Garmin 010-02376-00 Varia RTL515, Cycling Rearview Radar with Tail Light, Visual and Audible Alerts for Vehicles Up to 153 Yards Away

This device is a gotta-have for riding in light traffic. Has saved my bacon more than once.

The radar/tail light device is really a game changing safety device. The radar almost never fails to warn of approaching vehicles with a very loud warning . It also caused the extremely bright tail light to flash. When I say bright, I mean BRIGHT. All the other tail lights I have seen a wimpy little things that are usually barely visible to approaching vehicles. This one is almost impossible to miss. Overall, I am extremely happy with the device. Like any device you can not count on it 100% to assure your safety but when combined with two rear view mirrors it greatly improves safety. The only problem I encountered was mounting it. The seat post mount was a no go for my bike as I am sure it would be on many others. I had to drill two additional holes offset 45 degrees in the mount piece so I could mount it to a horizontal member of the rear rack. Garmin engineers should have no problem designing a more permanent adapter. The rubber bands that hold it to the rack are not very secure and it tips down on rough terrain/country roads. Despite this problem, I would award more stars if they were available. Two hundred bucks may seem expensive but compared to hospital/burial costs, it is nothing.

Nice safety light never go out with out it.

This connected to my Wahoo Element with no issues. Great to know when there is traffic behind you and when it is clear.

A super device which came relatively quickly

Let me start off by saying, Ive been biking since my 20s, now in my 50s. Im what I consider a long distance, casual, organize touring biker. In other words Im not a racer. Im not sure how this device has escaped me for as long as it has. I used this radar for the first time on a 20 mile loop only due to the time of day. I must say I was very excited with the way the radar performed. For the first 5 to10 mins I still looked over my shoulder. Once I had a handle on where the car or cars were in relationship to what I saw on my phone. I felt pretty confident with using the radar. Sometimes when you have to rely on your hearing or looking over your shoulder some quieter vehicles manage to sneak up on you especially if the wind is blowing in the opposite direction that you are riding. You then have to make a split second decision on whether to avoid bad road pavement and possibly creating a close call situation or play it safe with the car and pray you and your bike survives hitting a pot hole, gravel, etc. I feel with the radar it allows you to focus more on the road ahead of you, instead of constantly looking over your shoulder. Which actually allows you to make a more informed decision on navigating the pavement, because you see ahead of time where the cars are in relationship to you. Im very satisfied with that feature. I use the radar with the Varia app on my retired LG G7 phone. They both work well together. Im very happy with the app. Its a very basic, lean, and clean app. Its not loaded with a bunch of unnecessary options. It does just what it is suppose to. I may be a little picky, but I just wish that I had the ability to turn off the light and continue to keep it linked to the app. I probably would not use it that way, but it would be nice as option if you need to stretch the battery life a little longer. Definitely not a game changer. Also the bracket is okay, not a big fan of the silicone like stretchy bands for attaching expensive devices on the back of my bike that could possibly brake loose and I may not know in time if the device fell off my bike. I also wish that garmin would make a bracket that allows the radar to be extended pass your saddle bag. I since have ordered a K- Edge Go Big Pro Saddle Rail Go Pro Camera Mount. I was also going to order a 3d garmin to Go Pro adapter to attach to the mount, but i decided to buy a For Garmin Varia Radar RTL510 tail light mount holder saddle bracket off Ebay. This bracket is much shorter, but I only bought it to remove the garmin attachment and attach that to K-Edge. The housing around the garmin attachment is made of medal, which I feel would be better than a plastic 3d adapter. Hopefully with the extra length that the K-Edge has it will be just long enough to clear my saddle bag. I will update when I acquire all of the above mentioned mounts. Oh by the way there are similar mounts on here on Amazon like the RTL510 that also include the garmin attachment, but it seems like they all ship from China. Which would be okay if your willing to wait 5 to 7 weeks.

It’s like having eyes at the back of your head. Works really well with Ride with GPS on my phone.

Very easy to setup on my bike, and to the Varia app on my phone. Having this device added a level of comfort by alerting me to approaching vehicles well in advance. I was able to track progress and gap closure very easily.

100% happy with this purchase

Very helpful in warning the rider about to be passed by a vehicle, especially on narrow mountain roads where I ride in Alpine County CA. The warning souind could be a bit louder during windy conditions but I believe that is a funtion of my cell phone. I definitely feel safer riding solo and I hardly feel the need to keep checking my mirror.
