It’s a simple, effective solution for cyclists of all abilities to enjoy added safety and visibility, no matter their style of riding. The light’s disruptive daytime flashing and powerful night-riding lumen outputs are exceptional for total visibility, day or night.

The React Drive provides up to 1200 lumens, making it exceptional for both daytime visibility and nighttime illumination. It features a first-of-its-kind built-in vehicle alert system: when paired with the Radar Drive rear bike light, rear-facing LEDs activate and audio cues are triggered when vehicles are detected. No GPS bike computer or smartphone app is required, offering a simple, self-contained safety improvement. This is bicycle safety redefined through intelligent R&D. A robust strap mount enables fast, secure attachment across a range of handlebars. The unit is housed in a lightweight, durable, CNC-machined aluminum body.

Radar Drive Rear The Lezyne Radar Drive is a high-performance rear bike light designed to enhance rider safety and visibility through advanced radar-based vehicle detection and powerful LED output. Its custom-tuned radar system detects rear-approaching vehicles in real time from up to 150 meters away. The light can operate independently as a taillight featuring its own unique flash pattern that’s triggered when a vehicle is detected.

This system can operate independently of a phone app or bike computer, providing audio and visual alerts through the React Drive’s built-in features. Alternatively, when paired with compatible GPS bike computers or the Lezyne Radar Ally smartphone app, it delivers real-time audio and visual alerts.
