The Knog Cobber Lil Rear Light offers great visibility due to its large lumen output and sophisticated beam angle of 330 degrees. Even traffic in side streets can see the light! Thanks to the removable hook-and-loop fastener supplied, the cobber can be mounted on most seatposts and head tube profiles and is then easy to attach and detach using the magnetic holder. Charging is quick and easy via the USB power supply.
