The Lezyne Saddle AI Alert 250 Rear Light introduces the future of cycling safety technology. By combining artificial intelligence with our advanced ALERT taillight platform, it delivers the most precise and responsive cycling brake light on the market.

When a braking event is detected, the light instantly switches into Active Alert Mode, unleashing a powerful 250-lumen rapid flash that clearly signals deceleration. This intelligent system effectively communicates your movements to both motorists and fellow cyclists, dramatically enhancing visibility, awareness, and safety in all riding conditions.

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

The Saddle AI Alert 250 Rear is a premium saddle-mounted taillight that combines powerful visibility with next-generation AI Alert technology. Engineered for maximum safety, it utilizes 10 ultra-bright LEDs to deliver a beam pattern optimized for wide and even light dispersion, ensuring you remain highly visible in all riding conditions.

Its fully CNC-machined aluminum construction offers strength and durability, while Wide Angle Optics provide an impressive 270° of visibility. With seven versatile modes, the light ranges from the attention-grabbing 250-lumen Day Flash and Active Alert modes to the long-lasting FEMTO mode, delivering up to 60 hours of runtime.

Made to withstand the harshest conditions, it has been rigorously tested to IPX7 waterproofing standards, guaranteeing reliable performance in rain, mud, or road spray. A powerful 1100 mAh battery fuels the system, and recharging is simple—just unscrew the light from its saddle mount to access the USB-C charging port (cable not included).
