The Edge 520 has everything I needed from a GPS at a good price. It has a water resistant build, easy to read and customize display, and compact. For me the deciding factor was having actual buttons (as opposed to a touchscreen) that allows me to use the unit in colder weather with full finger gloves.
I'm more of a casual rider, so I don't take advantage of the advanced features of the product. Having said that, there are some things that really bug me about it.
I primarily use it to upload my data to Ride wGPS. My biggest gripe is that when I'm done riding, uploading my data to the Garmin app via my cellphone rarely works wo rebooting my phone. I tend to use the latest and greatest Android versions (Nexus, Pixel), so that might be part of the problem. But the reboot is hugely annoying.
Lately the computer has been auto-enabling collision detection, and this goes off when I come to a controlled stop. I've since disabled it, but having the sirens go off on my phone at an intersection just irks me.
Finally, the Livetrack does work to notify my family of my rides, but sometimes beginning a ride it doesn't automatically turn on for 10 minutes or so nor does it always shut down cleanly after a ride.
I use it on all rides, auto-sync with Strava, syncs with HR monitor and power meter. Pairs with phone and shows when someone is calling or when a text is received (assuming you have service and aren't lost somewhere in the mountains..). Only complaint there is that when a text comes in it covers the screen (activity fields) and doesn't go away until you manually dismiss it by clicking a button. Yeah, picky, but I wished the text message would just dismiss after 10 seconds.
A handful of features I still don't use (and probably will never use).
Battery time is fine, nothing to worry about there. Size is perfect, out-front mount puts it in the perfect position. Buttons can be a little tricky to find/press when you're wearing full-finger gloves. But if you're riding with full-finger gloves then you have other problems to worry about.
The virtual partner thingy works, but takes a little to figure out at first. It's cool though to create courses from your own PR to race against.
Happens rarely, but I've had it completely die on me mid-ride when battery level is fine. Luckily it keeps a record of the ride, and after restarting the unit I can pick up where I left off. My brother (also 520) had the same experience once so I know it's not just my machine.
4 stars only because it's great, but not perfect.
I purchased the Edge 520 as an upgrade to my Edge 500. I like that it syncs with my iphone Bluetooth.
I also like that it can alert me to phone calls and text messages. I also find it easier to sync my heart monitor and speedcadence sensors between my two bicycles. At the end of the day the Edge 520 will upload to Garmin Connect, Strava and Ride with GPS.
I ride 4-5 dayswk, 175-200 miles - my Edge 520 is nearly as important as the bike itself. All the same great features of the 510 made better, plus better graphic presentations. And love the crash alert feature, plus textphone notices. Occasionally seems off on tracking instantaneous speed, but 510 had same problem which eventually went away, apparently through updates.
I ride about 150 miles per week. The Garmin has become a very useful tool. Haven't used the mapping capability yet but I like the unit. Does take some time to figure out if you're a newbie to Garmin. Plenty of YouTube videos for assistance though. Like the fact that the unit shows multiple items at once. No playing with buttons to scroll through information while you're riding.
replacing my old 510 which I lost, set up was great, took a little getting used to using the buttons instead of the screen. all was good for 2 months, then started getting crazy reading on temps, cal and elevation, would have 0 climb at end of ride. contacted Garmin, who said it was a bad barometer. since it was less than 6 months old, a new one is on the way. so that's cool...love the features of seeing who is calling or texting, lots of info screens you can set up...if the next one will only last, its a great computer...
Great Garmin Computer. Compact, easy to use, plenty of information recorded without being too much !
Very accurate, all the data you could possibly need or want.
I have used this bike computer for years and I do recommend it.
It looks great too !
I bought this cycling computer to replace my old Garmin 500. I love the look and the capability of this computer as it does much more and has bigger numbers which are easier to read for this aging cyclist. I am still learning to use this computer as it does much more and is more complicated as the 500 was simpler and easier to manage. Hopefully over the next few weeks I will learn how to optimize it's ability and be a better cyclist.
