Review by Gene Kriegsmann
The vast majority of the 150 Miles per Week that I ride are on roads. The Varia Radar in conjunction with my Edge 1030 Plus make those rides far safer. The unit starts to flash as soon as it "sees" an approaching vehicle. I was told by a UPS driver that he could see the flash as far back as 3/4 of a mile in bright sunlight. That anyone who claimed they didn't see it was either blind or lying. Simultaneous with the intensified flash a display on the computer screen tracks the approaching vehicle. I have found it is quite easy to estimate the relative speed of the vehicle. As many as 6 individual cars have shown simultaneously in the display. The display is tinted red until the last vehicle has passed, then it turns green indicating the road is clear. No car has ever passed me and not shown on the display well in advance. It is absolutely essential when I have to move across the lane to reach a left turn lane. This unit is my second one. The earlier one was still going strong after more than three years of use, and many thousands of miles of travel. I mistakenly thought that the battery was weakening, and chose to replace it. That is fine. I gave it to a friend who will continue to use it, likely for many years to come. Of all the safety gear I have purchased over the years, this is the best. For those who might wonder, it is also usable with Wahoo computers.

This radar simply works. using it for months now and only 1 time it missed a car that followed another one. It gave me the confidence to know vehicle is coming up behind me and not get scared by someone suddenly fly by next to me. the light is also nice and bright.

A lot of bike tech these days seems like overkill but that's not the case with this. It has made my commute safer and I wouldn't feel as comfortable riding without it. I use the Garmin 530 and the ap on my phone. I keep one earbud in while riding to get the sound alerts. I love the color sequence that it goes through: orange means a slower vehicle, red means a faster vehicle and green means all clear. After using since last May to commute, I can honestly say I have yet to see a false positive or negative. The only issue I had was my old pannier system blocked the sensor. so I had to swap that out. Otherwise, this thing works flawlessly and makes my daily commute safer. I hated the small mirror I used to use on my bar end which was way to distracting.

There are some roads that I ride that require me to constantly turn and look for cars approaching from behind. With this new radar those days are over. I now know when a car is approaching so I can get over on the shoulder. Love it.

The Garmin Varia is a great device for informing you of any traffic (car or otherwise) overtaking you from behind. This device alarms (if you want) and has a visual proximity indicator, giving you ample time to shelter as close as possible to the side of the road.
I found the device to be most helpful not on busy roads while commuting, but on longer rides at those moments when riding two-abreast, it's a great reminder to fall into single file, as it alarms or notifies you with plenty of time to make this adjustment.
Hard to ride without it at this point!
Review by Peggo
This is a great device for making me aware of vehicles behind me. I used the Varia app on my smartphone and strapped the phone to the bar. I was constantly amazed by how far away the radar sensed vehicles behind me. Both the graphic and audible alert on the phone are great! However, I do not like the large phone on the bars so have purchased a Garmin Edge 830 to use instead and hope the alerts on the Edge will help as much as the phone app did ! I was more relaxed riding having this one more tool in the box (besides listening, looking behind me and using a mirror). The radar picked up vehicles often before I could see any detail in my mirror or hear it so it helped me stay alert and avoided those last minute surprises that can happen when a fast vehicle suddenly shoots around you.
Review by HerbP
Another on-line review said there are two kinds of people: those who don't have a Varia and don't see the need for one and those who have one and wouldn't ride without it. I moved from the first group to the second.
Easy interface with Wahoo computer. I turned off the audible alerts: TMI and annoying. But glancing down from time to time I see what's coming well before I hear it. I've tried to catch it making errors but so far have not been able to. Even tells you how many cars are coming. The LED alerts are usually washed out in daylight so are not that helpful.
Review by Dave O
I have my Varia RTL515 mounted on the back of my seat bag so the radar unit is positioned high for maximum distance and no interference from the rear tire. Although I like using it on small group rides it seems to be most beneficial on solo rides, keeping me aware of all rear approaching vehicles in plenty of time. The unit works as advertised and is living up to my expectations although I would have liked longer battery life. Isn't that always the case.
Review by Walt
I really like that the Varia, coupled with my Garmin cycling computer, let's me know what is happening behind me without needing to look behind and check or rely on what I hear. I also like the I brightness, visibility and long battery life associate with using the "day flash" mode on the light! I feel safer on rides using this Varia RTL515 device!
Review by aerodienamic
It might be an illusion of safety, or just something to make you more aware of what is happening behind you. I for one have been hit by a car, and this little device has made me feel more confident with being out on the road alone. I would recommend this to anyone who ride a lot outdoors. I would say that riding in an area with higher density of population (ie City with a lot of cars) its starts to lose it value, I found that its better out on an open road in a suburban or rural area.
Review by FCoons
I used to rely on handlebar mirrors and/or quick glances over my shoulder to check for cars behind me, but the Garmin Varia has been a savior and at least replaced the mirrors. The read out display on my Garmin head unit gives and audible warning and also provides ample alert to cars approaching from the rear. If there is any concern it is that while in group rides with teammates behind me the radar can sometimes confuse cars and bikes and filter out the warning, but perhaps I don't have the unit set correctly to accommodate for both bikes and cars behind me. I will not ride again without the Varia on my bike and should have purchased it when it first came out.

