The Cobber Reflex Rear is engineered for high visibility in all directions, emitting 300 lumens of light with 170º coverage to ensure riders stay seen from behind and the sides. With a range of modes, USB-C recharging, and IP67 waterproofing, it’s built for consistency and confidence in any conditions. Featuring our revolutionary Reflex technology, The Cobber Reflex provides users with reflexive lighting modes that adapt to their riding conditions. Programmed off of thousands of collected GPS data readings and feature auto-on/auto-off modes, motion-activated deceleration modes, and a dynamic tilt mode, all of which help improve rider safety by signalling to vehicles of changes in the road or riders speed for a safer ride.

Back in 2002 two friends – Hugo Davidson and Mal McKechnie – had an idea. That idea led to Knog, a bike lights and accessories brand that really takes the idea of form meeting function and has changed the entire bike lights and accessories space.
In 2008 Knog introduced the world’s first silicone bike light in the Frog. What the Frog did was remove the need for a light and a separate mount, instead housing the light components in a flexible silicone housing that acted as its own mount and could be moved on and off the bike incredibly easily – as well as looking pretty cool at the same time as it could be made in a whole cornucopia of different colours. That one light has gone on to sell over 7 million units worldwide and counting.
