Ride safer, stay seen, and stay aware — without needing a Garmin.

Bright lights help drivers see you. Radar helps you see what’s coming.

By detecting vehicles approaching from behind and triggering intelligent alert patterns, the Lezyne Radar Drive adds a proactive layer of safety — especially valuable on open roads, fast descents, and high-traffic routes.

The Lezyne Radar Drive Rear Light combines a powerful 300-lumen LED taillight with advanced radar technology that detects vehicles approaching from up to 150 meters away. Designed for cyclists who want Varia-level performance at a more accessible price, this all-in-one safety system delivers real-time awareness and unmatched visibility on every ride.

The custom-tuned radar tracks rear-approaching vehicles and can trigger an automatic alert flash pattern, instantly increasing visibility when it matters most. Use the Radar Drive on its own, pair it with compatible GPS bike computers (Bluetooth or ANT+), or connect it to the Lezyne Radar Ally app for audio and visual notifications.

For even deeper integration, it pairs with the React Drive front light, creating Lezyne’s first-of-its-kind Radar React System — an independent alerting setup that doesn’t require a phone or cycling computer.

Built for real-world riding, the Radar Drive offers:

• Up to 20 hours of runtime
• Durable co-molded construction
• IPX7 waterproofing
• Wide 270° visibility thanks to Lezyne’s engineered optics
• Secure mounting to round, aero, and D-shaped seatposts

Perfect for road cyclists, gravel riders, commuters, and triathletes who want real-world safety and visibility, without compromise.
