Description
Radar Tail Light with up to 2km of visibility
The new Varia RearVue 820 Radar Rear Light features the advanced technology riders have come to expect from Garmin. Designed for road cyclists, it adds a new level of awareness and safety to every ride.
Features
- Tracks vehicles up to 175 metres away with wider field of view
- Up to 24 hours of battery life (in day flash mode)
- Bright tail light is visible up to 2km away
- Brake light alerts others that you’re slowing or stopping, displaying a unique flash pattern
- 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.
- 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 smartwatches.
- 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 bike and is compatible with the Varia seat rail mount kit (sold separately).
