Such a great product!

I bought this light to increase my safety on my rides -- I have always had a tail light but none as bright nor capable of the wide angle of light one gets with these Cobbers. I was also happy to see minimalist packaging; I appreciate not creating more waste.

Yes all the reviews on this light are true. The fastening strap is no good… has already fallen off once. Battery life is also v average compared with my other comparable lights. For the price it’s no good.

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.
