Knog came out with the Cobber to allow a 330 degree of light, making the cyclist visible from all angles. Probably the best commuter bike light of 2020 in our opinion! 

Cobber is designed to fit bars and seat posts 22 – 32mm+ diameter, and a large strap is also provided to fit tubes and head tube profiles with a circumference of up to 200mm.

It also comes with a Standard and Aero mount.
