Big cobbler light pack

Love the Brightness of both lights. Love the custom light setting feature. Concerned about losing the lights going over gravel bumps off road !

5 star light b/w 1 star mount

It’s been a couple years (maybe a bit less) that I’ve had these lights and the performance of them is just perfect. I love the functionality of the lights. The build quality is so frustrating, though. The bracket is stiff plastic that won’t conform to my head tube so the front light rattles around over every tiny bump. The ever-so-tiny fins on the light that attach to the bracket are super thin and brittle and will break when trying to put on or take off the light. The male USB plug is also fixed in position, with the same brittle, thin plastic, and they break as well. However, like the other reviewer stated, there's no better lights in existence so I have also purchased a second set after the first set broke. If they would only create a rubberized, flexible mount (like just about every other light they make) and incorporate a USB C slot to charge, these would be flawless. Well, until the rubber mount broke (like all their other lights haha).

Great light, but terrible attachment

Light itself is fantastic, but the attachment mechanism sucks. It does not click in while the attachment is on the bike, the only way is to take the whole thing off, every time it needs to be charged. Very annoying, but light is so good, that I still bought another set.

'this is simply the best bike light set for attracting the attention of other road users.'

‘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 bike light.

Simple Button

Big Cobber bike lights are simple to operate. A long press of the single button will turn the lights on / off, and a short press will cycle through their modes.

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, both are compatible with Knog's ModeMaker app so you can customize light modes.

Mount With Ease

Cobber comes with removable silicone straps for handlebars / seat posts 22 – 32mm+ and head tubes up to 200 mm in diameter. Aero & standard mounts included.

Integrated USB Connector

Big Cobber plugs 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, then off once fully charged.
