The future of bike light technology - Ai Alert

By combining artificial intelligence with Lezyne's advanced ALERT rear lights, you get the most precise bike brake light on the market. The light automatically detects braking and intelligently switches to Active Alert mode - a fast 150 lumen strobe light that signals deceleration. This informs traffic and other cyclists of your actions and increases the rider's visibility and safety.

The KTV Pro+ Ai Alert Rear is a high quality, high visibility rear light combined with advanced Ai Alert technology. Equipped with super bright LEDs that produce an optimal light pattern even in the most difficult conditions. The lightweight and robust co-molded construction with wide-angle optics for 270° visibility offers 6 combined fixed and strobe light modes - from the max. 150 lumens in Active Alert and Day Flash mode to the impressive 20 hours runtime in FEMTO mode.

A versatile silicone rubber mounting strap can be attached to aero or round seat posts. Rigorously tested to IPX7 waterproof standards to ensure functionality in the harshest weather conditions. The rear bike light also has a 400 mAh rechargeable battery and an integrated USB stick allows for convenient charging without a cable. Experience the next generation of bicycle lighting for safety and visibility with the advanced Ai Alert technology of the KTV Pro+ Ai Alert Rear.

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