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.

Cobber Quick Start - English

This compact rear bike light delivers exceptional brightness, with customers saying it's "crazy bright" and provides "excellent side visibility." Features include integrated USB charging and battery indicator. Most praised its small size, long battery life, and "great value." However, one shopper experienced durability issues with the mount breaking after less than a year of use.

Crazy bright, can't even look at it. No way someone is going to miss me on the road. Perfect!
Very bright despite being small. Excellent side visibility.
Well impressed with the design and functionality. Battery indicator takes the guess work out.

Durability sucks

Used this less than a year. While holding the bracket to the mount to get the light off, the mount broke one of the tabs off. The bracket is thin and not durable at all. No replacement mount so it appears the light is worthless now. The plastic slides into the mount and held by an unnecessary magnet.

I expected better quality.

I loved this light, but after about 3 years it stopped working. The button no longer responds.

Lil Cobbler

It met and exceeded my expectations, great illumination!!!!

Crazy bright, can’t even look at it to change the functions. There’s absolutely no way someone is going to miss me on the road. Perfect!

Lil cobbler is a ripper

Site perfectly below the dropper post on MTB for our weekly night rides in the bush.

Lights for rollator

I attached the lil cobber to my trionic walker rollator, so i have two position lights (left & right).
Useful when crossing the street in low light (winter) or walking in a big crowd.
The large angle of light makes me visible from everwhere.

Great light and arrived super quick

lil cobbler

Easy fitting , secure and bright

Lil Cobber Rear Bike Light

Nine light.

Awesome little guy

Very bright despite being small. Excellent side visibility. Fits on the rear seatpost of my vintage road bike, which lacks the clearance for lights that are much larger.

Form & Function

Well impressed with the design and functionality of the Lil Cobber. Mounted on my seat tube in seconds and am impressed with the brightness and field of view of the light. Clever integrated USB (male) adaptor completes the fantastic design. Convenient battery indicator takes the guess work and has never left me short on power. Battery life seems inline with company estimates. Not an issue, but I couldn’t get it to charge using a normal Apple USB wall charger for some reason. No problem using my laptop or an Anker battery charger. Would definitely recommend.

lill cobber rear light

love that there are so many options for battery saving. Would like a saddle bag mount- but made it work.

Great, but what about usb-c??

Great, but what about usb-c?? We are in the 2023, where you find a macbook with usb-a to shoot a promo?)

Great light.

Bought the backlight for me and my kids (6 and 2,5 years old).
I like the the outstanding battery life and good angle of lightened field

Best brake light ever!

Great product! Easy to use and small and compact

Best lights

I have tried many lights for my bike, and Knog are my brand of choice. They keep going for hours on those really long bike rides, are bright, easy and quick to charge, don't have bits that fall off and cope in the rain. Great lights for any type of bike rider.

little Cobber shines Big

brightest rear light I've had. everyone says how well it illuminates my rear…..well the rear of my bike actually! Only criticism…..it slides off a little too easily.

Perfect little light

Compact, bright and surprisingly long battery life. Love that no cables are required to charge it.

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.
