revolights. join the revolution.

What are Revolights? Revolights consist of 2 thin profile LED rings (white in front, red in back) that mount directly to each wheel rim (just below the brake calipers) using a series of rim specific clips. Power is supplied via a thin wire to the hub where a lightweight and slim, USB rechargable polymer lithium-ion battery is held in a special bracket. A small magnet is secured to the fork to provide speed and orientation information to the rings.
