    Exclusive and accessorized.

    Regardless of the passion with which they argue against one another, one thing data geeks and anti-tech purists can't dispute is that with the right technology, numbers never lie. In the case of the Garmin Edge 520 Bike Bundle Computer, it's undeniably true. Drawing from Garmin's years of expertise in GPS and satellite technology, the Edge 520 houses dozens of honest numbers, neatly divided into categories to help you get a well-rounded view of your training. Invest in the 520 bundle and you'll have everything you need to get your 520 up and running and access most of the computer's potential data.

    One of the major ways Garmin separated the 520 from its lesser admirers was by equipping the computer with the ability to deliver live Strava updates as you ride. As you're slowed by the doldrums of the middle of a climb, no end in sight, look down at the screen to see how you're faring against your local rivals. Make note of exactly where you're starting to fall behind and change tactics if you can, then look down again at the top to see exactly where you finish as soon as you surge past the end of the segment.

    Aside from Strava addicts, the Edge 520 also caters to power meter worshippers, displaying functional threshold power (FTP) on-screen when paired with Garmin's Vector power meter pedals. While you ride, compare it to your ever-changing output and make mid-ride adjustments to keep your training effective. Take numbers like estimated V02 max, calculated using heart rate, into consideration when mapping out your training schedule and workouts, being careful to note recommended recovery time that the Edge calculates based on the effort level of each of your workouts. Recovery may seem like a no-brainer, but amateur athletes are often some of the worst offenders at overtraining. These new features are the big news, but don't worry — the Edge 520 still comes with all of the standard bike computer functions you've come to rely on in the saddle too, with a few signature Garmin extras.

    So Far So Good!

    • Familiarity: I've used it several times

    Like the title says, good so far. Not too big but packs in a lot. Helps you keep in the right zones and to not let up. Works with Strava as well.

    Easy to use

    • Familiarity: I've put it through the wringer

    I bought this computer to help build strength. I really like the HR band and being able to read my Rate as i am riding. It helps me keep a constant while riding and not slack off. The bundle is worth the extra buck. I also like that it syncs up with my Strava which even though it has its own app for tracking your rides i like to keep up on my starve account as well. I have yet to have a problem with the GPS coming off the handlebars. Love it.


      I love this computer. I have used it for years in races and training. It is better than the old edge 500. I use both power and heart rate while training and it allows you to view everything easily and is easy to upload to any training platform.

      It's all about the KOMs.

      • Familiarity: I've used it several times

      HA! The words "Steven Sheffield" and "KOM" will never really be found together except in the context of this sentence ... however, we all know that if it isn't on Strava, then the ride didn't happen ... right?

      I'll always end up using a dedicated GPS over my cellphone for tracking my rides; it's just more accurate that way. This is my 3rd Garmin, having started with the Edge 300, then the Edge 500.

      Love the configurable layout on screen, how vivid the screen is, and the ability to link to my phone via Bluetooth so I can see if a call or text is important enough pull over on the side of the road to take the call or respond to the text.

      I also like not having to keep track of yet another cable, in order to get my ride info uploaded to Strava, Garmin Connect, and Training Peaks.

      Still working on getting used to the button layout and learning all the features of the 520, but so far, I really like what I see.

      Two Different Review Locations?

        This seems dumb there are two different reviews (locations) for this product depending if a bundle or just the 520 unit alone. These reviews really need to be combined.


        • Familiarity: I've put it through the wringer

        I have had the Garmin Edge 205, 500, 510, and now the 520. Not gonna lie, I kind of miss the touch screen of the 510 even though it was not the most sensitive of screens. It did make navigating a little easier. And the 500 had adjustable volume, which I have also missed. But the 520 has a much sharper screen and only requires a few minutes to set up before hitting the road and trails.

        I upgraded from the 510 to the 520 purely for the phone notifications. I like being able to know if the text I just heard come in is important or not, without having to pull out my phone.

        The Live STRAVA segments is a pretty neat feature, although when riding trails I will get "off course" notifications due to the meandering nature of trail riding. On roads this has not been an issue though.

        Garmin is at the top of the computer game, quality built, accurate and easy to use. I have tried other bike computers and always come back to Garmin.
        Simply the best.

        Correction for Live Segments, I have realized that STRAVA Live Segments alerts you to any segments that you have "starred" on STRAVA. When I deselected the segments, I was no longer alerted to them, so my minor quibble was a result of my own ignorance of the feature.

        Love it

          After a couple weeks with this it really has helped my motivation to push it during intervals. Set it up for your favorite hills and the virtual partner really pushes you. On the uphill it's great on the mountain bike but I rarely look at it going downhill. On the road bike it's easy enough to see on ascent or descent.

          High expectation, adequate performance!

          • Familiarity: I've put it through the wringer

          Just bought this bundle. I've had it for about two weeks now. I was really excited about this computer, as I am a gear junkie; however, the excitement has died in the recent weeks. Why? the computer performs as described, but the directions (very few in my box) are barely sufficient. There seems to be several ways of accessing and performing functions. You can do it in one screen and realize that another screen will get you to the same place. The edge 520 is not intuitive and simple to navigate. Meaning, you have to play with it and familiarize yourself with the variety of functions and tailor it to your needs (courses, segments, displays). The map is barely functional, but (youtube's search of openstreetmaps and edge 520) it can be worked around. I gave it 3 star's because it is exactly that... "Adequate for the Job." If you buy this computer understand that it is a functional bike computer. Don't expect a $400.00 bike computer that will dazzle you, it will not happen. Lower your expectations and buy it for its ANT functions, GPS/GLONASS, and training functions. In all, I wish I was dazzled for $399.00. Lower your expectations and you should not be disappointed.

          NOTE: The screen can be difficult to see in certain daylight conditions. Mine came with out front mount and 2 additional mounts. A full descriptive manual was not included in mine.

          I have two bikes. I wonder if I buy a second pair of speed/cadence sensors, will the computer automatically recognize and pair with the sensor of the bike I choose to ride, or do I need to pair it manually everytime I switch bikes? Thank you!

          You simply create different bike profiles.. I don't know how many profiles you can have.. but I have three... each bike has its own sensors. When I switch bike, I just select the profile that match the bike I am using.

          Anyone have experience with a Garmin 520 and Stages power meter? I have a Campy Super Record Stages PM and a Garmin 500, and the signal keeps dropping out despite new battery.

          Is it the Garmin heart rate and cadence/speed sensors which are included? Or is it a generic?

          Hi Fredrik, the bundle unit includes a heart rate strap, as well as a speed sensor and a cadence sensor. The Bundle also includes an out front Garmin mount in addition to the standard mounts.

          Are you able to print out your workouts? My husband needs one that will be able to proven to get work credit for it. And if so does this one work on indoor trainers?

          Hi Gail,

          Workouts can be uploaded to sites like STRAVA or Garmins own Garmin Connect site. From there you can definitely print a screen shot of a ride / workout. As for indoor trainer use, if you have a speed / cadence sensor like the one that comes in the bundle, you can use this while riding on an indoor trainer and it will track your ride.

          how does the 'grade' function work? what are the data points it uses to calculate the 'grade'?

          Best Answer

          I believe it uses distance and elevation to calculate gradation. In my opinion it works well, but do not expect to get instant results. Meaning, it will take a second or two of riding to calculate the degree. On rolling hills I will notice that the gradient displayed will be already behind by 15 feet. This is not a issue for me and I consider it a reasonable deficiency and would be pressed to find a better computer that can display more accurate results.
