Garmin Edge 800 In-Depth Review


If you are a bike rider or triathlete who trains on the bike, you probably use some sort of bike computer to monitor distance and speed. If so, most of you have heard about the Garmin Edge line of bike computers. Garmin, a leading maker in GPS products, started selling the Edge 800 in early 2011. The Edge 800 is Garmin’s top of the line GPS bike computer. The Edge 800 has a color touchscreen, which requires pressure to select times on the screen, and can be used with thin gloves. It comes with built in basemaps that show major roads and cities, and with an optional microSD card, the device is compatible with detailed street and topo maps. These additional maps can be purchased from Garmin, and can come preloaded on a purchased microSD card, or they can be downloaded and can be installed on a blank microSD. The Edge 800 also provides turn by turn navigation, just like your car GPS navigation system. You can use Garmin’s free BaseCamp software or other applications like Map My Ride to create a route, and then upload the route to the Edge. Once your ride is complete, your workout can be uploaded using Garmin Connect. It can also be exported to other software programs like TrainingPeaks.


Here is a quick introductory video from Garmin that shows some of the high level features of the Edge 800.

The Edge 800 has been out for a while, but since we are a newer website, this is a product that we feel is revolutionary, and we use it on a daily basis, we had to write a review to post on out site.

By  now, many of you have read the FitnessElectronicsBlog disclaimer, but here it is in case this is your first time reading one of our reviews. For the record, we do not work for Garmin, and are in no way connected with them or any of the companies whose gear we review. We do this because we love playing with the latest technology, and we can’t keep our hands off this stuff if we tried.  We purchased the Edge 800, and we have been using it for almost a year. No give-us-gear for a favorable review, or anything like that. We call ‘em as we see ‘em. It keeps us honest. Also, we have a group of 4 people who do the evaluations of all of the gear. One person is the lead on a piece of gear, but everyone gets a chance to evaluate the stuff. We have 2 guys and 2 ladies, so it’s a good mix of people. It gives us better insight, and we get a better review overall. Everyone has an input to the review. If you want to know who these people are, check out our About Us page. We have 4 seasoned triathletes, and 3 Pilates instructors. All swim, bike, run, do Pilates and Yoga, and use all of the gear on a daily basis. So, enough with the babble, and let’s get to the review.

What’s in the box?

First of all, the Edge 800 comes in two versions. The basic version retails for $449.99, while the bundled version with the additional heart rate monitor strap, cadence sensor, and data card with preloaded City Navigator retails for $649.99.

  • Manual

Edge 800 Bundled Version

Here is the box and contents of the basic model:
To get an idea of actual size, here are a few images of the 800:
The display is 160×240 pixels, which is adequate for the mapping screen.
The Edge 800 feels solid, and well constructed. There is a carbon fiber looking front panel that looks like a water transfer, and the back has a rubberized paint feel, with water resistant rubber connector covers:
To mount it to the bike, Garmin supplies their standard 1/4 turn mount. Here is a quick video on how easy it is to mount to your bike with the elastic bands and clip (this video uses the Garmin Edge 500, but the mounting hardware is the same):



If you purchase the bundled version with the speed/cadence sensor, here is a video on how to install it. It is very simple (once again, this video uses the Garmin Edge 500, but the mounting hardware is the same):

This device has an amazing number of features, screens, and data fields.

Using the Edge 800

There are three buttons in addition to the touch screen. The button on the left side is the power button. The left button at the bottom of the device is the lap/reset button. Pressing this button creates a new lap. If you press and hold, it will save your current ride and reset the timer. The right button is the start/stop button,. Pressing this button starts or stops the timer.

You can swipe your finger across the touchscreen to change pages, or to scroll.







When the device is first powered on, the stats screen is displayed. You can change bikes quickly, adjust the brightness, and lock the touchscreen.







At the top of the screen are icons that indicate ANT+  accessories. Pressing these icons takes you to the individual setting screens.


When you are ready to ride, press the start /stop button. Here is a typical screen that is viewable during your ride. You can customize data fields for five timer pages, with up to 10 items per screen. There is also the map page, Virtual Partner page, and the elevation page. Here is a shot of a timer page.








The data fields that can be chosen are almost too many to list, but I did anyway. Not all of the ones that I will list are available unless you have the optional ANT+ sensor:

Wow! There are too many choices. So you can set up to 5 screens of information with any of the data fields shown above. In addition, you also have the map screen, shown here.






You can create workouts in Garmin Training Center, or right on the Edge 800. If you create one in Garmin Training Center, you just upload the workout to the Edge. If you don’t have anyone to train with, you can use Virtual Partner (VP). Virtual Partner allows you to set a speed, and then Virtual Partner shows you whether you are keeping up. Here is a shot of the VP screen.






So, out of the box, set your data fields, press start, and you are ready to go. Here is a video on how to change the data fields.


Accessories and sensors

The Edge 800 is compatible with the following Garmin accessories:

Garmin Speed/Cadence Sensor





Garmin HRM Strap




Garmin Premium HRM Strap




The Edge 800 is compatible with Garmin Vector, Quarq, SRM, iBike, PowerTap, and other ANT+ enabled power meters. Here is a video that shows how to pair, calibrate and check that the power meter is working. This video uses a Edge 705 instead of the 800, but setup is the same.

Connection Software

There are multiple software programs that are made for or can be used to work with the Edge 800. Garmin WebUpdater updates the Edge 800 firmware and keeps it up to date, Training Center for analyzing your rides on your computer, and Garmin Connect for analyzing your rides on the web. BaseCamp can be used to plan and upload routes. Then there are the third party software options, such as Map My Ride and TrainingPeaks. Since some of these are in depth software programs, we will cover these programs in a separate blog post.

Thoughts, Opinions and Summary:

Overall, we think that the Garmin Edge 800 is the best GPS bike computer, bar none. We use it on a daily basis and think it is intuitive and easy to use. We typically would get 9+ hours of battery life in typical use. The size seems right, most of the time the screen is easy to read, and the mounting system works well. We downloaded City Navigator, and loaded it on a microSD card. The maps we very thorough, and we had no problems with navigating on backcountry roads. The training features were excellent, and we had no complaints with excluded features, or accuracy of measurements. If we had any complaints, and this is nitpicking, we think that Garmin Connect is good, but not great, and there are too many software programs when getting started. We would like to see one program that is easy to install, and does it all. For actual workout analysis, we are still fans of TrainingPeaks.

So the question we always ask is, “Would we buy the Edge 800 if it were our money that we were spending?” The answer is, yes. And we did. If you ride and train a lot, this is the bike computer for you. We have been using it for almost a year, and we wouldn’t give it up. If you don’t want the navigation feature, we would recommend the Edge 500.


  • Great maps
  • Screen visibility is good
  • Mounting system works well
  • Multiple options with cadence and heart rate options
  • Works with ANT+ power meters
  • Turn by turn directions are easy to use and read


  • Touch screen is tough to use when riding
  • Temperature is not always accurate, maybe due to self heating
  • Software options can be confusing
  • Garmin Connect web software is very good, not great
Happy Training
