The Knog Mid Cobber rear bike light is built to keep you visible from more angles, not just directly behind. Its unique wrap-around beam pushes light out to the sides, helping drivers notice you sooner at intersections, roundabouts, and busy urban roads. If you want a rear bike light that focuses on real-world safety, this one stands out.

Where this light really earns its place is in stop-start traffic, commuting, and shared paths where cars approach from different directions. The wide beam pattern reduces blind spots around your bike, so you are not relying on a narrow rear beam alone. It is the kind of upgrade riders notice immediately once they start using it.

Who is this rear bike light for?

Ideal for riders who commute in traffic, ride at dawn or dusk, or want stronger side visibility for safer road positioning. It suits road cyclists, commuters, and urban riders who want to be seen clearly from multiple angles, not just from directly behind.

Who is this not for?

This is not the best choice if you only ride off-road where side visibility is less important, or if you want a very small, basic backup light. Riders looking for a simple low-cost rear blinker may find this more advanced than they need.

Why we love it

We have found the wrap-around beam makes a genuine difference in real traffic, especially at intersections where standard rear lights can disappear from side view. Our favourite part is how evenly the light spreads without harsh hotspots.

Hot tip!

For maximum safety, use the steady pulse mode during commuting. It stays bright enough to stay visible while still giving strong battery life for regular daily rides.
