The Lezyne Radar React System is an advanced front and rear lighting package designed to improve rider safety through integrated radar technology and high-output LED illumination. Combining the powerful React Drive Front Light with the Radar Drive Rear Light, this intelligent system detects approaching vehicles from behind and provides real-time visual and audible alerts, helping riders stay aware of traffic without taking their eyes off the road. Compatible with GPS bike computers and the Lezyne Radar Ally App, the Radar React System delivers an extra layer of confidence for road cyclists, commuters, and e-bike riders alike.

The React Drive Front Light produces up to 1200 lumens of powerful illumination for night riding and daytime visibility, while the Radar Drive Rear Light offers up to 300 lumens and uses radar technology to detect vehicles approaching from up to 150 metres away. The front light's integrated alert panel provides clear visual warnings and audible notifications, allowing riders to receive radar alerts even without a cycling computer. Both units feature USB-C charging, IPX7 waterproof construction, and long battery life for dependable performance in all weather conditions.

Whether you're training on open roads, commuting through traffic, or exploring new routes, the Lezyne Radar React System helps you see more, be seen more, and ride with greater confidence.
