Lil Cobber

Pleasantly surprised. For such a small size brighter than expected.

Good Lil'Cobber

This light rules! Tucked away under my saddle on the seatpost, just blinking away. Lots of different modes of flash, good battery life, and a good mounting system. I have no complaints, does what a good tail light should do, and the design is awesome.

Good light, the mount is a bit flimsy though.

Light is great, super bright, has enough modes and the side coverage is awesome. The mount works, but it's a bit clunky mounting / unmounting the light. Not super positive when it's locked in, and awkward to remove. Feels like the light will outlast the mount. Another mounting option would be great.

Great bike light

I just wish it had some of the same modes as the bigger ones.

Superb Light

Quite superb light which really does give everyone no reason whatsoever for not seeing you! It has fabulous mounting bracket. There is a huge variety of light modes and most of them can also be tailored for individual preference but it would be helpful if all of them showed their runtime on the app but I understand that Knog are working on this - it will be very helpful. Yes, it's expensive but you actually do get what you pay for in this case. I'm thrilled with mine.

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

Why you'll love riding with Lil Cobber.

The world's only 330 degree rear bike light.

Simple Button

Lil 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 40 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 5 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 Lil 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.
