So sad, I lost it

As soon as I received it, I turned it on and went on my bike to try out! The light is super bright, all I was looking for! Next day went exploring with my husband in the woods and had to ride with the mtb on couples miles on the road before hitting the trails. So I put the light on so the cars can sees us. Once in the trail I forgot to take it off. We were exploring off trails and when we finally got back to the gravel road I checked my lights and it fell somewhere. I was sad. Because it’s not a trail that you follow I couldn’t go back to retrieve it. I’ll get a new one for sure, but I’ll
Wait for some discounts.

'Big Cobber is hands down the best bike light for attracting attention from the rear.'

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

Why you'll love riding with Big Cobber.

The world's only 330 degree rear bike light.

Simple Button

Big 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 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 seat posts 22 – 32mm+ diameter and a magnetic mount. Also includes a standard and Aero mount.

Integrated USB Connector

Plug Big Cobber directly into USB-A ports. 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.
