As you can see, there are several differences. Also, the Edge 1030 looks quite different to the other two. The Edge 820 and 520 are the same size and weigh almost exactly the same. They look like big, beautiful bike computers. The Edge 1030 looks more like a smart phone. All three have the sleek good looks and quality feel that comes with the latest offerings from Garmin. Below is a visual of the differences between these 3 Garmin Edge bike computers.
So How to Decide: Garmin Edge 1030 vs 820 vs 520?
All 3 are top-quality bike computers that offer a dazzling number of advanced bike training features. You can connect all 3 to a range of useful devices and sensors, such as heart rate monitors, and speed, power, and cadence meters. They all have access to both GPS and Glonass satellite systems, so they acquire a GPS signal fast. All 3 will record your bike rides and will wirelessly transfer your data to Garmin Connect (or Strava, which you can read about here). All 3 offer live tracking – which means designated people can track where you are. All 3 are very connected, with phone call and text message alerts. All 3 have beautiful color screens. But the prices are very different!
To simplify matters, I have summed up the 3 bike computers below.
The Garmin Edge 520, summed up
The Garmin Edge 520 has been widely hailed as the biggest leap forward in bike computers, ever. This model introduced new advanced performance and power analysis, including new Time in Zone, FTP (Functional Threshold Power) tracking, cycling-specific VO2 and recovery and cycling dynamics. All of these are now shared by the Edge 820 and 1030.
You can read the complete specs of the Garmin Edge 520 bike computer in an in-depth review here.
The Garmin Edge 520 has gone back to button control, not touch screen control. Personally, I prefer button control. Sometimes I find screen swiping doesn’t work perfectly, especially in the rain. However, the new Garmin Edge 1030 has solved that rain problem. Button control gives you complete control, all the time, even with gloves on. On the other hand, many people prefer touchscreen control (which is offered by both the Edge 820 and the 1030). Some people find they have become so used to touchscreen controls that it has become intuitive. If this is you, you may find that not having touchscreen control is disconcerting or annoying.
Important: note that the Garmin Edge 520 does not give you cycling-specific maps and cannot calculate routes for you. For that you are going to have to look at the Edge 820 or Edge 1030. All you get with the Edge 520 are the most basic of maps, plus breadcrumbs-type navigation if you download courses to it. Also, thanks to new software upgrades, it now has the incredibly useful feature of being able to give you turn-by-turn navigation prompts for routes that you devise yourself with an app and then download to it. This is shown in this video:

 |  |  |
In a nutshell, the Garmin Edge 520 is for you if you want absolutely premium bike training features in a small, light, affordable package, and can figure out your own routes. Plus, you are more into button control than touchscreen control.
The Garmin Edge 820, summed up
The Garmin Edge 820 is a massive upgrade on the Edge 810, and arrived with brand new features that had not previously been seen in Garmin Edge bike computers. These include Group Track, Incident Alert, Battery Save Mode and Stress Score. It was also rolled out with compatibility with Connect IQ from the start. Of course, the Edge 520 now has almost all of those features (except for Group Track and Battery Save Mode), and the brand new Edge 1030 shipped with all of them – and then some.
Of course, the Garmin Edge 820 has true turn-by-turn navigation built into it, right out of the box.
The Garmin Edge 820 offers a huge number of features, including advanced training options, great maps and turn-by-turn navigation, as well as connectivity with every possible sensor, and smart notifications. The Garmin Edge 820 is excellent for both bike training and figuring out routes, much like a car GPS. You can read a complete review of the Garmin Edge 820 here.

In a nutshell, the Garmin Edge 820 is for you if you want absolutely premium bike training features in a small, light, package, and you also want premium mapping and navigation features, plus connectivity with every possible sensor, smart notifications, and the latest apps. Plus, you prefer touchscreen control over buttons.
