Smart, responsive and elegant, the Copenhagen Wheel is a new emblem for urban mobility. It transforms ordinary bicycles quickly into hybrid e-bikes that also function as mobile sensing units. The Copenhagen Wheel allows you to capture the energy dissipated while cycling and braking and save it for when you need a bit of a boost. It also maps pollution levels, traffic congestion, and road conditions in real-time. 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.
