Battery-free Bike Lights

06 September 2017

Reelight, a Danish manufacturer, has designed bicycle lights that activate as soon as the rider begins to pedal.

Powered by coin-sized magnets, the lights are attached to the bike’s spokes. Additionally, the lights are waterproof, switchless and easy to install.

To see the lights in action, view the accompanying video.