The Garmin Edge 1030, summed up
The Garmin Edge 1030 offers a dazzling array of features, plus great user friendliness. If you need high-end training metrics and high-end maps and navigation, connectivity with every possible sensor, and smart notifications, then the Garmin Edge Bike Computer 1030 may be the right bike computer for you. Also, the big innovation with the Edge 1030 is the improved battery life – you can read more about that further down in this post.
The Edge 1030 also has the largest screen of any bike computer. This makes it great for seeing maps with ageing eyes. It is actually half an inch taller than the Edge 1000, which was previously the biggest bike computer. A bigger screen is not only easier to read, but also a bigger screen makes it that much easier to work the touch screen controls (something I personally find quite important when riding a bike in the rain). Finally, the Edge 1030 has somehow managed to greatly improve touch screen control in the rain – something which some users complained about with the Edge 820.
Naturally, as with the Garmin Edge 820, the Edge 1030 has true turn-by-turn navigation built into it, right out of the box.

Will the Other Garmin Units Get the New Garmin Edge 1030 Features?
The Edge 1030 is the newest of these 3 new bike computers, and as such has the greatest range of features. But as always with Garmin, it is only a matter of time before most of those features are rolled out to the other units. I go into depth about these features, and when/if they will be rolled out to the other Garmin units, in this in-depth post comparing the Edge 1030 to the 1000. For those who don’t want to read all that, I prepared this handy little chart just for you – it summarizes the new Edge 1030 features, and my best-guess predictions.
| Improved Battery Life – 44 hours instead of 15 hours | No, it is a hardware change |
| Improved touch screen that works well in rain | No, it appears to be hardware related |
| Ships preloaded with the new Garmin Connect app TrainingPeaks | You can download this app from the app store to other Garmin units right now! |
| The start/stop buttons moved to the bottom of the device (facing you) | No, it is hardware |
| Additional connectivity via BlueTooth Smart | No, it appears to be hardware related |
| Improved Strava Connectivity – you can download routes automatically, plus it alerts you to nearby segments and updates you in real time | Yes, most likely in the very next software updates |
| New feature: Uses Trendline Popularity Routing for mapping. So it focuses on the routes most popular with cyclists, drawing from Garmin Connect's database | Probably not any time soon, as it is a unique selling point. But some time in the future, it will have to be shared |
| Notifies you of upcoming sharp turns when navigating | Perhaps, but it’s hardly a deal breaker either way |
| Rider to Rider Messaging with canned messages | Probably not any time soon, as it is a unique selling point. But some time in the future, it will have to be shared - for messaging to succeed, a mass user baser is required! |
| Dashboard of the new Garmin Edge 1030 is much improved | Unlikely |
| New controls area | Yes, most likely in the next software update |
| Improved, more aerodynamic out front mount | Yes, definitely. Of course, you will have to actually buy it ... |
Next I have more details on the major differences between the Garmin Edge 1030, 820, and 520.
The Major Differences Between the Garmin Edge 1030, 820 and 520, summed up
Do You Need Tons of Battery Power?
Probably the most important change in the Edge 1030 is the vastly improved battery power. It now has a claimed battery strength of 20 hours, as opposed to the 15 hours of the Edge 520 and 820. PLUS, it also has Garmin Charge, which adds 24 hours to battery life. This is basically an external battery pack that clamps onto the bottom of the Garmin out front mount, and seamlessly and automatically connects with the Edge 1030. This is an optional extra – it does not ship with the basic unit.
I have not been able to cycle for a continuous 44 hours to test this battery life … and I am quite sure I never will achieve that in this particular life time. However, I have always found Garmin battery claims to be quite reliable. Plus, the Edge 1030 has Bluetooth Smart, which is a low-energy way to connect wirelessly to your smartphone and upload data, and so use less battery power.
Also, both the Edge 1030 and the 820 have battery save mode. You engage this if you are worried about running out of battery power. The screen will blank out, but it will keep recording your ride. You can bring the screen back to life at any time. This extends the battery life by several hours, and helps keep the 820 competitive with the 1030.
