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.
My first 520 lasted 1 year 6 months
It started to lock up and shut down during a ride.
Garmin repairs were $104.00 and $4.00 shipping back, they sent me a new GPS in return.
I couldnt wait a month so bike tires direct using there regular shipping had me one in 3 days great service.
In Garmin defense Im probably a super user I ride 14,000 miles a year and a lot twice a days in the early season and hooked on Strava as many 60 year old guys
I have two 705 GPSs for travel both are 6 or 8 years old only had to replace the batteries and you could replace the batteries $8.00 each Shipped
I guess Im just a Grumpy Old Man who remembers when stuff lasted longer than the Warranty
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 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 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.
Bought this to replace a Cateye Adventure, looking mainly for a grade readout. the Cateye display was too small for my old eyes to see, and I read that the Garmin screen was customizable. Don't know to what extent you can customize, but I created a 5 item screen with the slope large enough to read. It does not have an auto-start (except after pause), which I found out the hard way on my first ride. I live in a foothills area, and was concerned about the satellite reception, but so far, no problems. The total elevation is coming out less than Strava (my sprinter legs tell me that Strava is the correct one!). The unit is manufactured in white and black, but BikeTiresDirect did not give a color option. Turns-out, the unit rec'd was white (perhaps why they were selling it at $XXX). Oh well, can't have everything. Overall, I am happy with the device, other than the fact that Garmin stuff is way over-priced (what's their profit margin on their products? pretty decent, I'm guessing).
I bought because I needed something I could transfer between bikes easily and so needed GPS. To be honest I have done very little to take advantage of much beyond the basics. I haven't even changed the preferences on the screen of what I see when riding. I wish it was easier to hit a button to switch the data saving for which bike I use, but to be honest, I don't care enough to take the time to go into my data to do it manually.
As an avid road cyclist, I purchased the 520 having used a Garmin 500 for three years. I was ready for the smartphone connectivity as it was always inconvenient to have to wait to download the 500 by data cable to a computer. The 520 lives up to it billing with all the features I was seeking . The Live Segment feature is awesome. The feedback from the unit give me exactly what information i was needing to train properly. All I can say is great unit!
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.
Replaces my 510 that started giving funky altitude readings. Seems more reliable than my 510, and I don't miss the touchscreen (which seemed like a bad idea for sweaty cyclist fingers anyway). Navigating functions in the 520 does not seem as intuitive as the 510 and boo for the loss of a programmable odometer, especially for multiple bikes. Four stars for that loss of functionality, otherwise 4.5 to 5.
While I really liked my Edge 200, the 520 offers so much more. There are way more features (Bluetooth, messaging, Strava live segments just to name a few. The color screen is awesome, and the ability to add heart and cadence monitors is just the icing on the cake. All this in a package that takes up little space, just slightly larger then the 200. I so happy I pulled the trigger and got the 520. You won't be disappointed!
The Garmin 520 is a great device for tracking speed, HR and cadence. It's small and light, and the battery last for a long period time. I ride 6-10 hours a week and only need to charge the battery every 2-3 weeks. It's hard to use Edge 520 for map and navigation, so if you need to see the map all the time, Edge 1000 is a better option as other reviews suggested. However, Garmin Express is connected to Strava, so uploading the training log to Strava is always seamless. Overall, I recommend this device to everyone.
