Lezyne KTV PRO+ Ai Alert rear light black

Description

In the city and on country roads, a good rear light comes down to one thing: others know you’re there in time. The Lezyne KTV PRO+ Ai Alert rear light black gives a clear signal when you slow down and adds confidence in situations where traffic changes from one second to the next. It’s a small detail on the bike, but one that can make a big difference in how safe you feel.

Main benefits

Lezyne KTV PRO+ Ai Alert is a rear bicycle light with smart Ai Alert technology that intelligently detects deceleration and switches to a bold “brake” signal, so drivers and other cyclists immediately understand what’s happening. Thanks to Wide Angle Optics, the light is visible across a wide 270° angle, so you’re not just “a dot” from directly behind—you remain easy to read from the sides as well. You’ll also appreciate multiple lighting modes, including daytime flash, which helps you stay noticeable even in bright daylight. And importantly, Ai Alert is pre-set and does not collect rider data.

Technical specifications

Maximum light output is up to 150 lumens, which is practical for prominent flashing in heavier traffic as well as for daytime use. In the Femto power-saving mode, it offers up to 20 hours of runtime, so you don’t have to worry about charging after every ride. Power comes from a rechargeable 400 mAh battery, and charging is handled via an integrated USB stick, meaning no extra cables. The single LED design is durable, and the light is tested to IPX7 water resistance; with a body size of 60 × 41 × 64 mm, it weighs just 50 g, and mounting is secured by a silicone rubber strap compatible with both round and aero seatposts.

Conclusion

If you’re looking for a rear bike light that’s highly visible, can handle rain, and clearly communicates braking, this model makes sense. KTV PRO+ Ai Alert is suitable for everyday commuting as well as fast-paced training rides where simple operation and reliable visibility matter.
