Introducing the Saddle Ai Alert 250 Rear, a cutting-edge rear bicycle light that blends smart technology with powerful performance to enhance safety and visibility like never before. At the heart of this innovation is Ai Alert technology—a next-generation system that uses Artificial Intelligence to detect braking and automatically switches the light into Active Alert mode. This high-visibility 250-lumen “brake light” effect alerts drivers, pedestrians, and fellow cyclists that you’re slowing down, making your intentions unmistakably clear. Designed to maximize safety and awareness, this is one of the most intelligent rear lights ever created for cycling.

Engineered for performance and durability, the Saddle Ai Alert 250 is built with a sleek, fully CNC-machined aluminum body. Not only does this enhance its strength and resilience, but it also contributes to its modern, premium aesthetic. Ten ultra-bright LEDs provide consistent and far-reaching light output, ensuring you remain visible in all riding conditions—from early morning commutes to low-light evening rides. With Wide Angle Optics, the light offers 270° of side visibility, significantly increasing your presence on the road from multiple angles.

The light comes pre-programmed with seven combined solid and flash output modes, giving you options tailored to different lighting environments. These include a disruptive Day Flash mode and a long-lasting Femto mode that can run for an impressive 60 hours on a single charge. The integrated 1100 mAh battery provides dependable power and recharges via USB-C (cable not included) for convenience and compatibility with modern charging setups.

Tested to IPX7 waterproofing standards, this rear light performs reliably in all weather conditions, from rain to road spray. Weighing just 73 grams and designed for saddle mounting, it remains compact and unobtrusive while delivering exceptional visibility. With its advanced Ai Alert brake-sensing system, robust construction, and long battery life, the Saddle Ai Alert 250 Rear is the ultimate taillight for cyclists who prioritize safety, style, and smart technology on every ride.
