Great light, a miss on the attachment system

Great front light. Attachment system works well with small round tubes, but attachments don’t work well with modern frames. A new “clip” would be necessary.

Mixed feelings

I bought two Big Cobbers and I like its brightness, various modes and easy handling.
There are some drawbacks, though …
The shape is curved in a pretty narrow radius, which does not allow to mount it at the head tube. So I mount it on the left side of the fork (traffic is on the right side for us), which is a rather low position and visibility from the right is reduced.

Big Cobber’s modes can be adjusted via an app. This app is not available in the AppStore, so it is not checked by Apple and, therefore, I will not download it. What a shame, I would really like to use the feature.

Then, you need a special cable for loading the device which provide an USB-A socket that attaches to an USB-A plug on the device.
For may taste, "ordinary“ cables would do.

Would I buy Big Cobber again?
Probably not :-(

‘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 front bike light.

Simple Button

Big Cobber Front is simple to operate. A long press of the single button will turn the light on / off, and a short press will cycle through the 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, 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 handlebars 22 – 32mm+ and head tubes up to 200 mm in diameter. Also includes a standard and aero mount.

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.
