Lezyne has redefined radar-based vehicle detection for cyclists with the Lezyne Radar React StVZO System—a solution designed to enhance both bicycle safety and visibility on the road. 

This advanced system integrates radar technology into our industry-leading LED front and rear StVZO bike light set. Riders can now receive audio and visual alerts through multiple devices: 

  • Lezyne Radar Ally smartphone app,
  • Compatible GPS bike computers, or
  • Directly via the React StVZO Front bike light. 

The Radar StVZO Rear pairs with the React StVZO Front to complete the Radar React StVZO System. Rear-facing LED indicators and audible alerts are custom-built into the React StVZO Front, providing real-time notifications of rear-approaching vehicles—no smartphone or third-party device required.

This all-in-one system delivers TOTAL VISIBILITY: radar-based vehicle detection, additional daytime visibility, and up to 600 lumens up front for effective night riding capabilities.

The system was developed though exceptional R&D and in-house manufacturing, and offers premium features like IPX7 waterproofing and USB-C charging.

Welcome to the future of bicycle visibility: activate your Cycling Sixth Sense.

Note: A smartphone is required for the initial pairing of the system. More information can be found in the Radar StVZO Drive Setup Guide.

sleeves long
I'm 5'6" and stocky but the sleeves are too long and slip over to rest half way down my hand. If your 5'9 or taller you will be fine.
