Product Overview
The Garmin Varia RTL515 Cycling Rearview Radar is a must have for any serious cyclist. This revolutionary device provides cyclists with the ability to be aware of vehicles approaching from behind up to 153 yards 140 meters away. This makes it an essential piece of safety equipment for those who ride in busy urban areas, or on roads with a lot of traffic.
The Varia RTL515 pairs seamlessly with your Edge bike computer and compatible smartphone, as well as select Garmin wearables or the radar display unit. When used with a compatible smartphone, the Varia app allows you to receive graphics plus tone and vibration alerts that indicate approaching cars. The Varia radar also integrates with third party apps such as Ride with GPS, which can overlay your maps with rearview radar alerts.
This device is incredibly easy to install and use. It comes with a mounting kit, cables and documentation that make installation straightforward and simple. The vertical design mounts easily to most road use bicycles, and the battery life is impressive up to 16 hours in day flash mode, up to 6 hours in solid mode so you can go for longer rides without worrying about having to recharge it. It also has a Peloton mode which provides a low intensity light flash that is perfect for cycling in groups or when you want extra visibility on the road.

The brightness of the Varia RTL515 is also noteworthy it has visibility up to one mile which gives motorists plenty of warning that you are on the road ahead of them. This makes it an excellent choice for cyclists that ride at night or in low light conditions since it will help keep you safe while also making sure other drivers are aware of your presence on the road.
Overall, I highly recommend the Garmin Varia RTL515 Cycling Rearview Radar for anyone who rides regularly on roads with lots of traffic or at night. It provides an extra layer of safety by allowing you to be aware of vehicles approaching from behind, and its combination of visibility and battery life make it an ideal choice for any cyclist looking for peace of mind while they ride.
