Great light ice to be more widely illuminated including sides

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.

Not bad

I had seen people running this light and loved how big and bright it was. In that regard, it doesn’t disappoint! However the battery life feels limited and removing and replacing the back cover is pretty fiddly—it takes a very specific touch, much like a sticky key—which is annoying. I love how safe I feel but there are big trade offs.

Rear light malfunctioned after little use

Bought the front and rear cobber when we bought our electric bikes. Used the lights on about five or six occasions and on the last attempt one of the rear lights didn’t work and on recharging just displayed a red light, but even after trying the 12 hour charge and holding down the button, the light remained dead. Contacted Knog but even with light just out of warranty, just an apology. For an expensive light…..? Other light still working well .

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.
