Until they come out with a lightweight armor plating for bike riders less than 18 lbs. overall, then you kind of need to keep track of what's about to crush you from behind. The Varia RTL 510 keeps you alive and lessens the possibility of becoming a hood ornament for some Yahoo with loud pipes and big tires or, sometimes worse, the silent electric vehicle. Wouldn't leave home without it because not everyone you are in front of on the road has read the relevant section of their state's vehicle operator's manual which specifically states you have a right to exist on the roadway. Good luck out there.

Nice safety feature

For long lonely dirt road gravel grinding this is a must have safety tool. It warns you when someone is approaching from behind. Works perfectly every time. Even tells you if another rider is approaching. When the wind is blowing this radar is especially handy - no more surprise blow by's from vehicles.

The 6 hour run time limit is pretty true so far, though run time will undoubtedly fade with use. For longer rides I turn it off when I don't need it. For example, riding on busy highways the constant alerting gets a bit annoying. At this point I don't use it on any road where I expect traffic - I just expect traffic.

I have this paired with an Edge 830 and works well. Been a couple of issues where it needs to be reconnected during the first minutes of a ride. Wife has one too, connected in the same way and she's had the same connection issue. Nothing cycling it on and off doesn't solve.

Don't really care for the multi piece mount. It works, even on bumpy single track, but I have no doubt I will eventually lose a piece or two. I have to remove the mount to put the bike in a stand, and I take it off to wash it too. Those little pieces and the O-ring are easily misplaced in a pocket, on a bench, the deck, the truck bumper... you get the idea.

Hey Garmin - make a simpler mount. See the Lezyne tail light stretchy rubber strap thingy as an example of good implementation of the KISS principle.

Helps me stay safe, at a reasonable cost. Glad I got it
by RCH

I really like this radar. I ride mostly on county roads around Fort Collins, with varying amounts of car and truck traffic. Many rides involve crossing the FC urban area. I use it with a Wahoo Elemnt Bolt, and see no compatibility issues. It is wonderful to know when a car is behind, and even nicer to know when the road behind is clear. There is an occasional false positive which clears quickly, it never misses an approaching car or truck. Occasionally a quickly-overtaking bicycle will show briefly, but it becomes easy to interpret how that displays differently on the Wahoo display than a car. Cost was $200, but eliminates the need for a $35 usb-chargeable taillight. So radar peace of mind for $165. Not cheap, but well worth the cost in my mind.

I bought one of these after my riding partner did and I am glad I did. This puppy works perfectly and when paired with a compatible Garmin head unit alerts you to vehicles behind you visually and aurally if you can hear well (which I cannot). I really like the way it starts blinking randomly and vigorously when approaching vehicles are detected. I HIGHLY RECOMMEND this unit and am absolutely delighted with its performance.

I hesitated to buy this due to the cost, but I finally got it on sale. I also hesitated because of the spacing on my bike between my seat pack and the tire position, but those are not a problem at all. (The instructions say it requires more space.) The light finds cars way before I hear them coming and it lets me know how close it is. The light has definitely made me feel much safer on the road. I usually ride by myself these days and often on rural roads, and I'm very glad I have the light.

by Anonymous

I bought this after getting hit by a car from behind despite using a rear flasher, after which I was riding more nervously. The device would not have deterred the stupid driver, but it has made me less nervous about approaching vehicles, and I am turning my head to check out what's occurring behind me far less frequently. I live and ride in a fairly rural area, on lightly trafficked roads. The warnings are flawless. I think that it would be less useful in urban settings.

I just got back from riding a section of the Oregon Coast Route. Much of the route is on HWY 101, a major highway with a speed limit of 55 mph much of the way (thank goodness there's usually a good shoulder). Having the radar function of this device to alert me to vehicles approaching from behind was an incredible benefit. It generally alerted me before I had even heard the vehicles and gave me a chance to pick the best line to hold to stay safe. I've never, as a driver, seen the lights increasing flashes as vehicles approach, but that sounds cool, too. This thing, a rearview mirror or some sort, and the brightest clothing you can find are probably your best bets for staying alive riding busy roads of any sort. A front flasher's a good idea, too.

Ingenious product and absolutely a peace of mind enabler. You are alerted to cars approaching from the rear on your Garmin head mount unit and it blinks in increasing cadence as cars approach to alert distracted riders to your presence. I would not bike without it.

This is a fantastic upgrade from your standard blinky light and communicates with your garmin head unit. You can hear the rear beep alert and see the number of cars on your garmin head unit. It adds another degree of confidence when on rural roads when one can be lulled into pacificity and the alert is a nice reminder that even remote roads have traffic, often faster than urban and with little shoulder the increased blink cadence of this unit as traffic gets closer is another enhancement for your safety. Wise insurance.