I use this light while riding solo and group riding in my area. I feel safer with the notifications although it picks up other cyclists riding behind as well. I don't like that it takes up a lot of real estate on my seatpost so that I can't use a saddlebag. I like everything else about it.
Review by HO
This is, without a doubt, one ofnthe best purchases I have made. I ride in a city where most streets don't have bike lanes, so it used to be a constant craning of the neck to check on traffic. The radar on this light is amazing. It is highly accurate and gives a city block distance of warning of approaching cars. I never look back now. I ride how I want, and pull to the shoulder when the radar beeps. An incredible experience. Only issue is with integration with my Edge 820 (it won't connect unless another sensor first connects, Garmin is no Apple) but once it does, it is perfect.

A friend recommended this to me and I bought one. I love it. For a techie product, I love that it just works. Easy peasy. It is a substantial safety improvement to see cars approaching from behind. It is really the only game changer in many years. I bought an Edge 130 computer to go with it, replacing an older computer, and it is great, too. The best thing is that 1) I can work it, and 2) it requires no sensors. No wires, no batteries to keep replacing. I liked it so well I bought my daughter the same kit.
Review by rewinans
this model works quite well with my 1030 edge computer, a previous version did not work. Does not have a real long battery life but the computer lets you when its low. However I have only used it in cold weather. It is very handy when riding around in the suburbs.
Review by Richard
Works like a charm!
Communicates with my Garmin well.
Does communicate twice - once for the radar and once for the light.
Virtually no documentation with unit.
Had to reference online documentation to figure out how to make light come on when you start a ride.
Decent battery life.
Picks up cars (and other cyclists) at a distance.
A must have if you ride on roads with cars

Love this light. Dead on accurate too. Synched up perfectly to my Wahoo meter.
Review by Robert
This product was exactly what i was looking for and needed. I feel more comfortable riding on the road now knowing when cars are approaching from the rear. Everyone i bike with also enjoys it because they also know when a car is coming. The light is bright and battery lasts for several rides. Great product would highly recommend to anyone.
Review by Go dog go
Up to 5 cars displayed each look like a lady bug crawling up the side of display . Typically picks a car up at 6 seconds back and triggers a beep on rural roads . Battery life is 2 ea 50 mile rides but should be longer . Weight and aero drag are minimal .
Review by Mike
My commute takes me on busy roads with a bunch of left hand turns so it's nice to know how I'm going to take that turn based on the cars from behind. This device makes it easier to determine if I take the lane or do a u turn on a perpendicular road. Very few ghost cars if any. Great safety device.
