Connect to our custom Radar Ally phone app, compatible GPS head units, or pair it with our React Drive Front light for visual and/or audio alerts. Activate your cycling sixth sense with the Radar React System.

React Drive 1200
With the React Drive Front light, a simple, innovative solution for receiving vehicle detection alerts has been revealed. When connected to the Radar Drive Rear taillight, rear-facing LED indicators on the React Drive Front will illuminate when a vehicle is detected from behind. This clever feature brings an alternative to the need for a cycling computer or a phone app to receive alerts. Just you, your lights, your bike and your peace of mind.

Radar Drive Rear
The new benchmark for radar activated bike taillights.
The Radar Drive Rear is a wonderfully sleek and powerful cycling taillight. It features a robust construction, IPX7 waterproof rating and undeniable style. Boasting a 250-lumen day flash mode and a 300-lumen active alert feature, the Radar Drive Rear demands attention. Its radar detection starts tracking vehicles from 150 meters out, and sends alerts to compatible head units in addition to the Lezyne Radar Ally app and/or React Drive Front bike light. Mounting is quick and versatile, easily strapping to a variety of seatpost styles. It features up to 18 hours of runtime and is rechargeable via USB-C.
