Unveiled at the COP15 United Nations Climate Conference, The Copenhagen Wheel transforms ordinary bicycles 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. Controlled through your smartphone, it also maps pollution levels, traffic congestion, and road conditions in real-time. The Copenhagen Wheel project demonstrates that small intelligent implementations can lead to major changes." Check out the video for a full demonstration.
