CatEye: SYNC Set Core & Kinetic Front & Rear Light Set


CatEye’s SYNC Set is a smart lighting system which is managed from a single switch on the front light. You can add up to seven lights and even synchronise the flash timing of rear lights for improved visibility to other vehicles on the road, day or night.

To inform those behind you when you are slowing down, the onboard accelerometer enables burst mode automatically to provide 50 lumens of brightness per rear light. This does not require unsightly cabling across your bike either, it’s all integrated.

To set-up your lighting system with your individual preferences, simply open up the CatEyeSYNC™ app. It also allows you to monitor power levels and connectivity, so you can remain confident that your rear lights are powered-up and active as you ride. The “Find Me” mode helps to identify which of multiple lights needs charging, which is really neat.

Recharging the Lithium-ion polymer rechargeable batteries is simple too: a Micro-USB cable is provided so you can top up any light from any conventional USB socket (USB 2.0, including battery packs). They have plenty of capacity, so most commuters can top-up weekly rather than daily.
