Product details
Reliable visibility. Comprehensive overview - with the Varia RearVue 820 bike radar with very bright rear light.
The radar warns you of approaching vehicles on compatible Edge® bike computers, Garmin smartwatches or in the Varia app on your smartphone. The Varia RearVue 820 uses innovative radar technology to recognise the size of the vehicle and visually shows you the overtaking distance. Regardless of whether you are travelling at the same speed or overtaking - vehicles are detected from a distance of up to 175 metres. The very bright rear light with various light modes is visible from distances of up to 2 kilometres and has an integrated brake light with a striking flashing pattern. This warns other road users when you slow down or stop.
