Best, brightest, safest light

I've used this as my rear visibility light for over two years now. It is unbelievably bright and has the unique advantage of being visible from the sides as well. I still haven't come across a product that competes. I use this to commute in dangerous road conditions at night, and the passing cars always stay nice and far away! There's a great full brightness, low frequency blink setting-- it can still last for hours at this setting even though it is very, very bright. Awesome customer service from Knog also!!!

Bright and multi-angled

I really like this light. It’s very bright and allows motorists from the side to see you as well. Its crescent shape fits my seat post perfectly. My only gripe is the lack of a “fully charged” indicator.

Hey Andrew, when charging, the light around the button should turn green when fully charged. See 1 min, 25 sec in this User Guide video - https://www.youtube.com/watch?v=BuXEPnr8oVI.

2nd Cobber is Great so Far

This is my 2nd mid-size Cobber. I love the brightness and the wide angle. I feel safely seen. Unfortunately my first one had its charging prong break in the USB cord. My second Cobber is working well so far and I am taking care in plugging it in.

'purposefully designed to demand attention from all angles. Ride confidently with Cobber.'

‘Knog’s Cobber Mid is an impressive light with a simple and elegant design.’

Why you'll love riding with Mid Cobber.

The world's only 330 degree rear bike light.

Simple Button

Mid Cobber Rear is simple to operate. A long press of the single button will turn the light on and off, and a short press will cycle through the modes. Cobber has a run time of up 100 hours.

Packed With Innovation

Efficient Chip on Board (COB) LEDs provide maximum brightness level for up to 90% of the battery burn time. As well as 8 pre-programmed modes, it’s also compatible with Knog's ModeMaker app so you can customize your light modes.

Mount With Ease

Cobber comes with tool-less removable silicone straps for bars and seat posts 22 – 32mm+ diameter and a magnetic mount. Cobber comes with a standard and Aero mount.

Integrated USB Connector

You can plug Mid Cobber directly into USB-A ports, meaning no cables. Ever. When your Cobber is running low on battery, a red ring will light up around the button. This ring will turn green and then turn off once the Cobber is fully charged.
