The intuitive, custom-programmed Lezyne Radar Ally app is the centerpiece of our innovative Radar React System.

You can also use the Radar Ally app to pair the React Drive front light with the Radar Drive taillight. Once paired, the React Drive features built-in visual and audio vehicle detection alerts, allowing you to ride phone-free without compromising awareness on the road. 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.
Compatible Lights:
React Drive 1200 This powerful LED front bike light integrates advanced technology with precision-engineered design to significantly enhance rider safety and visibility. 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. It’s IPX7 waterproof-rated and USB-C rechargeable, with up to 70 hours of runtime.
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.
The Radar Drive can seamlessly pair with the Lezyne React Drive front bike light to create an innovative system. 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.
The light offers seven output modes, including a highly disruptive 300-lumen daytime flash. Its co-molded construction is durable, waterproof (IPX7), compact, and boasts its own unique styling. Additional features include a USB-C charging port, up to 20 hours of battery runtime, and a versatile strap-mount system compatible with round, aero, and D-shaped seatposts.
