Good light. My only criticism is the absolute lack of instructions on how to get the clip off the light for the first time. Also, the light arrived dead which isn’t the end of the world but sorta annoying.

Excellent idea, things to improve

I use this device to be seen by others by night, it works very well.

The button to start the device is way to small (impossible to use it with gloves).

I only use one pattern (low), I wish I could get rid of those i don't use. (I tried to in the PC application but I didn't succeeded).

The autonomy is not long enough (five hours in low mode when weather is not cold)....it should be doubled.

The "attach system" should be "Garmin compatible".

Thank you
Thomas Pasteris.

Feel so much safer

I cycle to work everyday on busy CBD roads in Melbourne, with plenty of intersections on the way. Although I’ve always had two lights on the front (helmet using mini blinder, and one on the handlebars), somehow I still worried when approaching bigger intersections that cars would be too focused on the cars to see me. I feel so much safer with this light on. As it advertises, the wrap-around nature of the light really helps to be seen from a range of angles - which is a great comfort at intersections. Super bright too!

I just about get away with one charge a week (2.5hours) on a mix of flashing modes, which for me is fair. Easy to charge and comes with a cable rather than only direct to usb.

Great light, great product. I think everyone should have one!

‘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 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.
