.[1] The invention got a free advertising boost when it was featured in Showtime's seventh season of Weeds.[2]
