Great Light.

Great bright light, the only light you’ll ever need. Attached to bike very easily, charges easily as well. Definitely worth considering.

Love this light!!

This is the best light I've owned! So bright and I feel safer at night knowing others can see me from all angles, especially on roundabouts. Took note of other comments about them coming loose and seen a couple of people that have lost them... easy fix... I use a thin velcro strip that goes around the centre of the light and seat post. Can't go anywhere! I think the only thing I would change on this is the mount, and I'd love to see other mounting options for it.

Let your light shine

This light has blinked happily on the back of my bike though city commuters and country backroads. Many people have commented on it… its very visible from the back and the side. So easy to charge just plug into a USB port no cables to find/ loose /remember. Amazing to be able to choose your own flashing sequence through the app. Great Aussie product.

'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.
