Introducing the future of bicycle light technology- Ai Alert. Combining Artificial Intelligence with our advanced ALERT rear taillights to bring you the most accurate cycling brake light on the market. The light automatically detects brake events and intelligently changes output mode to Active Alert - a rapid 250-lumen flash “brake light” mode; signaling deceleration, effectively communicating your actions to traffic and fellow cyclists, enhancing rider visibility and safety.

*Ai Alert lights come pre-programmed and do not collect rider data.

The Saddle Ai Alert 250 Rear is a premium, highly visible saddle-mounted rear taillight combined with advanced Ai Alert technology. Equipped with 10 super-bright LEDs providing a beam pattern optimal for light dispersion in even the most challenging conditions. The fully CNC-machined aluminum construction with wide angle optics for 270° of visibility, offers 7 combined solid and flash output modes- from the eye-catching max 250 lumens emitted in both Active Alert and Day Flash modes to the impressive 60 hours of runtime in FEMTO mode. Rigorously tested to IPX7 Waterproofing standards to ensure functionality in the toughest weather conditions. The Saddle Ai Alert 250 Rear features an 1100 mAh battery capacity. Simply unscrew the light from the saddle-mounted body to easily detach for quick and easy USB-C charging accessibility (cable not included).
