Magnic Light Dynamo-powered Bike Light System
"Magnic Light is the first contactless dynamo-powered bike light system with no additional components in the wheels. Energy is drawn from the rotating bicycle wheels without any physical contacts, and thus without friction. Electricity is generated in the lights by making use of eddy currents created by strong magnets (International Patent Pending PCT/EP/2012/001431).
With this new technique lights can be completely encapsulated with no batteries and no external cables but with enormous efficiency. In 2013 Magnic Light was awarded with the ISPO Brandnew Award of ISPO Munich as winner of the category bike parts. For a short first impression, watch the Magnic Light video."
