The Best There Is

Can’t say enough good things about this light. Been using it regularly for over two years and not a single issue. The throw this thing has is insane, the light practically surrounds your rear wheel. At night I like the flow from side to side function. It really catches the eye, and makes you stand out from a typical stagnate blink, which is huge for being seen when it’s dark. If I’m running it as a daytime light the normal blink is best in my opinion, and does that just as well as any other light out there, again with the added degrees of visibility.

I was skeptical of the charging situation at first, especially when it got covered in mud or road grime, but it recharges no problem. I love how simple it is to take on/off with just a quick hit up and it pops off, and the mount is so small it’s invisible when riding without the light. I hope Knog doesn’t ruin a good thing. This is truly the most unique rear light on the market, and by far the best. Knog really broke my heart when they killed off the PWR, I sure hope the Cobber doesn’t end up with a similar fate.

Inconsistent electronics

I would love to give these lights a better rating but after years of commuting use and many replacements I can’t continue to use Knog lights. They are beautifully designed and provide the best visibility but almost like clockwork each light has died around 1 1/2 years of use which for a nearly $100 light is not acceptable. Knog has always stepped up on the warranty but still for the price I would expect more.

A light that gets attention

This is the third mid cobber rear bike light that I have gotten. It is bright enough to be seen during the day. And I often get compliments while I am out riding in vents such as Bike MS or the Triple Bypass.

Good light but falls short large Cobber

I like the light. I bought 4-5 of the large Cobber but they don’t sell them anymore. I found the mid to be a good light but more difficult to attach.

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

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.
