With advanced vehicle tracking, superior battery life, and a brighter tail light than ever before, cyclists can ride with greater peace of mind
Garmin announced the VariaRearVue 820, its most innovative radar tail light that helps cyclists stay more aware and visible while riding. New advanced vehicle tracking detects a vehicle’s size and side-to-side movement and categorizes threat levels as the vehicle approaches from behind, with alerts displayed on compatible Garmin cycling computers or the Varia smartphone app, thanks to more powerful, precise radar technology. This radar tail light is Garmin’s brightest yet and serves as a brake light when slowing or stopping, so riders can feel confident about their visibility to motorists and other cyclists. And with superior battery life of up to 24 hours in day flash mode and up to 30 hours in radar only mode, cyclists can ride even longer with greater awareness and peace of mind.

“We’re excited to expand our trusted cycling radar technology with Varia RearVue 820. Whether cyclists are commuting by bike to work or training along busy streets, this radar can help them stay more conscious of nearby traffic, especially with new, innovative advanced vehicle tracking alerts, all while the brilliant tail light and brake light can help them be more visible.”
–Susan Lyman, Garmin Vice President of Consumer Sales and Marketing
Advanced vehicle tracking
When riding with a compatible Edge® cycling computer or when paired to the Varia™ smartphone app, cyclists will get visual and audible alerts as vehicles are approaching or changing lanes behind them, along with their threat level, which indicates if the approaching vehicle is a higher threat to the cyclist based on its speed or path of travel. And with new vehicle size detection, riders can get visual alerts about the size of approaching vehicles – small, medium, and large – right from their Edge computer or in the Varia app.

More peace of mind
- Boasting a wider field of view, the radar can detect vehicle movement several lanes away and alert riders on their compatible Garmin smartwatch, Edge cycling computer, or the Varia app.
- Powerful radar technology enables the device to detect vehicles up to 190 yards away.
- Using the same speed-tracking, riders are notified when vehicles are following them at the same speed or waiting to pass.
- In addition to vibrating alerts on the 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 smartwatches.

Greater visibility
Ride with greater confidence day and night with Varia RearVue 820’s bright tail light that can be seen over 1.2 miles away and offers multiple light mode options, including day flash, night flash, solid mode, and peloton mode. Cyclists can also create custom light patterns in the Varia app based on their ride’s needs, including brightness level and flash duration. Adding to that superior visibility, the device detects when the rider is slowing down or stopping, then alerts others on the road with a unique, flashing brake light pattern.

Compact design
Featuring a sleek, modern look, Varia RearVue 820 also includes a USB-C port for convenient charging and a new seat post mount that securely and cleanly fits onto almost any road or gravel bike.
Available now, Varia RearVue 820 has a suggested retail price of $299.99. For more information, visit garmin.com.
