Our take on the Garmin Edge® 520

I'm a cyclist, and I've seen GPS cycling computers and smartphone apps revolutionize how we record and analyze our rides. And nobody has put the two together better than Garmin. If you're competitive — with yourself and others — you'll love the Edge 520 GPS cycling computer. This versatile device is compatible with Strava live segments, so you can track your progress while you're riding on your favorite climbs and fly zones. You'll receive alerts when the segments start and finish, and even instant leaderboard rankings once you've finished the segment.

For your competitive edge

I'm a cyclist, and I've seen GPS cycling computers and smartphone apps revolutionize how we record and analyze our rides. And nobody has put the two together better than Garmin.

Garmin Edge 520

Track your Strava segments in real time with the Edge 520.

Awesome smartphone integration

Edge 520 also taps into the power of your smartphone through the Garmin Connect™ Mobile app. Features like live tracking, social media sharing, weather, and more are ready to access before, during, and after your ride. When you're out on a long ride or race, your friends and family can follow your progress on Garmin Connect with real-time map updates. When the ride is done, you can share all the details with your circle of friends immediately.

Optimize your training

The Edge 520 offers the high-performance features you need for serious training. Its high-sensitivity GPS receiver records speed, distance, time, plus ascent and descent, while a built-in barometric altimeter yields precise elevation measurements. You can customize the Edge 520's screen to display the info that's important to you when you ride, so you'll always have the metrics you need right in front of you.

The Edge 520 works with all ANT+-enabled power meters (not included) so you can track your power output in watts when you ride — one of the most effective training methods available. And when it's paired with a heart rate monitor (not included), the Edge 520 tracks your heart rate, letting you train in the proper heart-rate zone to optimize your workout.

A new frontier in safety

Edge 520 is fully compatible with Garmin's Varia headlights, tail lights, and radar, ensuring that you'll know what's happening on the road around you, and that drivers are aware of your presence. You can quickly scope out threatening weather conditions on the Edge 520's water-resistant color display, while leaving your smartphone safe and dry in your pocket or jacket.

Garmin Edge 520 GPS

Anonymous from Bentonville, AR on 5/20/2017

I bought this Garmin for my husband a few years ago when it came out so that I would know where he was when he rode by himself out in the country. He had had a bad accident (hit by a coyote who didn't see him!) in the middle of no where. It was terribly expensive but I thought worth it to get. He has had nothing but problems with it connecting. They have updates all the time and don't say that's the problem. It works for him maybe 50% of the time. This morning it's not connecting again. We both wish I hadn't wasted the money on the thing. He is on the phone with the company wasting way too much of his time.



Good GPS

Work ok!

Pros: Good for use with Strava

Cons: Maps loaded on unit no good. Do like everyone download the free live street maps.

Excellent Performance & Reliability; Ok User Interface

Brad from North Jersey on 3/28/2016

Crutchfield Customer Review (What's this?)

I brought this to replace using my iPhone as a GPS/Cycling Computer as the batter would always die. Overall, I'm very happy with the Edge 520. It has a clear, crisp screen; picks up a GPS signal fast; connects to all my Garmin devices (heart rate, speed and cadence sensors), and works very reliably with a long battery life. That said, the user interface is a bit of a challenge. A touchscreen would make it MUCH easier but I understand that would make this device even more expensive than it is. Also, not having a touchscreen is nice in the colder weather as I don't have to take my gloves off to use the device. But still, the UI can be painful. You have four buttons to control a menu of options. Hit the wrong button and you may change something you don't want, or exit out of something you just spent a few minutes trying to configure. It's a small price to pay for a great device, though.

Pros: Reliability; lightweight; picks up GPS signal fast; connects to all Garmin sensors; pairs with phone for alerts and messages; allows use of Garmin Livetrack through phone

Cons: User interface; cost.

Garmin Edge 520 review

Pat from dallas, TX on 2/29/2016

Crutchfield Customer Review (What's this?)

I bought this to replace a Garmin 310xt that I have been using for several years. It's a well priced unit that offers mapping, courses, and all of the cycling data that you need. It offers almost all of the functionality of the 1000 at a much lower price, but with a slightly smaller screen and buttons instead of a touch-screen.

