The time change isn't here quite yet, which means many of us are still riding our bikes home in the dark after work.

Inhabitat writes that the system uses 28 magnets attached to the bike's spokes. As they pass by the Magtenlight in the center, power is generated. The lights are all lit in a way similar to a dynamo system, but without any physical contact or friction, so no wear and tear on the device, and no resistance to slow you down as you ride.
