Staying visible on the road is one of the most important things a cyclist can do, and this rear light takes that seriously. With a 330-degree beam angle, it throws light behind you and out to both sides, meaning drivers approaching from an angle or pulling out of side streets can see you clearly, not just the car directly behind. Whether you’re commuting through city traffic, doing early morning training rides, or heading home after dark, that kind of all-around visibility makes a real difference to your safety on the bike.

One of the standout features here is how long the light actually lasts between charges. The Chip on Board (COB) LED technology keeps brightness at its maximum level for around 90% of the battery life, so you’re not gradually fading into the background as the ride goes on. At up to 70 hours on the steady mode, this is a light you can charge once and largely forget about for weeks of regular riding. And when you do need to charge it, it’s a straightforward USB connection. The single button operation is refreshingly no-fuss too: long press to turn it on or off, short press to cycle through modes. No fumbling around with complicated controls mid-ride.

For riders who like to fine-tune their setup, the Knog Modemaker app lets you customise the light modes to suit your riding conditions. It mounts quickly and easily using silicone straps that fit standard and aero bars from 22mm upwards, as well as head tubes up to 200mm, and the quick-release mount means it’s off the bike in seconds when you lock up. With an IP67 waterproof rating, it handles rain and puddle spray without any fuss. Compact enough to barely notice on the bike, but bright enough to make sure everyone else notices you.
