Lezyne KTV Smart Front and KTV Pro Smart Rear Light

The front light acts as a master controller. Once you pair both lights via the Lezyne companion app, you can toggle modes on the rear light directly from the front unit or your smartphone, eliminating the need to reach back to adjust settings while riding.

No, both units feature integrated USB sticks. You simply remove the light from the mount and plug the built-in connector directly into any USB port, making it a cable-free and convenient process.

The 200-lumen front light is excellent for urban commuting and being seen by traffic, but it is not intended for high-speed mountain biking or pitch-black trails where you need to see far ahead. It is best suited for city streets, bike paths, and general visibility.

Yes, both lights are built with an IPX7 waterproof rating. This means they are fully protected against heavy rain, splashes, and even temporary submersion, so you can ride confidently in wet weather.

They use a versatile clip-and-strap system designed to fit a wide variety of handlebar and seat post shapes. The setup is secure and keeps the lights stable even on bumpy roads.

The battery life varies depending on the mode you choose, but you can expect up to 20 hours of runtime on the most efficient settings. For high-output modes, the runtime will be shorter.
