Lezyne Radar React – the sixth sense for cycling. This smart lighting system combines a bright rear light with cutting-edge 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 wireless system (Bluetooth and ANT+), you can easily pair the system with the Lezyne Radar app, numerous ANT+ head units, or the React Drive front light. Installation is simple and tool-free: the handlebar mount and various rear light adapters fit all standard handlebars and seat posts (aero profiles are included). The Radar Drive rear light combines a bright rear light with radar technology for maximum awareness in traffic. When a vehicle approaches, the short-term warning signal (Alert Flash) is automatically activated. Seven lighting modes, including daytime running light, provide up to 300 lumens with a runtime of up to 20 hours. The wide-angle optics offer 270° visibility, and the robust composite construction is IPX7 waterproof. The Radar Drive rear light is conveniently charged via USB-C. Versatile mounting straps ensure secure installation; D-shape and aero adapters are included.
