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. 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). The React Drive front light delivers up to 1,200 lumens. It features a housing made of CNC-machined aluminum, a robust design, and an optimized lens/optics for broad, clear illumination. In conjunction with the Radar Drive, the front light displays LED warning signals as vehicles approach from behind – keeping you informed at all times. Six modes, including daytime running light, provide illumination for up to 70 hours. The Infinite Light Power Pack+ can extend the runtime if desired. The app offers enhanced control options. IPX7 waterproofing, USB-C, and a versatile mounting strap complete the package.
