Dynamo powered lights have been around almost as long as the bicycle has had gears. One problem? Most if not all of them had to make physical contact with a spinning wheel to be powered, that is until now. Enter the Magtenlight. It uses the same dynamo tech, but instead of a physical spinning apparatus it uses 28 magnets attached to the bike’s spokes. As they pass by the dynamo, power is generated and the included lights are lit. No physical contact, no friction, no slow down.
Two lights are included and rated at 15 lux a piece, that is assuming you’re traveling at about 9mph. A small on board capacitor or battery stores additional juice for up to 4 minutes when you pause or brake at stop lights and stop signs.
