See and be seen with Garmin’s most powerful and precise rearview radar yet. The Varia RearVue 820 combines advanced vehicle detection with an ultra-bright tail light to help you ride with greater awareness and confidence.

 

Powerful Rear Radar Detection

The integrated radar tracks vehicles approaching from up to 175 meters (190+ yards) away with a wider field of view than ever before. When paired with compatible Edge® cycling computers, Garmin smartwatches, or the Varia™ smartphone app, you’ll receive visual, audible, and even haptic alerts so you can stay focused on the road ahead.

 

Exceptionally Bright Visibility

The tail light is visible from up to 2 km (1.24 miles) away, helping drivers see you sooner. A built-in brake light automatically detects when you’re slowing or stopping and flashes a unique pattern to alert traffic behind you.

 

Advanced Vehicle Awareness

See the size of approaching vehicles, get lane-change alerts, and monitor threat levels directly on compatible devices. The system even helps you stay aware of vehicles traveling at the same speed.

 

Customizable Light Modes

Choose from day flash, night flash, solid mode, or peloton mode, which reduces glare for riders behind you. You can also customize light patterns using the Varia app.

 

Long Battery Life & Compact Fit

Get up to 24 hours of battery life in day flash mode. The sleek, compact design and updated seatpost mount fit cleanly on most road and gravel bikes. Compatible with the Varia seat rail mount kit (sold separately).

Strikingly visible. Remarkably powerful. The Varia RearVue 820 gives you an extra layer of awareness every time you ride.
