POWERFUL AND RELIABLE RADAR
With our most powerful and precise radar tracking technology, Varia RearVue 820 bike radar detects vehicles approaching from up to 175 metres away with a wider field of view.

BRIGHT TAIL LIGHT AND BRAKE LIGHT
Our brightest tail light means you’ll be visible from up to 2 km (1.24 miles) away. A brake light detects when you’re slowing or stopping and displays a unique flash pattern.

ADVANCED VEHICLE TRACKING
See alerts for small, medium and large vehicles, and see when a vehicle changes lanes, along with its threat level — when riding with the latest compatible Edge® bike computers or the Varia™ app on your smartphone.

GET ALERTS YOUR WAY
For visual and audible alerts while you ride, connect this bike radar to the Varia smartphone app, compatible Edge bike computers or Garmin smartwatches. In addition to haptic alerts on your wrist, selected Garmin smartwatches can also give voice alerts for approaching vehicles — this feature is currently available in the Garmin Public Beta programme for selected smartwatches³.

VARIETY OF LIGHT PATTERN OPTIONS
Ride with four different light patterns: day flash, night flash, solid mode and peloton mode, which helps preserve the eyes of riders behind you. Create your own custom light patterns in the Varia app on your smartphone.

COMPACT DESIGN
A sleek, compact design and new seatpost mount means Varia RearVue 820 fits cleanly onto almost any road or gravel bike and is compatible with the Varia seat rail mount kit (sold separately).

1 - When riding with your compatible Edge® cycling computer or the Varia™ app on your smartphone.
2 - Same-speed tracking is limited or may be unavailable at slower speeds or when radar cannot detect the road (e.g., due to snow, ice, heavy rain, or other obstructions or incorrect device mounting).
3 - This feature is currently in public beta testing and subject to future enhancements.
