The Lezyne Radar React System represents a breakthrough in cycling safety, integrating radar-based vehicle detection into a premium LED front and rear light set for unmatched protection and visibility. At its core, the system consists of the Radar Drive rear light and the React Drive front light, paired wirelessly through a custom-programmed connection. The Radar Drive continuously scans for approaching vehicles, while the React Drive relays real-time alerts with both visual and audio indicators, giving riders immediate awareness without the need for a phone or third-party device. For enhanced connectivity, the system can also be linked to the Lezyne Radar Ally smartphone app or to compatible GPS cycling computers, delivering radar alerts directly to the rider’s preferred interface. Together, the Radar Drive’s 300 lumens of power with up to 20 hours of runtime and the React Drive’s commanding 1200 lumens with up to 70 hours of runtime ensure full-spectrum visibility day or night, supported by disruptive flash patterns that demand driver attention.

Engineered to thrive in all conditions, the Radar React System features IPX7 waterproof protection and durable CNC-crafted housings, paired with fast and reliable USB-C charging. Its precision optics, advanced LED technology, and seamless wireless pairing create a unified, intuitive safety solution that transforms the riding experience. Cyclists gain not only superior illumination but also the reassurance of a “sixth sense,” with early detection of rear-approaching traffic integrated directly into the lighting system. At just 122g for the Radar Drive and 156g for the React Drive, this system adds minimal weight while delivering maximum peace of mind. With in-house R&D and manufacturing ensuring every detail is refined to the highest standards, Lezyne has redefined what a bike light can be—an intelligent, connected, and indispensable tool for the modern rider. The Radar React System isn’t just lighting; it’s a next-generation visibility platform designed to keep you safer, more aware, and more confident every time you ride.
