Varia RearVue 820 Cycling Radar with Tail Light
Loading store availability...
Varia™ RearVue 820 is the rearview radar and tail light that alerts you to approaching vehicles on your compatible Edge® cycling computer, Garmin smartwatch or Varia™ app on your smartphone. With our most powerful and precise radar tracking technology, it detects vehicle size and threat level with a wider field of view. The radar tracking technology identifies vehicles that are following cyclists at the same speed1 or attempting to pass. The tail light is visible from up to 2 km (1.24 miles) away and has a unique brake light flash pattern to alert other road users when you’re slowing down or stopping. For peace of mind and awareness on the longest of rides, get up to 24 hours of battery life in day flash mode and up to 30 hours of battery life in radar-only mode.

A must for anyone doing road cycling. It’s made my ride a lot safer as it’ll warn you of incoming kook cyclists too.
Excellent product that provides massive peace of mind on busy roads. The integration is seamless with my Garmin head unit; it picked up the sensor immediately and the alerts are clear without being too distracting. Highly recommend for any road cyclist.

Tool was exactly how described and packaging was nice. It did take a few days to ship so unfortunately I didn’t receive it in time for the trip I ordered it for which is the reason for 3 stars but I received it the week after and it’s coming in handy.
size is big enough and clear simple layout. moved from garmin 850. I am very satisfied with wahoo!
Sierra is no joke, this is our 4th bike in the last 3 months and the process has been so easy, they are fair with pricing and never make it feel transactional! I won't be buying anywhere else!
