CatEye VIZ 100 Rear Bike Light

Built for everyday riding, the CatEye VIZ 100 Rear Bike Light delivers compact, high-visibility illumination for commuting, group rides and after-dark journeys. Using 3 high-brightness LEDs with up to 100 lumens output, it’s designed to help you stay noticed in changing conditions, including daylight thanks to its Daytime Hyperflash mode.

For added awareness from multiple angles, the VIZ 100 offers 300° side visibility alongside extended rear beam projection, supported by CatEye’s OptiCube lens technology to maximise light spread. Recharging is straightforward via USB-C (cable not included), while smart battery features help keep you visible on the move, including an auto-save function that switches to flashing when power is low. A low battery indicator, mode memory and an SP-15 Snap System mount for aero seatposts complete a rear light that’s easy to live with on regular rides.
