“Packed with features plus the ability to add third-party metrics and graphics; WiFi, Bluetooth and ANT+ means easy connection to your peripherals and quick uploads to Strava as soon as you finish your ride” – Bike Radar

At a Glance

Whether your goal is to beat yesterday with a faster or longer ride or dial in your training for a race, Edge 820 puts the features you crave at your fingertips. This compact, touchscreen GPS cycling computer offers advanced performance monitoring, bike-specific turn-by-turn navigation, our new GroupTrack feature and more.

GroupTrack for When You Pull Away from the Pack

Even when you pull away from the peloton, there’s no need to feel alone. Our new feature, GroupTrack¹, allows you to pair your device through Garmin Connect™ so you can keep tabs on your riding buddies, and they can keep tabs on you when you get separated. It’s just 1 of the innovations we’re rolling out to make your ride feel more connected.

The Touchscreen You’ve Been Waiting For

You’re going to enjoy using all the powerful features packed inside Edge 820’s compact body, but you’re going to really love the high-resolution touchscreen. An ambient light sensor automatically adjusts the screen’s brightness, so it’s easy for you to see at a glance, and the capacitive touch display is responsive — even when wet or used with gloves.

Advanced Performance Monitoring

Edge 820 GPS bike computer is compatible with ANT+® sensors, including speed, cadence and heart rate. For even more performance data, the 820 is also compatible with ANT+ power meters, including Vector™, our unique pedal-based power meter that measures total power, left/right balance and cadence. It integrates with ANT+ electronic shifting systems and ANT+ bike trainers. You can even record cycling dynamics to get a better look at your form, including where your power is being applied on the pedal and throughout the pedal stroke.

With the addition of a heart rate strap, you gain access to a variety of physiological data. See your cycling-specific VO2 max along with a recovery advisor, which analyzes your data and tells you how long you should wait before attempting another hard ride. This connected system of sensors, accessories, cycling computer and post-ride analysis at Garmin Connect allows you to keep track of how your body performs from ride to ride.

Navigate with Preloaded Garmin Cycle Map

Let GPS turn-by-turn navigation be your guide, whether you go on or off the road. Garmin Cycle Map provides you with routable road and bike paths, elevation data, points of interest and address search. You can even use round-trip routing to let Edge 820 select a cycling-friendly route for you, based on how far you want to ride, beginning to end.

Varia Compatibility for Increased Cycling Awareness

Edge 820 offers incident detection capabilities via an integrated accelerometer and sends your location to an emergency contact if you get into difficulty. To assist with incident avoidance, Edge 820 is also compatible with our wide range of Varia™ cycling awareness products, including rearview radar and smart bike lights for unparalleled awareness of your environment as you ride. See and be seen when Edge 820 is paired with these bike lights or the radar, which detects approaching traffic.

Can I pair my cycle computer with a smartphone, power meter and other devices? 

You will need a wireless computer to sync with other devices. Most wireless computers sync using 2 wireless technologies – ANT+ & Bluetooth Smart.

ANT+

ANT+ enabled devices to talk to each other and present the information on a compatible device.

Bluetooth Smart

Bluetooth Smart is a low energy wireless technology designed for smart sport and fitness. The long battery life in sensors makes it ideal for regular use in cycling. 

Always check your smartphone’s OS and 3rd party devices are compatible.

Would a Watch / Fitness band be better for me?

If you’re looking for something more versatile then cycle watches are a great alternative. You can still gather data from cycling sensors, but you can also gather data for different sports too. They are great for triathletes and those that do multiple sports. 

You can easily transfer data from a road bike to a mountain bike, from running to swimming. There aren’t many outdoor exercises you can’t track.

What software & Apps should I use?

Strava

Strava is perhaps the most well-known cycling App / software around. All you need is to record your cycling with a compatible GPS device, upload it to Strava and then you can analyse your data. You can compare your performance to previous efforts, your mates and even pro riders - all of this, for free.

Garmin Connect

All Garmin computers and devices will work with Garmin Connect. This is an online service that allows you to analyse your performance data, and share it with your friends. Reports show you how you’re progressing and you can use the calendar feature to plan your training sessions over time.
