Amazing Technology

I was a little skeptical, even after looking at u-tube videos. But wow, I'm very impressed with the technology. I bought it because I ride solo more than 50% of my miles (5000 - 6000 per yr), but it works equally as well with a group.

I use it with a Garmin edge 830. Love how it interfaces and shows me the approaching vehicles on my 830 head unit. Shows multiple vehicles. I have found it very reliable. Rarely do I get a false reading from another bike (only if our differential speed is significant). Definitely makes me a safer rider. Only wish - louder or adjustable audio alarm.

You need a blinky light, why not one that will reliably tell you if cars are approaching. I liked the first generation of the product. Some upgrades in styling. Must have product.

If only it could see around corners, or into the future...

I ride five or six days a week. I rely on the Garmin Varia Radar to help me see what's back there, coming up on me. I'm 72 years old, and it's tough to tuck and look under my arm like I did when I was younger. So with the Varia, and my rear-view mirror, I am more relaxed in traffic. Now, If only it could see around corners, or into the future...

At the beginning I was concerned with the battery performance but after using the radar in the blinking mode all my concerns went away. I have used this product on a 7 hour rides and it has worked great. You just need to be sure to use it in the blinking mode if not the battery last around 4 hours.

The radar info displayed on a supported Garmin bike computer is incredible

Paired with my Edge 520, this rear light alerts me when cars are approaching by showing RED highlights on both the left and right edges of the screen. Even better, on the right edge of the screen inside the RED highlight is a dot for each vehicle that is approaching you. Each dot starts at the bottom of the screen and slides up the screen as the vehicle is approaching you (moving up the screen faster if the vehicle is moving faster). Once all the vehicles have gone by, the left and right sides of the screen flash GREEN to let you know the cars have gone by. It feels so much safer riding on the road to know that a car is coming so that you can time your look back accordingly.

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.

Wonderful tail light. The radar works great. I have a Edge 520 and it can cause it to drain its battery faster. I had to adjust the back light to get it to last through all day rides. I sure a newer Edge would pair better. You can control the Varia with the 830 and old 520 does not have that capability. But other than that I love the unit and would recommended it.

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!

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.

I'm really impressed by how well the radar works in conjunction with my Garmin head unit (530), including showing multiple vehicles. I've found it very helpful when country roads rather than relying solely on hearing. It's also allowed me to signal to cars when it's safe to pass. I use another small light in conjunction (brighter, better battery life), so I'm also intrigued by their new 'radar only' unit.

Wish I could ride with this all year. In the cooler winter weather near Chicago, this unit causes my Garmin 520 Pluss battery to die early so I have learned not to use it in the winter.

There are two problems. The ding tone in the speedometer unit is not anywhere near loud enough and if your use the unit in the winter, the Garmin speedometer battery will go dead long before the ride is over!

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.

Radar (Garmin), great for situational awareness
rating
by ScottRidesAScott

This is a great radar that can track multiple vehicles approaching from behind. It also serves as a super back light with varying flash modes. I use my Garmin Vivioactive HR watch as my head unit, but you can use just about any Garmin device to keep you informed. I cannot believe I road so long without this device.
