Description

Lezyne upgraded radar-based vehicle detection for cyclists with the Lezyne Radar React System—a solution designed to enhance both bicycle safety and visibility on the road.

This advanced system integrates radar technology into their industry-leading LED front and rear bike light set. Riders can now receive audio and visual alerts through multiple devices: Lezyne Radar Ally smartphone app, compatible GPS bike computers, or directly via the React Drive front bike light.

The Radar Drive pairs with the React Drive to complete the Radar React System. Rear-facing LED indicators and audible alerts are custom-built into the React Drive, providing real-time notifications of rear-approaching vehicles—no smartphone or third-party device required.

This all-in-one system delivers total visibility: radar-based vehicle detection, disruptive daytime flash patterns, and up to 1200 lumens up front for effective night riding. All of this is backed by their exceptional R&D, in-house manufacturing, and premium features like IPX7 waterproofing and USB-C charging.

Note: A smartphone is required for the initial pairing of the system. More information can be found in the Radar React Drive Setup Guide.
