Mid Cobber Rear Bike Light
Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.
Mid Cobber produces an incredible 330° of light, so you’ll be clearly seen from behind as well as from both sides. It’s brilliantly effective at attracting attention day and night, making it one of the safest rear bike lights you could choose.

Excellent light. Perfect and visible from a great distance!
Awesome design and functionality. Knog have got this one right. Extremely bright, visible from the side, easy to operate with gloves on, good battery power. Ten out of ten.
Pretty good rear bike light.
PRO: Nice and bright. Lots of blinking choices.
CON: Charge does not last very long. Tricky to mount and dismount from its holder.
Works well, and has a good variety of light modes to suit various light conditions. Eco flash is bright enough to stand out during daytime on overcast/rainy days. Side visibility is important, which this design accommodates well.
Won't fit beneath the seat if the seat is lowered too far due to the height of the light.
Nice bright light with a range of flash patterns. Excellent side visibility. I've owned knog lights in the past and been extremely disappoint with the band designs that broke and were impossible to fix, this is no longer an issue the cobber features a neat little bracket mount that uses regular black o-ring bands, perfect.
