The ROCKBROS R0 Roll Over is a smart handlebar end light designed to increase your visibility and safety on the road. Built from durable ABS plastic, this lightweight 30g accessory fits onto 22 mm handlebars using the included hex-key mountable bar plugs. It features high-brightness LED beads with an IPX6 waterproof rating, ensuring it remains functional even during heavy rain. You can choose between several lighting modes to suit your environment, including fast flash and breathing effects, while the steady mode allows you to adjust brightness between high, medium, and low settings via a long press. The battery is conveniently recharged through USB-C, offering varying runtimes from 7.5 hours in steady mode up to 213 hours in high frequency mode. To make your ride safer, the light includes brake-sensing technology that triggers a brighter signal for three seconds during deceleration and an auto-wake function that activates the light upon motion before entering sleep mode after 30 seconds of inactivity. For those riding in groups, the Team Sync feature allows multiple lights to synchronize their patterns, with the green mode reaching up to 30 meters and the blue mode working within 2 meters.
