Garmin Varia Rearview Bike Radar
As long as roads are shared, biking will to some degree be inherently dangerous. Make it less so with the Garmin Varia Rearview Bike Radar. Consisting of a radar-equipped taillight and a stem-mountable head unit — both wirelessly linked — Varia detects vehicles approaching from behind at distances up to 153 yards and warns of their individual relative speeds and threat levels so you can react appropriately. It also brightens and flashes the taillight to grab the attention of approaching drivers and integrates with Garmin’s Edge cycling computers for seamless warnings alongside cycling information and turn-by-turn directions.