Game Changer
by Tedolph

Cleveland, OH

I was skeptical about this product as I have been riding with an eyeglass rear view mirror for years-why would I need radar? After reading some reviews I decided to give it a try. Boy was I surprised. I though it would be redundant with the mirror but boy was I wrong-they are complimentary. With the mirror, generally I had to hear the car first and then look with my mirror, or just look with my mirror before changing lanes. I can maybe hear the car coming 25 yards back so I get a few seconds at best to look at it in my mirror and decide what to do. This thing sees the car coming waaaay back there, more than a football field and gives me a tone. This tells me to check my mirror and now I have three or four times as much time to decide what to do. Now I know way before I get to the intersection how many cars aee behind me before I even check the mirror-situational awareness is vastly improved and with a whole lot less effort and drama. It is like having a buddy 150 yards behind you saying, "car back" and you can hear him. It is expensive but worth every penny. Get the cheaper model that just talks to your Garmin and save the $50.00.

A great help in a heavy traffic environment

I am a gravel cyclist in Ho Chi Minh City (Saigon), Vietnam. To get out into the Mekong region, we have to use various roads, highways, ferries, etc. Having this light has been a godsend. Not only is it incredibly bright, it last for our 6 hour Sunday bike rides. On the flashing mode it can last up to 15 hours.

As for the radar function, I am able to pick up cars and trucks at least 100 meters behind me. There is a small ball that moves up the screen of my Garmin Edge 520 giving me a general idea of how far and where the vehicle is in relation to me. The only fault I have found is that it doesn't always pick up motor bikes as quickly as cars and trucks. However, this might be due to the size of these, the fact that they only go at about 20mph or placement of the radar device on my bike. I am going to move it to the end of my bike rack and see if that improves things.

Second generation rear light.

I really like the improvements in the second generation of Varia. Particularly, the ability to select different patterns for the light depending on conditions, extended battery life, and it is much brighter. I have two concerns. One, the form factor is limiting in how one is able to attach it to the bike. On the original model, it was more compact and convenient. Second, and this may be a user issue, the light goes into pairing mode every time it is turned on.

Best $$ I have spent on my road bike
by Sushibarb

Worth every penny. In hind sight If I bought it again I would purchase the new version 515, which is BlueTooth. I am a MTBiker but love riding the Colorado mountain roads, but hate the cars!! I finally feel safe on the road and really enjoy my road rides now that I have the radar. Knowing way in advance when a vehicle is approaching so I am positioned safely and mentally ready. I like to ride with my friends side by side and now we can safely do that. The red light really warms the motorist especially when it starts flashing. I have had motorist stop to tell me how well they could see me and how great the light is. I wish I had the money to buy this for everyone. It�s so important to stay safe out there.

Brilliant tech, just works!
by TX-Scot

The light is very bright and the radar detection of vehicles approaching is very effective, if you go out on solo rides or with small groups on quieter country roads this is incredible good at giving you advanced warning of traffic approaching.

It typically gives you a warning of vehicles approaching about 10 to 20 seconds before you can hear them. Since I got this I have not been surprised by an approaching vehicle once, even on roads where the traffic travels at 50 mph.

The Varia works with a wide range of Gamin cycle computers, I use this with a Garmin Edge 520 and it works flawlessly with it but I was surprised to find it also works well with the Edge 25 I also have.

Overall its a great bit of kit, easy to use and definitely keep me safer while out riding around country roads.

I had the previous generation of this product and loved it. This one is even better. It's eye-catching and informative - even a bit too sensitive sometimes, identifying vehicles moving on a road parallel to me and a block to the side. No matter - better safe than sorry. I do not like the "rubber band" mount, but it has been secure even on some pretty rough terrain. It works great with the Stages Dash head units, too, giving you the option of showing on the right or left side of your screen. I like to choose the traffic side.

Never Leave Home Without It
by HalloweenEagle

This is now the equivalent of wallet, keys, phone if I'm on my bike. I can't imagine cycling on the road without it now. It's responsive and accurate and gives me a feeling of security in knowing if/when cars are coming. I prefer to ride in the middle of the road since I live in a rural area, and this picks up cars from far enough away that I have time to prepare accordingly.

Must-Have Accessory
by Velocrank
Southwest Virginia

I used to write off the Varia as gimmicky and unnecessary until I synced with a friend during a ride together. After the very next ride without the radar warning me of approaching traffic on my usual rural backroads, I immediately went home and ordered my own Varia. This thing is must have for any cyclist riding solo or in a group, on any road and traffic situation. The warning comes in plenty of time to prepare myself, and I really like that I can glance down at my Garmin 520+ and see how many vehicles are approaching via the number of dots on the side of the screen. The Varia also eliminates that "surprise" pass where you never hear the vehicle until it is already beside you. Great for windy days that drown out approaching traffic noise.