Maps and Navigation
If you need a bike computer that comes with useful, cycling-specific maps, and which you can use for navigation as it will calculate routes and give you turn-by-turn directions, then you probably need to rule out the Edge 520. Only the Edge 1030 and 820 come with these advanced navigation features. The Edge 520 cannot figure out how to get to places. However, you can download a breadcrumbs route to the 520 and then follow that. When doing that, you can get turn-by-turn notifications, plus an alert if you go off course. However, it lacks the ability to “re-calculate” on the fly, which you may have come to rely on if you use a motor car GPS unit.
Also, the Edge 1030 uses Trendline Popularity Routing, which means that it draws on the massive Garmin Connect database to choose bike routes that are used by real life cyclists. You can learn more about that in this short video:
Touchscreen vs. Button Control
The Edge 1030 and 820 both have touchscreen controls, while the Edge 520 is operated with buttons. So your preference on this matter is important. Bear in mind that there have been some user complaints about touchscreen controls on the Edge 820 in the rain. However, the Edge 1030 has vastly improved in this respect, and performs really well in the rain. It is still hard to operate when wearing bulky cycling gloves, however.
Does Size Matter to You?
These 3 bike computers have quite significant differences in size and weight. The Edge 1030 weighs 4.8 oz (123 g), the 820 weighs 2.4 oz (67.7 g), and the 520 weighs 2.1 oz (60 g). The 820 and the 520 are identical in size and display resolution: 2.3″ diagonal screens with 200 x 265 pixels high resolution. The Edge 1030 is very noticeably bigger, with a 3.5″ screen, looking more like a smart phone.
One way in which the 1030 is superior to the Edge 820, is that the 820 has a substantially smaller screen (the Edge 1030 screen is 1.2″ taller). This means it is easier to see maps on the Edge 1030. This could be important if you have eyesight that is less than perfect. In fact, I find the Garmin Edge 1030 (and the 1000) are the only bike computers I can see without difficulty (with the exception of the much cheaper CatEye Padrone, but that of course is a whole different class of bike computer).
However, if you don’t have any vision issues (and seldom cycle for 44 hours straight) the Edge 820 offers a remarkable range of features in a substantially cheaper unit.
Micro-SD Slot
Of these 3 bike computers, only the Edge 1030 has a micro-SD slot for an external memory card. These are usually used to add on a whole lot of maps, for example if you were off to the Netherlands for a bike tour. However, the Edge 820 has 16 GM of internal memory into which you can download maps, so it is unlikely to be a problem. Bear in mind that you can delete maps you are not using, for example, if you immigrate. You can also download a limited number of maps to the Edge 520, but if navigation is a primary concern for you, you are unlikely to have an Edge 520.
Note that the Edge 1030 has improved on the Edge 1000, in that the micro-SD slot has much improved weather protection.
Cutting Edge Improvements on the Garmin Edge 1030
As you can see from the chart above, the Garmin Edge 1030 also has a range of improvements that are not yet shared with the other units in the range (and some of them never will be). These include using Bluetooth Smart for improved battery life, coming preloaded with TrainingPeaks, improved interaction and functionality with Strava, and rider to rider messaging (with other riders who have a 1o30).
These are all nice-to-haves, but none of them on their own justifies the higher price tag for most cyclists.
Bottom Line on Garmin Edge 1030 vs 820 vs 520
- Buy the Edge 520 if you don’t care about navigation, as it gives you all the training features you could want in a cheaper unit. UNLESS you really want touchscreen, in which case you might want to choose the Edge 820. Or unless your eyesight requires the bigger screen of the 1030.
- Buy the Edge 1030 if navigation is important and your eyes are not that great. Or if you want enormous battery power. Or if you ride a lot in the rain, as its touch screen works really well in the rain.
- Buy the Edge 820 if training features AND navigation are important to you, and you can manage to see maps on a smaller unit just fine.
It comes down to what you need and value, and how much you are prepared to pay for it. It’s a tough choice, but somebody’s got to make it!
Finally, for those who want every single detail, this chart includes all of the key features on these three bike computers.
