For visual and audible alerts while you ride, connect this radar to the Varia smartphone app, compatible Edge cycling computers or Garmin smartwatches. In addition to haptic alerts on your wrist, select Garmin smartwatches can also give voice alerts for approaching vehicles — this feature is currently available in the Garmin Public Beta program for select smartwatches3.
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.
A sleek, compact design and new seatpost mount means Varia RearVue 820 fits cleanly onto almost any road or gravel bicycle and is compatible with the Varia seat rail mount kit (sold separately).
