It detects vehicles up to 175 meters (more than 190 yards) behind you, tells you how big they are and how they’re moving, and makes sure drivers see you from up to 2 km (1.24 miles) away. For riders who log real miles on shared roads, it’s the closest thing to having eyes in the back of your head.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" aria-level=\"5\"\u003eKey Features\u003c\/h4\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLong-range radar with a wider view.\u003c\/strong\u003e A 60° radar beam tracks approaching vehicles from up to 175 meters away, giving you more reliable alerts and more time to react.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle size and lane-change awareness.\u003c\/strong\u003e See whether an approaching vehicle is small, medium, or large, and when it shifts lanes, with threat levels based on speed, size, and lateral position.*\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAlerts for same-speed traffic.\u003c\/strong\u003e Stay aware of vehicles pacing you, such as a car sitting behind you in slow traffic.*\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eVisible from 2 km away.\u003c\/strong\u003e A 100-lumen day flash and a 220° viewing angle keep you conspicuous in daylight and from the side.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAutomatic brake light.\u003c\/strong\u003e Detects when you slow or stop and switches to a distinct flash pattern to warn drivers and riders behind you.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eUp to 24 hours of battery life\u003c\/strong\u003e in day flash mode, or 30 hours in radar-only mode.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCompact seatpost mount\u003c\/strong\u003e fits cleanly on almost any road or gravel bike.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003e*Requires a compatible Garmin Edge® cycling computer or the Varia™ app.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" aria-level=\"5\"\u003eRadar That Gives You Time to Think\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003eTraffic rarely surprises you once you know it’s there. The RearVue 820 picks up vehicles at more than 190 yards and tracks each one as it closes in, so you can plan your line, hold your position, or ease toward the shoulder well before a car reaches you. Its wider field of view means fewer missed vehicles on bends and multi-lane roads.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" aria-level=\"5\"\u003eSmarter Vehicle Tracking\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003ePaired with a compatible Edge computer or the Varia app, the RearVue 820 does more than signal “car back.” It sorts vehicles by size, shows lateral position and lane changes, and grades each threat by speed, size, and range. A delivery truck closing fast in your lane registers differently than a small car drifting into the next lane over, and you’ll know which is which at a glance.\u003c\/p\u003e\n\u003ch4 dir=\"ltr\" aria-level=\"5\"\u003eAlerts Your Way\u003c\/h4\u003e\n\u003cp dir=\"ltr\"\u003eGet visual and audible alerts on the Varia app or a compatible Edge cycling computer, or feel haptic alerts on a Garmin smartwatch.

The jump in detection range and the vehicle size and lane-change data make it especially useful on fast, open roads and busy commuting routes. If you’re coming in for a fit or a service, our team can help position the mount for clean radar coverage around your saddle bag and seatpost, and pair it with your Edge or watch so it’s ready on your first ride.\u003c\/p\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":53420522340659,"sku":"010-03180-00","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0981\/3685\/0739\/files\/garmin-varia-rearvue-820-bicycle-radar-tail-light-1.jpg?v=1793203261","url":"https:\/\/victorybicyclestudio.com\/products\/garmin-varia-rearvue-820-radar-bicycle-tail-light","provider":"Victory Bicycle Studio","version":"1.0","type":"link"}
