SIMPLE BUTTON
The Big Cobber is very easy to operate. A long press of a single button turns the light on and off, and a short press switches between modes. The Big Cobber light can last up to 120 hours.

SUPER LIGHT
The Big Cobber is 270 lumens and is really bright. The efficient COB (Chip on Board) LEDs ensure maximum brightness levels for up to 90% of battery life. The Big Cobber comes with 8 pre-programmed modes and is also compatible with the ModeMaker app so you can customize the lighting modes.

EASY ASSEMBLY
The Cobber comes with tool-free removable silicone straps for 22-32mm+ diameter tubes and seatposts and a magnetic mount. There is also a large strap that fits tubes and head tube profiles up to 200mm in circumference. The Cobber comes with standard and Aero mounts.

INTEGRATED USB CONNECTOR
The Cobber does not require a charging cable, as it has an integrated USB port that plugs directly into USB ports. Charging time is 5.5 hours. When the battery in the Cobber is low, a red ring will light up around the button. This ring will turn green and then turn off when the Cobber is fully charged and ready to use.
