With its cutting-edge radar technology, SEEMEE R300 is not just a rear light but a true active safety system. It detects approaching vehicles up to 140 meters away, at speeds from 10 to 160 km/h. This proactive monitoring drastically reduces the risk of rear collisions, whether from fast-moving vehicles, e-bikes, or occasional cyclists. When vehicles come within 50 meters, SEEMEE R300 immediately emits a 300-lumen warning light, dimming and slowing it as they get closer. This ensures high visibility while remaining considerate of both pedestrians and drivers. SEEMEE R300 integrates seamlessly with major cycling computers like Garmin, Wahoo, and Hammerhead, providing instant traffic updates. Our pioneering PelotonSync Flash technology, designed for group rides, intuitively synchronizes the flash among compatible nearby devices, enhancing group safety. SEEMEE R300 features a powerful 3350 mAh battery, offering up to 100 hours of runtime. The eco-flash mode extends battery life without compromising the device’s safety features.
