Big Cobber Front 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.
Big Cobber produces an incredible 330° of light, so you’ll be clearly seen from in front as well as from both sides. It’s brilliantly effective at attracting attention day and night, making it one of the safest front bike lights you could choose.

Customer Reviews
Big bright does its job
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 :-(
Bright and no issues. Charging system easy to use!
Very nice and bright. Would buy again
Absolutely love this front light, I’ve attached it to the upright section of my frame, below the handle bars, and it radiates white light a bit like a car’s day lights, not a harsh light, but is really comforting to use throughout my ride. I’ve purchased another one so I can swop over on rides over 35 miles. They are light weight and versatile fitting with a stretchy band. I also have the rear cobbers and feel more confident and visible from all angles on the road.
