CatEye Sync Kinetic 40/50 LM Rear Light

Built for riders who want their rear light to respond as quickly as they do, the CatEye Sync Kinetic 40/50 LM Rear Light combines high-visibility output with smart, connected control. A permanent kinetic mode delivers a 50-lumen burst when braking or decelerating, helping you stand out at the moments when attention matters most.

Designed to work with the CatEye Sync system, it supports multi-light synchronisation and system monitoring via the app, making it easy to manage compatible lights with a single touch. Group ride-friendly modes help maintain visibility without distraction, while the compact, lightweight design and band mount suit everyday commuting as well as enthusiast riding. USB recharging keeps the setup simple for regular use, day or night.
