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.
