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
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.
Super wide visibility. Feels great for knowing cars will see you
I love the way the light fits on the front stem of my folding bike. It takes up less space than other designs would. The light is bright and the customizable settings via the app are useful. However, the rubber band broke after just a few days in the cold weather. It would be nice if there were another way to strap it on (I improvised something new, but a simple velcro or thicker rubber strap would have been better than the band included, I think). Also the charging male USB connector sticking out of the light seems fragile. When I take the light off of the bike, leaving the clip on the bike, it would be nice if the USB connector weren’t sticking out to be broken off easily. I have to be very careful with it, and this just seems an odd design choice. Overall a bit odd, and rather expensive, but quite a nice light.
