The Varia™ RTL515 rearview radar provides visual and audible alerts for vehicles approaching from behind up to 140 meters away.

This radar works perfectly with the Edge cycling computer or with a compatible smartphone and some Garmin wearables, or even with the optional radar display.

This smartphone app helps you improve awareness of your surroundings by providing images, as well as audible and vibration alerts, indicating the position and speed of approaching vehicles.

When used with a compatible smartphone, the radar integrates with your favorite apps, such as Ride with GPS, to overlay rear radar alerts on maps.

Alert motorists to your presence as early as possible with daytime visibility up to over 1.5 km.

Easily mount this compact and sleek device on the saddle of almost any road bike. The vertical design leaves more space for your legs and allows you to pedal without obstruction.

Varia™ RTL515 includes multiple modes, including Group mode, which emits a low-intensity flash that does not disturb the vision of other cyclists in the group.

Time spent charging is not as important as time spent riding your bike. Up to 16 hours of battery life in daytime flash mode and up to 6 hours in steady mode.
