【Smart Bike Radar Alert & Effortless Setup】RT02 bike radar tail light is equipped with a high-precision millimeter-wave radar, featuring a 54° wide-angle detection and 70m sensing range (the light automatically switches to high-brightness mode when a vehicle approaches from behind at 70m, flashes rapidly and emits an alarm when it gets within 10m), alerting following vehicles to provide cyclists with a safety warning. No apps or phone connection required—simply power on and go.
【Brake Sensing & Group Ride Mode】RT02 bike radar tail light has a built-in high-precision brake sensor that activates an ultra-bright red light during emergency braking; the smart radar filters out teammates moving at the same speed to prevent false alarms, making it ideal for group rides or races.

Up to 7.5 hours of runtime on a single charge. Type-C port supports fast, convenient charging.
