GarminVaria RTL515 Radar With Tail Light(Return to Product Page)

Safety on the road has always been a concern. As a result I often am twisting my neck to see if there are cars behind. This is especially true when I ride 2 abreast with a friend (I choose to change to single file if I know a car is behind). Yes I have tried every mirror option available (helmet, bike handlebars, etc...) none of them consistently gave me the confidence that I knew what was behind me.

But the Vario does what it says. An audible as well as visual warning, well before I can hear a car coming. It was 100% accurate-I was quite impressed. What happens when 1 car passes you? Well, the noise of the 1st car makes it impossible to be certain if there is another car or now, so you have to turn your neck, which invariably means you sway a bit (even if just a little) in your lane. The Vario addresses this too. The red warning lights stay on if there is a 2nd or 3rd car until all cars have passed-genius.

I am a Wahoo user and it paired just fine with my Elemnt Bolt, full functionality.

Why almost perfect? One of my concerns is the poor driver who may drift out of their lane and hit me (much more of a problem with Cell Phones). My preference would be to have a camera that would show me that a car was getting dangerously close so I could head to the ditch and have some control of the outcome. Radar can't do that. So it is not all I could want but it is a massive improvement.

Had I realized how well it works I would have bought it sooner. Game changer!

I have been using the earlier version of Varia Radar 2 for a bit over two years. I have been told by drivers, among them two FedEX drivers, that it is the most effective tail light they have ever seen. It was visible at a distance of more than a mile. It begins flashing as soon as a car comes within the radar range. I ride just about every day and I have never been surprised by a vehicle coming up behind me. My computer beeps and the display of the vehicle or vehicles approaching shows along the right side of my Edge 1030. I can judge the speed and distance of the approaching vehicle from the display. It really is a remarkable piece of equipment, and it sounds like they have made it even better. My unit will start giving me a low battery warning after about 4 hours on a ride. I have never run out of battery, but my rides don't usually last longer than 4 hours. The longer life battery is certainly not a waste. To give some idea of the sensitivity of the radar, I was once standing by the side of the road taking a break when a runner I had passed earlier approached. The computer beeped, and the display showed the runner approaching. That is pretty amazing. Yet, at the same time, when I have ridden with another rider, his presence is not noticed by the radar, only cars approaching us. The stimulus for the radar is something approaching, not something keeping pace with you. Recharge time is about an hour or less. It is, in my opinion, a necessity if you ride on the road. It will pair with most Edge computers and, also, with Wahoo computers.

I'd been leery of the price yet consistently blown away by the positive comments on the Varia and finally ordered it a few months back. The positivity is 100% warranted. I've used it in the dark, in the day and during large group rides and have found all the modes pretty fantastic. It may be a placebo effect but I feel like cars give me a wider berth since I've been using it, too. The best part is that you can relax and enjoy the quiet roads even more, knowing you're free and clear. About the same time you can hear tires behind you, the Varia detects the car coming and you can move over.

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.

After initially scoffing at the idea of the Varia radar as being yet another piece of electronics for the bike I finally grew tired of cars sneaking up on me and with a 25% discount from WesterBikeWorks finally pulled the trigger. I was an idiot for not buying it sooner. That's no joke. It's great getting alerted to approaching cars particularly on windy days where I can't readily hear them. I have the single radar paired to both my Garmin as well as my wife's so when we ride together we can both take advantage of it. The light is bright and very difficult to miss (and blinding on group rides when people don't set it to a lower intensity). The only negatives I've found is the included universal mount is so-so on my round seat post and will be replaced by the Garmin clasp type mount in the future. The other negative is you can't use it while charging, meaning on a long ride you need to be conscious of which light mode you're using so you don't run out of battery.

Bought the Varia RTL515 for my son, after first having experience with the 715 that has the rear view incident camera, on my bike. The camera on the 715 adds bulk and weight, and is only really useful to have video evidence if you happen to get hit from behind. The best thing about either light is the alert to your computer that there are cars or other bikes gaining on you from the rear. Saves your neck from having to check back as frequently, especially on aerobars. You get the alert on your computer much sooner than you would generally see the vehicles otherwise. Only reason I gave the 515 four stars instead of 5, is because my son ( who lives in another state, Oregon) reports that on his older Garmin computer, the alert is just an orange bar plus audio, whereas on mine I also see dots for each vehicle, as well as their relative distance from each other and me. I don't know if his just isn't synced correctly, if the radar on the 515 doesn't relay this info, or if it's just because his compatible Garmin computer is older, and just unable to show the approaching dots. But I know he likes it, as I do. If it's an issue with his computer, he can upgrade it, because the added safety feature is worth it.

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 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.

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!

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.

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!

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.

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.

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.

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.

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.

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.

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.

Love this light. Dead on accurate too. Synched up perfectly to my Wahoo meter.
