Design & Tech

Awesome rear light

I decided it was time to upgrade from my Knog Blinder Mr Chips (a great light) so I was highly visible to drivers whilst riding in inner city. Big Cobber is an awesome product - 270 lumens and curved design really stands out. When driving I see too many cyclists with inadequate rear lights - not me!

Excellent product...........I am a long time bike riding tail light collector and rejector........this is by far the best one I have used

A great rear light!

This light is bright and charge lasts a long time. Easy to attach to the bike.

Big Cobber ... clobbers all other tail lights!

What an outstanding light! I am scared to put it on "full-blast" mode for fear of upsetting motorists. I feel so safe and the many modes are excellent. Worth every cent! thanks KNOG

Great bright light

Very impressed with this light. Many modes but most importantly very bright so you can be seen for 1km.

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.
