The Copenhagen Wheel transforms the bike you already own, quickly and easily into an electric bike with regeneration and real-time environmental sensing capabilities. The wheel captures all the energy you create while braking and cycling and stores it for when you need an extra push. At the same time, sensors in the wheel are collecting information about air and noise pollution, congestion and road conditions.

According to Ritt Bjerregaard, Lord Mayor of Copenhagen, "Our city's ambition is that 50% of the citizens will take their bike to work or school every day. So for us, this project is part of the answer to how can we make using a bike even more attractive."

Watch Copenhagen’s Lord Mayor in action, together with Toronto Lord Mayor David Miller, experiencing the Copenhagen Wheel, live from the Danish capital.

The wheel is connected to the rider’s iPhone (that can be easily attached to the bike’s handlebars) and with its sensors it can monitor speed, direction and distance traveled and even the proximity of other rider’s friends.

The Copenhagen Wheel was unveiled on December 15 at the COP15 United Nations Climate Conference. The project was conceived and developed by the SENSEable City Lab for the Kobenhavns Kommune. The prototype bikes were realized with the help of our technical partner Ducati Energia and funding from the Ministry for the Environment. Progical Solutions LLC provided technical support for the iPhone control of the bikes.
