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.
by griley

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.

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.

Works GREAT! But I wish it had a longer range.

For years, I have ridden with a large mirror on my road bike. It has worked fine unless the sun was low behind me or the mirror fogged. In those situations, the mirror was useless. But in those situations (and all others), the Varia works great! Once a vehicle comes within range, you get an audible beep and the blip shows up on your Garmin. Very dependable. It picks up every vehicle. Relative speed and distance is very accurate.

So . . . why not five stars? Three minor nits 1. It occasionally gives you false positives. One cyclist I ride with triggers it as if he were a car - but just one. Nobody else. 2. I wish the light were brighter. 3. I wish the range were 1.5 to 2 times as far as it is. On roads with a 50 mph speed limit or above, by the time the Varia alerts you of the car's presence, it is upon you. I would just like to receive a few seconds more notice.

This is an amazing device for the price. \

Works well, but needs more mount options
by bkfeinberg

1 of 1 customers found this review helpful.

I've had this for about three months now. It picks up cars at a good range, but you do need to point it straight back, and for those of us who do long distance rides where we need a large saddle bag that is a challenge. I've been mounting it on the left seat stay when I do that, but then it doesn't point straight back or quite level. It's a pity that there aren't more mount options. Also for long distance, it would be nice if there was a mode where it just acted as a radar, and not a light. The battery could last much longer then.

Variable Radar
by Dave
Fort Myers

Originally I thought why would I spend $200 on a tail light for my bike? Well, so far it has been the best money I have spent. Cycling on the road has inherent dangers. With the radar I have a tool that lets me know what is coming up behind me. Combined with mirrors, it certainly helps.

The Radar Taillight v2.0
by John
Cycling Enthusiast
Minnesota
53 of 54 customers found this review helpful.

I had the original Varia Radar taillight and thought it was a great idea. I ride on rural roads that have high speed limits so I only get 5-6 seconds of warning before a vehicle is on me. So knowing what is approaching from behind dynamically is a huge advantage in safety for me.

The Original Varia Radar was great but it had three serious failings First, the taillight was all but useless and was far too low in power. Second, the form factor was all wrong with it being oriented horizontally and tending to interfere with my legs unless it was positioned perfectly. This unit fixes both of those problems. The Taillight is BRIGHT and works great as a daylight flasher. You can see if from a mile away and, as a driver, your eye is drawn to it. The form factor is vertical which solves the leg interference problem. So that's all good. Third, the head unit (available as a bundle) now includes a beeper so you get an audio warning of an approaching target as well.

The only reason I gave it 4 stars for value is that you really should buy the total package of a head unit plus the taillight. Garmin won't sell the head unit separately and should.

Excellent rear light and RADAR
by Anonymous

I hadn't considered this until I had trouble with cars on faster descents. The RADAR works just as I expected, and gives me enough warning time to look ahead on the road and choose where to bike, and to turn and take a look behind me. This is what I wanted, a reliable device that told when to look. I'd recommend this rear light for anyone.

Really is eyes in the back of your head
by Tom W
Daily Commuter

1 of 1 customers found this review helpful.

ust finished my first ride with the Garmin Radar synced to my Wahoo Element. Blown away with its capabilities. It really is eyes in the back of your head.

A few blocks from my house, the first car to come up on me from the rear triggered the orange LEDs across the top of the Wahoo screen. But they did not go off after the car passed. I thought maybe the device needed to be calibrated because I did not hear any cars approaching me. Then I looked in my rear view mirror and saw a few more cars approaching a half black behind me. Once they all passed the LEDs turned off.

Riding north on Sheridan road on what seemed to be an empty road the orange LEDs lit up. I heard no cars. Looking in my rear view mirror I saw a car about 1 and half blocks behind me. I decided to look in my rear view mirror and note when I could hear the vehicle approaching. I found I can only hear a car from about 100 ft behind me vs the Garmin Radar alerting me of a car approaching at about 800 ft.

Ive always thought that not wearing headphones let my ears be another set of eyes. But today the wind was out of the north at about 15 mph and I had a beanie on under my ski helmet. Bottom line you dont hear cars approaching from the rear until theyre about 100 ft away.

Having always worn a rear view mirror on my helmet I falsely believed that I would see rear approaching traffic. Today's Radar reality checked showed me I don't look in my rear view mirror nearly often as much as I should, which should be every 5 to 10 seconds. The radar proved to me I only look in my mirror infrequently or not at all unless I hear an approaching car.

With 15 minutes left in my 90 minute ride I noticed some car icons moving up the left hand side of my screen. Having not read the directions for the radar I was pleasantly surprised that not only does the radar alert you to the rear approaching vehicles, it shows you how far back they are. It even shows you how many cars are behind you and there relative distance to you. They move up the screen as the car gets closer to you

Additionally, it has a strobe light that flashes brighter when the car gets closer.

Mounting takes about 30 seconds with a rubber band seat post adapter.

Bottom line, I was really impressed with the Garmin Radar and would recommend it every cyclist, especially if you wear headphones.

Best safety accessory available for road riders

I am an active road rider in the midwest and ride generally on country roads. Varia gives you advance warning for cars approaching from behind. It has been 100% accurate an often notifies you of an approaching car before you can hear the car.

As an owner of the original Varia, my only real complaint was battery life. Version 2 has fixed that. The original was good for 4-4.5 hrs, I have yet to come even close to draining the battery on my new model. Might be a tad heavier (I haven't weighed it) but well worth the tradeoff!

If you don't have eyes in the back of your head you will benefit from this varia
by Sean V
Cycling Enthusiast

Likes the included mount fits on my pinarello aero seat post. It's fairly small but still very bright. It changes flash patterns and intensity when cars approach. It works seamlessly with my garmin 520 head unit. I ride with a small mirror on my glasses but this gives me MUCH earlier warning for approaching cars (and I'm not always staring at my mirror either). The radar works fabulously on smaller, more lightly traveled roads where you may not hear a car till the last minute. I find the display very easy to interpret. The form factor of the this model varia is nicer sleeker than the original model and works just as well.

Dislikes the seat mount is just a rubber band with a standard garmin quarter twist mount. The twist part feels very secure to me but the actual assembly tends to rotate on the seat post from time to time. It's an easy fix, even while riding but I'm not always paying attention. Getting it to pair the first time was a little dodgy (if I recall, I had to pair the radar and then also include it as part of a garmin light network, but it was only a one time issue)

Overall I now consider this to be an essential part of my daily riding gear.

Riding on country roads, cars can kind of sneak up on you. Especially the quiet hybrid and electric types. The radar, synced with an Edge 520, does a great job of giving a heads up on cars and trucks coming from behind. The light is super bright and has a bunch of different flashing sequences. It can be a bit finicky to get the radar working sometimes. I have to turn it offon along with the 520 to get it to sync up properly sometimes. Kind of annoying when youre trying to get going, or dont notice until cars are passing with nary a beep. But when its working properly, it is totally worth it.
