It’s like having eyes on the back of you head with the Varia Rearview Radar by Garmin! Lauded as the world’s first cycling radar, this newly released system includes a radar tail light transmitter and a radar display unit for your handlebars. The radar tail light detects vehicles approaching from up to 153 yards behind you. On the display unit, you’ll see up to 8 vehicles at a time noted as blips on your screen, with the color changing as they come closer. The tail light also brightens and flashes as cars get closer. Make your ride safer with Varia.