Pros: The screen is big enough to provide 10 readable data fields. Screens are easily configurable. Data upload is very fast. The basemap that comes with it is kind of worthless, but it is easy and free to uploaded detailed maps from OpenStreetMap. It's easy to turn previous rides into courses that can loaded on to the device. You can also create courses manually using Garmin Connect, or import courses that others have created. It's a nice compact computer with mapping at a reasonable price.

Cons: Garmin should have put a bit more memory into the unit so that larger map areas could be stored. The buttons on the side are not as easy to use as top-mounted buttons, but the remote control pretty much addresses this issue. The screen is easy to read in bright sunlight, but in shade it is not nearly as easy to read as the old 310xt (black and white screen). You can turn the illumination up to address this, but then battery depletion can be an issue on long rides.

I was very happy with the shipping to get here on time. And the gift was received with a great deal of pleasure. He is very hard to get for and loved it. It worked great for him on his first use.

Pros: On time shipping.

Hands-on research

Product Research


Overview: The Garmin Edge 520 is a compact, GPS-enabled advanced bicycle computer with connected features, such as live tracking, social media sharing, weather, and the ability to send and receive courses. The Edge 520 is waterproof (IPX7 rated), and comes with two standard handlebar mounts, and the Out Front Bike Mount, so you can mount it on multiple bikes.

Display: The Edge 520 has a 2.3" backlit, high resolution color LCD (1.4"W x 1.9"H), with a display resolution of 200 x 265 pixels. You can maneuver through the menus and make selections by touching the controls beside the display. The display will show your elapsed time, speed, distance, time of day, and calories burned (if applicable).

GPS: The Edge 520 has a high-sensitivity GPS receiver that calculates your position faster. When you turn on the unit outdoors, it finds satellites quickly, so you can start your ride quicker. The time of day and the date are automatically set by the GPS receiver. If training indoors, you can turn off the GPS receiver to save battery power.

GLONASS: In addition to the GPS (Global Positioning System), the Edge 520 is compatible with GLONASS (GLObal NAvigation Satellite System), operated by Russia. This gives the device increased performance and accuracy in challenging environments, and faster position acquisition. By default, the unit is set to GPS + GLONASS. For increased battery life, you can select GPS Only.

Strava: The Edge 520 is compatible with Strava, a cycling and running website and mobile app, which lets you set goals, training plans, get power analysis, and compare your results with other athletes in your age and weight class. You can download Strava segments to the Edge 520 for competing against your previous segment times, or others who ride the same route. Segment results appear in real time, showing the Distance to Go and Time Ahead (or Behind) your competitor. A free 3-month premium membership to Strava is included with the Edge 520 Bundle.

Smartphone Compatible: You can wirelessly link your device to a smartphone (Android or iOS) using the Garmin Connect Mobile app. At the end of your ride, you can transfer the ride data directly to your phone via Bluetooth. Using the app, you can analyze the details of your ride, or share it with others. You can also search out courses and workouts stored at Garmin Connect, download them to your smartphone, and send them to your Edge 520 wirelessly. Real-time weather updates and alerts can be sent from your smartphone to your device.

Live Tracking: Another connected feature of the Edge 520, Live Tracking, allows your friends and family to follow your races and training activities in real time. You can invite your followers via email or social media to view your live data on the Garmin Connect tracking page. Once they see your invitation, they can click to follow your progress on a map and see your stats.

Controls: Most of the controls are located along the edge of the display. On the Home screen, you can access your bike profile, change your activity profile, manage your history, courses, and workouts, and start a new ride. During your ride, you can use the front panel buttons to start/stop the timer and mark a new lap without having to look at the screen. The power and backlight button is located on the side.

Waterproof: The Edge 520 is waterproof to IEC Standard 60529 IPX7. It can withstand immersion in 1 meter of water for up to 30 minutes. The casing is totally sealed, including the front-mounted controls, and the USB port has a water-resistant cover to prevent corrosion.

