Battery-free bicycle lights
You will never run out of power with Reelight magnet-powered bicycle lights. The bicycle lights generate their own power so you never have to worry about flat batteries that need to be changed.
This is how the bicycle lights work
The lights are based on the electrodynamic induction principle, and work by screwing two magnets onto the spokes and mounting the light onto the wheel axle. The light contains a copper wire coil and current is generated when the magnet passes the light. As the wheel rotates, the light will flash accordingly.
Reelight bicycle lights mean less batteries in the environment
Batteries are very bad for the environment and contain substances like cadmium, mercury and lead, all of which can seep into ground water and cause damage. Reelight bicycle lights do not use batteries so your bike ride is good for your health and environmentally-friendly.
