Knog Cobber: Best rear bike light on the market?

January 25, 2024

Knog Cobber rear bike light

We've tested a fair few cycle lights over the years. The Knog Cobber is our favourite.

As with most bike lights, there's dizzying choice of lighting patterns, but we found ourselves sticking with the bog-standard steady light setting.

Standing 93mm tall and belting out up to 470 lumens, the distinctive wrap-round design throws its beam across a wide 330°. And when you get home, an integrated USB charging pin does away with the need for a charging cable.

All in all, arguably the best all-round rear light on the market.
