Lezyne Radar React Front+Rear Light Set (With Radar Alerts)

Lezyne Radar React System - LED Front & Rear Bike Light Set With Radar Alerts
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 our 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 our exceptional R&D, in-house manufacturing, and premium features like IPX7 waterproofing and USB-C charging.

Welcome to the future of bicycle visibility: activate your Cycling Sixth Sense.

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