The Reelight SL250 bicycle light works with a convenient magnet that can be screwed onto the spoke. When the wheel turns, the magnet passes the bike light which has a coil of copper wire. And then the light comes on. Simple, effective and unique.
Reelight is a Danish manufacturer of bicycle lights. The patented battery-free bicycle lights generate their own eco-friendly lighting through magnets in the spokes and a small generator integrated into the lights. Mounting Reelights is very easy and once mounted you have nothing to worry about. Summer or winter, day or night, Reelights are always on as soon as you start cycling: that is the power of Reelight.
Reelight products are available at Juncker Bike Parts.
