Garmin Varia RearVue 820 combines advanced radar detection with a high-visibility tail light to enhance cycling safety. The radar identifies approaching vehicles and threat levels across an expanded field of view, alerting you via compatible Edge computers, Garmin smartwatches, or the Varia app. A distinctive brake-flash pattern signals deceleration to road users behind you. The tail light projects visibility up to 2 km, while extended battery performance delivers up to 24 hours in day flash mode or 30 hours in radar-only mode, supporting extended rides without frequent charging.

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® cycling 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.
