Effective for on-street commuting

I already feel like cars are giving me more space on shared roadways and bike lanes. I'm using the rolling flash for night riding.

Feel safer on the road now!

Okay, so I've had this light for a week now and have identified the good and poorer points. As far as the function of having a rear light - to be seen and noticeable, it ticks every box going! From the very first use I've noticed that cars no longer swoop around me, EVERY car has given me lots of space. I think the light confuses them and they avoid me/it, which is perfect.
The area that I'm concerned about, is how unstable the clip feels against the seat post - despite having the tightest band in place, the clip wobbles, and so this transfers into the light wobbling even MORE. I'm nervous on how rattly the light is and fear that it might jump out of the clip, as its only held down by a magnet. Also, my seat post isn't straight up, it leans back slightly, so the light, held against the seat post, points slightly downwards and not entirely to the rear, as I'd prefer.
Okay, well, it's early days and we'll see how we get on.

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.
