Bike Radar Tail Light, 70M Vehicle Monitoring, Active alart in 10M & Brake Sensing, 800m Visibility, 6 Modes for Road/MTB Cycling Safety Light

【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. 【High Visibility & Adaptive Lighting & Long Battery Life】With 50-lumen brightness, RT02 bike radar tail light offers two main LED lighting modes plus multiple flash patterns (steady, fast/slow flash, breathing light, SOS) to ensure you’re clearly visible both day and night. Up to 7.5 hours of runtime on a single charge. Type-C port supports fast, convenient charging. 【IP64 Waterproof & Dual Mounting】Durable aluminum alloy + PC housing resists rain, dust, and impacts (IP64). Includes seat post and saddle rail mounts, fitting 99% of bikes for quick tool-free installation on road, mountain, or e-bikes. 【All-Weather Safety Upgrade】Integrates radar detection, sound alerts, brake warnings, and 800m visibility into one unit; an ideal choice for night riding, commuting, or travel.
