Why We Love It
When you're riding before sunrise or commuting through traffic, being seen is just as important as seeing the road ahead. The Knog Cobber Reflex Rear Bike Light takes visibility to another level with intelligent technology that reacts to your riding. It automatically adjusts its light output as you brake, corner, and change speed, helping you stay more visible when it matters most.
Talk Nerdy To Me
The Cobber Reflex Rear Light features Adaptive Reflex Technology, using built-in sensors to detect bike speed, lean angle, and deceleration. During braking, the light automatically increases brightness to alert riders and vehicles behind you. When cornering, the light pattern adapts to your bike's lean angle, improving visibility through turns.
Producing up to 250 lumens with a wide 330-degree beam, the Cobber Reflex can be seen from multiple angles, making it ideal for busy roads and low-light conditions. Eight lighting modes come preloaded, with additional customisation available through Knog's ModeMaker 2.0 software via USB-C. The integrated quick-release mount fits both standard and aero seatposts, while the IP67 waterproof rating ensures dependable performance in wet weather.
