Lezyne Radar React System Overview

The Lezyne Radar React System is designed for cyclists who want greater awareness, confidence and visibility every time they head out on the road. By combining powerful LED lighting with radar based vehicle detection, this innovative setup acts like a cycling sixth sense, alerting you to approaching traffic from behind while keeping you highly visible in all conditions.

This advanced system pairs the Radar Drive rear light with the React Drive front light, creating a fully integrated solution that works straight out of the box. Riders receive visual and audio alerts directly through the React Drive, with no need to rely on a phone or third party device while riding. For added flexibility, the system can also connect to the Lezyne Radar Ally smartphone app and compatible GPS bike computers.

With up to 1200 lumens at the front and 300 lumens at the rear, the Lezyne Radar React System delivers excellent performance for both daytime visibility and night riding, making it a strong choice for British roads and changing weather conditions.

If you ride on busy roads, commute regularly or enjoy long weekend miles, knowing what is happening behind you is a huge advantage. The Lezyne Radar React System detects rear approaching vehicles in real time and alerts you instantly, helping reduce surprises and giving you more time to react. Combined with disruptive daytime flash patterns and powerful LEDs, it significantly improves rider safety and confidence.

Who Is It For?

This system is ideal for road cyclists, commuters and endurance riders who want an all in one visibility and safety upgrade. It suits riders who prefer a clean setup without constantly checking a phone, while still offering app and GPS connectivity for those who want deeper integration.
