Neat.
The Copenhagen Wheel turns the bike you already own, quickly and easily into
an electric bike with regeneration and real-time environmental sensing capabilities.
The wheel harvests the energy you input while braking and cycling and stores it for
when you need a bit of a boost. At the same time, sensors in the wheel are collecting
information about air and noise pollution, congestion and road conditions.
The Copenhagen Wheel differs from other electric bikes in that all components are
elegantly packaged into one hub. There is no external wiring or bulky battery packs,
making it retrofittable into any bike. Inside the hub, we have arranged a motor,
3-speed internal hub gear, batteries, a torque sensor, GPRS and a sensor kit that
monitors CO, NOx, noise (db), relative humidity and temperature. In the future,
you will be able to spec out your wheel according to your riding habits and needs.
