Lezyne Radar React – the sixth sense for cycling. This smart lighting system combines a bright rear light with state-of-the-art radar technology. Like an invisible rearview mirror, it detects vehicles from up to 150 meters away and warns you visually and/or audibly, either through the Lezyne Radar app on your smartphone or via your bike computer. Thanks to the dual radio system (Bluetooth & ANT+), you can easily pair the system with the Lezyne Radar app, numerous ANT+ head units, or the React Drive front light. The installation is simple and tool-free: the handlebar mount and various rear light adapters fit all common handlebars and seat posts (aero profiles are included). Complete system "Radar React System": The connected light duo of the Radar Drive rear light and React Drive front light significantly increases your visibility: the rear light detects approaching vehicles and transmits warnings directly to the cockpit. There, integrated LED signals alert you to the approach. Both lights can be manually controlled via the app, are IPX7 waterproof, and charge via USB-C. Performance that impresses: up to 1,200 lumens in the front (six modes, up to 70 hours in daytime running mode) and 300 lumens in the rear (seven modes, up to 20 hours in flashing mode). With versatile straps, everything sits securely – on handlebars, round, D-shape, or aero posts.
