It can accurately identify moving objects traveling at speeds between 5–120 km/h, automatically filtering out stationary or receding targets. It also supports simultaneous tracking of up to 8 vehicles. When a fast-approaching vehicle is detected, the tail light automatically switches to a high-frequency strobe mode to attract the attention of approaching drivers. Meanwhile, it connects to a bike computer or EFXLink via ANT+/Bluetooth, providing both visual cues and audible alerts to the rider for two-way warnings.

The RR01 integrates brake sensing functionality, automatically activating a high-intensity warning when decelerating to reduce the risk of rear-end collisions. It is equipped with side warning lights, offering a visibility angle of up to 270 degrees, and the tail light features four flashing modes that remain clearly visible from up to 200 meters away. Brightness can be adjusted via EFXLink, making it also suitable for group riding scenarios. With IPX6 waterproof rating and a USB Type-C charging design, the RR01 is built for extreme conditions and offers a battery life of up to 13 hours, ideal for long-distance rides.
