With its Varia RearVue 820, Garmin promises to continue revolutionising cycling safety by combining a powerful rear-facing radar with a high-performance red light. This next-generation model, which succeeds the classic Varia, detects vehicles up to 175 metres away with an expanded field of view. It identifies their size—whether a motorbike, car or lorry—and assesses their level of threat in real time. This radar offers advanced vehicle tracking by displaying lane changes. Alerts are clearly displayed on your Garmin bike computer or via the app, allowing you to keep your eyes on the road. These alerts can be visual and/or audible.

With a claimed visibility of up to 2 kilometres, this rear light reaches 100 lumens in Day Flash mode. It offers several lighting modes (steady, peloton, day/night flash, custom mode) and features an automatic brake light function that brightens when you brake. Waterproof to IPX7 standard, with a battery life of up to 24 hours and weighing just 90 grams, it will quickly become indispensable for all your cycling trips. With its sleek and compact design, this rear light installs quickly using a new seatpost mount compatible with the vast majority of bikes.

Thanks to all these features, the Garmin Varia RearVue 820 is simply perfect for cyclists who want maximum peace of mind, visibility and safety on the road amongst other road users.
