This Sensor Has Your Back

When out on a ride, you have to keep track of everything. What’s your route, how far are you going, how fast and how hard are you going to push it. But with Varia radar along for the ride, it’s like having eyes in the back of your helmet. It’s essentially an early warning system so you see cars approaching from behind, and they see you.

Safety in Numbers

Varia RTL510 rearview radar is just one part of cycling awareness. When paired with compatible Garmin devices, the system helps to create safer riding environment by alerting riders to vehicles approaching from behind. Green light? All good. Amber light? A vehicle is approaching. Red light? Take caution — a vehicle is approaching at high speeds. Ride safe.
