✔[Bicycle Radar for Rear Vehicle Detection] Bryton Gardia R300L is equipped with millimeter wave radar, which can detect the distance and speed of vehicles behind you. The detection distance is up to 190 meters. The vehicle information is transmitted via ANT+ or Bluetooth to your cycle computer or smartphone (using the Gardia app). Audio and graphic alerts are generated by the cycle computer to notify you of potential threats. ✔ [Bicycle Tail Light] The Brighton Guardia R300L features a bright 73-lumen bike taillight that's clearly visible even in daylight. This light uses Cree CREE_XPEBRD-L1 LED chips for brightness and reliability. It supports five flashing patterns, which can be selected manually or via your cycle computer. Additionally, the light automatically flashes when a vehicle is detected, alerting drivers of the bike's presence. This increased safety for both riders and drivers is a major benefit. The Guardia's built-in accelerometer also functions as a brake light, signaling following vehicles and fellow riders to slow down and helping prevent rear-end collisions. ✔ [Long Battery Life] The Gardia R300L's efficient radar power control ensures a long battery life. It lasts for 17 hours in daytime flashing mode and 12 hours in constant mode. The remaining battery life is easily checked via the cycling computer and app. The USB Type-C charging port ensures convenient everyday use. ✔[Wireless Connection] Gardia R300L is equipped with ANT+ and Bluetooth for radar and tail light connection. ANT+ protocol is standard, so it can be connected to cycle computers that support ANT+ radar and lights. Even if you don't have a cycle computer, you can still view rear vehicle information on your smartphone using the Bryton Gardia app. ✔[Warranty and Customer Support] Bryton is a Taiwanese brand that specializes in manufacturing GPS-based fitness devices.
