The CatEye Sync Kinetic Rear Light is a smart, high-visibility rear light that responds in real time to your riding. Its permanent kinetic mode triggers a 50-lumen burst during braking or deceleration, increasing visibility exactly when its needed most. Designed for the SYNC system, it enables seamless multi-light synchronization, app-based monitoring, and group ride-friendly modes all in a compact, USB-rechargeable design. CatEye SYNC provides a faster, easier, and safer lighting solution for all riders, from commuters to enthusiasts. Multiple lights can be wirelessly controlled and monitored with a single touch, delivering full 360-degree visibility day or night.
