Radar React - the sixth sense for cycling. The smart light system combines a bright rear light with state-of-the-art radar technology. Like an invisible rear-view mirror, it recognises vehicles from up to 150 m away and warns you visually and/or acoustically, either via 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 easy and requires no tools: 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 visibility in traffic. The short-term warning signal (Alert Flash) is automatically activated when a vehicle approaches. Seven light modes including daytime running light provide up to 300 lumens with up to 20 hours of runtime. 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 fastening straps ensure secure mounting; D-shape and aero adapters are included in the scope of delivery.
