The ROCKBROS AI Q5 Mini is a smart rear bicycle tail light designed to enhance your visibility and safety on the road. It features an aluminum alloy body that houses high-intensity LEDs, offering between 5 and 8 different brightness levels along with various constant and flashing patterns to suit different lighting conditions. This light simplifies your ride with auto on/off functionality and a smart brake sensing system that automatically increases brightness when you slow down, alerting drivers behind you. Its IPX6 waterproof rating ensures it continues to operate reliably during heavy rain or splashes, while the USB Type-C port allows for convenient recharging. Designed for road, MTB, and city bikes, it comes with a secure seatpost mount that keeps the unit stable during movement. The package includes everything you need to get started: the tail light itself, the mounting bracket, and a charging cable.
