Description
The Art of Being Seen
Introducing the future of bike light technology — the Lezyne Saddle AI Alert 250, combining Artificial Intelligence with the advanced ALERT rear taillight 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.
Note: Ai Alert lights come pre-programmed and do not collect rider data.
Engineered Precision
The fully CNC-machined aluminum construction with 10 super-bright LEDs and 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).

Very bright

A very bright under seat light. It tucks under the seat well, but is very visible to anyone behind. Good battery life. Has several settings. No complaints!

Mounted this under the back seat of my road bike- easy to do.
Charges quickly and holds charge for hours when in use.
I like the different strobe modes and it's bright.

Smart light, super bright, & compact. BUT, Saddle bag won't fit with saddle mount. Also T25 cannot fit with Selle Italia Turbo Boost saddle.
