The ROCKBROS Q1 MAX is a smart brake taillight designed to increase rider visibility through intelligent lighting. Its housing is crafted from CNC-machined aluminum alloy with a PC optical lens, ensuring a durable build that can withstand rain and bike washing. The device features a built-in sensor that automatically detects braking or deceleration, boosting the light's brightness for 2.5 seconds to alert following traffic. This light offers both smart auto and manual modes, allowing it to turn on or off based on ambient light levels and vibration. To conserve energy, it enters a sleep mode after 30 seconds of inactivity or during bright daylight, waking up instantly when it senses movement or a drop in light. You can easily switch between five distinct lighting modes using a single button, while four blue LED indicators keep you informed about the remaining battery level. Charging is handled via a USB Type-C port, compatible with power banks or computers. For installation, the package includes both a saddle rail mount and a seatpost mount, along with an elastic rubber strap that fits both round and aero seatposts. Weighing approximately 0.3 kg, this setup provides a versatile safety solution for cyclists who want a responsive light that adapts to their riding conditions.
