The KNOG Mid Cobber is a compact, USB-rechargeable rear bike light that delivers 170 lumens and a 330° beam for high-visibility day and night riding.

Designed to make you more visible from behind and from the sides, the Mid Cobber blends bright output, long runtime and flexible mounting into a single, tool-free package. It pairs simple one-button control with app-based customization and multiple mounts so you can move it between bikes, bags or helmets. The light is built to handle wet weather and everyday knocks, making it a practical safety upgrade for commuters, roadies and casual riders alike.

How bright and wide is the light, really?

The Mid Cobber outputs 170 lumens and creates a broad 330° beam, increasing the chance that approaching traffic will spot you from behind and at an angle. Its multi-LED layout focuses attention without producing a harsh glare for other road users.

• 170 lumens peak brightness for day and night visibility.
• 330° beam angle reduces blind spots to the sides.
• Multi-LED array balances intensity and spread.

What mounting options does it offer and how easy is installation?

KNOG engineered the Mid Cobber for swift, tool-free attachment. Included silicone straps suit 22–32mm round posts, while a magnetic quick-release and an aero mount provide neat fits for modern seatposts and aero rails.

• Removable silicone straps for standard round seatposts and seat rails.
• Magnetic quick-mount for fast on/off convenience.
• Aero-specific bracket to align with streamlined seatpost profiles.

How long will the battery last and how do you recharge it?

• Up to 100 hours runtime on low-power modes.
• Integrated USB-A plug for simple charging from any USB port.
• Battery status indicator shows remaining charge at a glance.
