Description

A New Set of Eyes In the Back of Your Head

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.

A Great New Radar Tail Light

My old Garmin Varia was only holding a charge for around 3 hours. So, it was time to replace it. This tail light was just released. I've been happy with other Lezyne products and this was also about $50 less than the base Varia model and way less than the new Varia. I've now used it for about 2 weeks and I'm really happy with the performance of this product. The warnings are exactly the same as the old Varia. I've not had any false positives or false negatives. On top of all that, I got 14 hours of riding out of my first charge. That's about double what I ever got out of the Varia, even when it as new.

The only downside to this light is the way it attaches to your bike. It's just a rubber strap around your seat post. There's no way to attach it to a tab on a saddle bag or saddle rails. It's easy to move from bike to bike, but I wish there was more flexibility in where you can mount it.

Even with the lack of mounting options, I'm still very happy with this tail light.
