The ROCKBROS SKL01 is a smart rear bicycle light designed to enhance visibility and safety for road, mountain, and urban cyclists. It features a COB LED paired with an anti-glare optical lens, ensuring a clear signal without blinding other road users. The light is housed in a 6061 aluminium alloy chassis, which keeps the device durable yet lightweight at only 55g. This model stands out with its intelligent sensors, including an integrated accelerometer for brake sensing and a light sensor that automatically toggles the power based on ambient brightness. It also detects vibrations and shocks to turn on or off automatically, reducing the need for manual operation. You can choose from several lighting modes, such as constant, rapid or slow flash, breathing, and SOS, to suit different riding conditions. Power is provided by a rechargeable 400mAh Li-ion battery that offers over 20 hours of runtime and is topped up via the included USB cable. To keep you informed, a battery indicator flashes every six seconds. The unit is IPX6 waterproof, making it reliable during heavy rain, and can be easily attached to your bike using the universal seat rail mount or the provided elastic band.
