A Quality Light

This rear light design gives good vision from a wide angle. The battery life covers more than most average ride times ie 4hrs and more, and the different pattern sequences for easy selection are effective. While both supplied bases are able to be securely attached to the bike frame, there is no adjustment for changing the light's attached angle to road.

Lasted a week

Rec'd a faulty unit - lasted a week.

An amazing rear light

As all Knog products, a very clever design combined with a solid built make an amazing product. As a Melburnian, it's even more of a reason to guy a Knog product. It's available in 3 sizes and the variety of modes is stunning.

Great So Far!

nice light. a bit hard at first to remove light from mount for charging but all worked out after a few tries. nice and bright, and shines nice in all backward directions.

Knog Cobbler rear light

This is a good rear light. When it is set on the 50 lumens setting it doesn’t show well in daylight but on the other two settings it’s great. Has good visibility from all rear angles

Knog Cobber

Brilliant light, fitted my aero seatpost really well had lots of comments how good it looks. However, my biggest gripe is recharging the light. The back of the light slides upwards to expose the USB port, this is an absolute nightmare to do as it sticks, even more so when there is road grime flicking up from the road surface. Still the best light I have used though, despite the moaning.

Perfect for aero seat posts

I’ve been looking for a rear light to use with my Bianchi Oltre XR1 and have not been able to find one that fits properly. I saw this and purchased it, and it is perfect. Fits the seat post, excellent light illumination, and fantastic light dispersion because of the curved lens. Highly recommended.
