Just buy separately

I’m returning and buying the big cobbler rear light as a standalone. The front makes you visible, but does nothing to light the road since it’s so disbursed. For the same price as a big cobbler front, I’ll buy a PWR light that both keeps me visible and actually lights the road in front of my bike. I give the rear 5/5 for both brightness and visibility, but front is a 1/5 for usability so I split the difference.

Hey Ryan, firstly, thank you for sticking with Knog! You're right of course, Cobber front lights are in our 'Be Seen' category, great for attracting attention day & night in urban environments where street lighting etc lights your path ahead. If you're looking to light up dark roads / trails, a Knog 'See By' light is the way to go. If you can't find a PWR front light (they've been discontinued), we've just launched a new Blinder collection (June '23) which comes with 600, 900 & 1300 lumen options. All the best!

Awesome lights

I started commuting by bike sixteen years ago and I’ve gone through a lot of lights and these, so far, are the best lights I’ve used.

'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.’

- bikeradar

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.
