Description
Ride with eyes in the back of your head. The Garmin Varia RearVue 820 doesn’t just light up the road behind you, it tells you what’s coming. Built-in radar tracks approaching vehicles up to 175 metres away and feeds real-time alerts to your compatible device, so you know what’s approaching before you hear it.
It’s designed for real-world riding. A bright rear light keeps you visible from up to 2 km away, while the brake light automatically signals when you slow down, helping drivers react sooner. With long battery life and simple mounting, it’s a set-and-forget upgrade that makes every ride feel calmer, safer and more in control, whether you’re commuting, training or heading out on the open road.
