The ROCKBROS 24520007001 is a smart rear bicycle light designed to enhance your safety during urban commutes or road and mountain biking. It features high-intensity LEDs that provide a wide-angle beam, ensuring you remain visible to other road users throughout the day and night. This light simplifies your ride with an integrated brake sensor that automatically increases brightness when it detects deceleration, alerting drivers behind you. To save energy, it uses light and motion sensors to activate automatically in low-light conditions and turn off after a period of inactivity. The IPX6 water resistance rating means the durable housing can withstand rain and splashes without compromising performance. Weighing only 26 g, the device is lightweight and attaches securely via a stable mounting system. It is powered by a USB rechargeable battery, removing the need for disposable cells and making it easy to top up between trips.
