Lezyne Connect Smart / Ktv Smart

Once you pair the lights using the Lezyne LED Ally app, the front light acts as a master controller. When you cycle through your programmed light modes on the front unit, the rear light automatically switches to match, so you don't have to reach back to adjust settings while riding.

Yes, the LED Ally app allows you to create custom mode sets. You can select only the modes you actually use, which makes toggling through them much faster during your ride.

The lights use a versatile strap mounting system designed to stretch around various bar shapes, including aero and oversized handlebars. It is a secure, tool-free setup that works on most standard bike frames and seatposts.

The rear light features an IPX7 waterproof rating, meaning it is fully protected against heavy rain, splashes, and even temporary submersion. You can ride with confidence in almost any weather condition.

The front light offers up to 87 hours of runtime, while the rear provides up to 19.5 hours, though these maximums are achieved on the lowest output settings. For high-intensity riding, expect significantly shorter runtimes, so it is best to recharge after long or frequent rides.

The front light is built with an aluminum body designed to dissipate heat effectively. While it may feel warm to the touch during operation, this is a normal part of the cooling process that helps protect the internal electronics.
