Knog Big Cobber Rear

Most standard rear lights only project light directly backward. The Big Cobber wraps around the sides of the unit, allowing drivers approaching from side angles to see you much earlier, which significantly increases your safety at intersections and roundabouts.

Correct. The light features an integrated USB male plug, so you can plug the unit directly into any standard USB-A port on a computer, wall adapter, or power bank. It eliminates the need to keep track of proprietary charging cables.

Yes, the Big Cobber includes an Aero Mount specifically designed to fit non-round, aerodynamic seat posts. It also comes with flexible silicone straps for standard round seat posts up to 32mm+ in diameter.

Modemaker allows you to connect the light to your computer and customize the flash patterns and brightness levels of each mode. You can essentially tailor the light's behavior to your specific riding environment, such as prioritizing battery life for long commutes or high-visibility strobes for busy city traffic.

Yes, the unit is rated 100% waterproof. You can ride through heavy downpours, puddles, and mud without worrying about the internal electronics, as the design is fully sealed against the elements.

COB LEDs are highly efficient and produce a dense, uniform light rather than a single pinpoint beam. This technology allows the Big Cobber to maintain maximum brightness for up to 90% of the battery life, so your light won't dim significantly as the battery drains.
