KNOG COBBER REFLEX Rear Light
Unable to load collection availability
Description
The Knog Cobber Reflex rear light adapts to the road: its intelligent Reflex modes respond to the bike’s speed and lean to maximise visibility when it matters most. With 250 lumens spread across a 330° arc, it provides a strong presence from behind and from the sides.
Brake mode is this light’s standout feature: it automatically brightens as soon as the Cobber detects the bike slowing down — a clear braking signal for vehicles behind, with no action needed from the rider. Tilt mode complements it by flashing in the direction of the bike’s lean when cornering.
Rechargeable via USB-C, with an IP67 waterproof rating and a built-in low-battery indicator. The robust quick-release mount fits standard and aero seatposts, using medical-grade silicone straps in three sizes (22 to 32 mm and above). Weight: 39 g. Up to 70 hours of battery life in Eco mode.