ANT+: ANT+ is a wireless technology that allows certain accessories to communicate with the Edge 520. ANT+ sensors generally work within 10 feet of the unit. In addition, an increasing number of health clubs and fitness centers have ANT+ compatible equipment in their facilities, so you can use the same accessories separate from your device. Compatible Garmin ANT+ accessories include:

  • Heart Rate Monitor: When the Edge 520 is paired with the optional Premium Heart Rate Monitor, the unit tracks your heart beats per minute and calculates your calorie consumption as you train. You can train in a certain heart rate zone to improve your fitness level or compare your pace and heart rate to past performances.
  • Speed/Cadence Sensor: The optional Speed/Cadence Sensor measures your speed and pedaling strokes per minute. The Edge 520 has a Non-Zero Averaging option to let you include or exclude the zero values (when you're not pedaling) when calculating your power ratings.
  • Varia Bike Radar/Lights: Varia Rearview Radar and Smart Bike Lights work with the Edge 520 to keep you safe as you ride on the highway. Varia Rearview Radar can alert you of vehicles approaching from behind. Varia Smart headlights and tail lights integrate with the Edge 520 and change intensity with your speed.

Auto Pause: The built-in timer will pause automatically when it detects you're not moving. The timer will restart when you resume your ride.

Auto Lap: The Auto Lap feature lets you automatically mark the lap at a specific position. This helps you compare your performance over different parts of a ride (i.e. a long climb or training sprints). You can also use Auto Lap to mark laps at a specific distance.

Data Storage: The Edge 520's built-in memory (approximately 50 MB) stores at least 180 hours of ride data. The unit not only has an odometer to keep track of your mileage, but includes data on your last ride, longest ride, fastest ride, and all rides. Ride data can be sent to your smartphone via Bluetooth using the Garmin Connect app.

Note: The unit includes a basemap, but does not have the ability to add maps.

User Profile: The Edge 520 allows you to enter data about yourself to create a User Profile. This data (gender, birth year, weight, and height) is used to calculate accurate ride data.

Bike Profile: In addition to User Profiles, the Edge 520 allows you to customize ten bike profiles. In order to accurately calculate the ride data, the bike weight, odometer value, crank length, and wheel size are used.

Garmin Connect: Free web-based Garmin Connect software lets you store your workout data for comprehensive analysis. Garmin Connect is used by cyclists worldwide, and presents your data in an easily understood manner, with maps, reports, and suggested activities. You can create fitness goals and send them to your device. As you complete activities toward your goals, they are tracked on both the device and on Garmin Connect. In addition, the Garmin Training Center software lets you track and analyze your fitness activities and create workouts to send to your device, without requiring Internet access after the initial download.

Courses: The Edge 520 can save your ride data as you train. From that saved data, you can use Garmin Connect software to create courses that you can follow in the future. Each time you follow the course, the unit will compare your time to previous rides, or to other riders, and let you set performance goals. As you ride along the course, the display will indicate distance and time to upcoming maneuvers.

Virtual Partner: During your workout, you can use the Virtual Partner to help you meet your goals. The Virtual Partner rides along with you and provides incentive for you to keep up or stay ahead. If necessary, you can adjust the speed of the Virtual Partner during the ride.

USB Port: A Micro USB port is provided on the back of the unit for charging and connecting to your computer. A water-resistant cap keeps moisture out.

Power Requirements: The unit is powered by a built-in Lithium-Ion battery. It charges via the included USB cable when connected to your computer. The battery charge level is expressed as a percentage on the display. When using GPS + GLONASS, the Edge 520 will provide approximately 15 hours of battery life. Using GPS only extends the battery life to 20 hours. Using GPS + GLONASS with 100% backlight, the expected battery life drops to 6 hours. Extremely cold temperatures will also reduce battery life.

Mounting: The Edge 520 can be mounted to your bicycle's handlebars or stem. Two sizes of O-rings are included for best fit. Two complete mounts are included to allow you to use the unit on multiple bikes. The included Out-Front Bike Mount lets you put the device in front of the handlebars for easier, heads-up positioning and increased safety.

The Garmin offers no specific Di2 features or integration options. It is a self-contained product with a rechargeable battery so, it will work on just about any bike. I hope that helps. My Bio: [ Ryan  Aug 13, 2016 ]  Staff
