Started with one, now the whole family has them

I have found Knog lights to be some of the most durable and useable lights I have used in many years of riding. The Mid Cobber is then one of the best rear lights in the Knog range in terms of size, visibility, patterns etc. The fitting options are great including the one for an aero seatpost.

Two cobber in the row with malfunction: button gets stuck after riding damp condition

The first one failed after a ride while the ground was damp. I thought I just got unlucky.

Got it replaced. Today after a ride in similar condition (wet ground, not raining) the exact same thing happened.

I think the design on these cobber is questionable, they do not like wet ground :/

Faulty ! Very Disappointed !!

Bought 2 rear Cobber lights -- one just stopped working, have purchased many of the KNOG products over the years ... quality control and after sales is slipping -- I won buy them again as outlay cost does not represent reasonable length of service UNIMPRESSED!

Light is big, bright, and the 180 degrees of light are visible from the side.
Sliding the light into the mounting bracket is a bit difficult.
The USB plug looks like it is vulnerable to damage.

'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.
