Knog Cobber Reflex Bike Light

The light uses built-in sensors to detect your speed and bike lean. When you slow down or stop, it automatically increases its brightness to alert drivers behind you, similar to a car's brake light.

Yes, the included quick-release mount is designed to be compatible with both standard round seatposts and aero-profile posts, ensuring a secure fit regardless of your bike frame's shape.

Absolutely. Because the LEDs wrap around the sides of the light, you get significant visibility from the side, which is crucial when approaching intersections or navigating roundabouts where drivers might be coming from an angle.

You can connect the light to your computer via USB-C and use Knog's web-based interface, ModeMaker. This allows you to drag and drop your preferred modes and adjust their brightness or flash patterns to suit your specific riding needs.

Yes, the light has an IP67 water resistance rating, meaning it is fully protected against dust and can withstand immersion in water up to one meter deep for 30 minutes. It is built to handle heavy downpours and road spray without issue.

The battery life varies depending on the mode you choose, but it can last up to 70 hours on the most efficient settings. For daily commuting, you will likely only need to recharge it once every few weeks.
