You’ll never get lost again with the new bike computer from Garmin

Easy to use, the new GPS bike computer from Garmin will have you finding your way through the maze of city streets and urban routes without needing to ask for directions.

The Garmin Edge 820 is preloaded with the Garmin City Map for turn-by-turn navigation and also gives you routable roads and bike paths, elevation data, points of interest and an address search.

You can even use roundtrip routing to let the Edge 820 select a cycling-friendly route for you, based on how far you want to ride. The 2.3-inch touch screen display with 200×265 pixels is easy to operate and the battery has plenty of juice, supporting up to 15 hours in GPS training mode.

Moreover, you can ride even when the rain is pouring down because the Edge 820 is water resistant, conforming to IPX7 rating.

With 16 gigabytes, the bike computer has plenty of memory allowing you to store up to 200 way-points or locations and up to 100 courses for racing or training.

Moreover, it can record up to 200 hours of your ride. The bike computer comes with GPS and GLONASS sensors as well as a barometric altimeter.

It also has builtin ANT+ adapter to connect to ANT+ sensor devices, such as Garmin premium heart rate sensor, cadence sensor and speed sensor. The data from these sensors will be displayed on the bike computer screen and can be used to increase your performance. With the addition of a heart rate strap, you gain access to a variety of physiological data.

You read your cycling-specific VO2 max along with a recovery advisor, which analyses your data and tells you how long you should wait before attempting another hard ride.

This connected system of sensors, accessories, cycling computer and postride analysis at Garmin Connect allows you to keep track of how your body performs from ride to ride.

The package comes with a standard mount and extended outfront for conveniently mounting the Edge 820 to your handlebars.

To get the most out of the computer you will of course need a Garmin Connect account so that your ride data will be stored and analysed together with your profile (gender, age, weight and height) for the Edge 820 to calculate calories burned. Once connected to your smartphone with a Bluetooth connection, the Edge 820 will also display text messages and calls you’ve received.

The Bluetooth connection with your smartphone also allows the Edge 820 to automatically send your activity to Garmin Connect as soon as you finish recording it. And you can also post an update to your social media network when uploading an activity to your Garmin Connect account.

The Connect app has a wide range of uses, among them sending real-time weather conditions to the Edge 820, searching for courses and workouts and sending status announcements during your ride.

Equally useful are the Bluetooth Connected feature’s LiveTrack function, which allows your friends and family to follow your races and training activities in real time, and the GroupTrack.

Once the Edge 820 is connected to Garmin Connect app, GroupTrack can be used to keep tabs on your riding buddies and they on you if you become separated from the group. 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 a wide range of Varia cycling awareness products, including rearview radar and smart bike lights.

The bike computer displays two main sections – navigation and training. In training, you can race against a virtual partner or the computer by setting a speed for the virtual partner.

The computer will display its position on the bottom half of the screen in relation to your current position. You can also race against a Strava segment or download a segment from the web to practice. You can create a workout for practice or download workouts from the web. You can also use the option of training indoors from the training option.

The navigation feature is fun to use if you like to vary your routes and displays a GPS map to guide you. During the test, I enjoyed biking in my neighbourhood using the navigation feature. The Edge 820 displayed the map of my neighbourhood correctly. I also tried riding for 16.62 kms with the training feature.

The bike computer calculated my average riding speed at 18.2 km per hour and maximum speed of 23.7 km/h and informed me I had burned some 660 calories.

The bike computer measured my average heart rate by syncing with the Garmin heart rate sensor at 136 bpm and my max heart rate at 149 bpm.

The bike computer synced with a cadence sensor and a speed sensor and reported that I achieved an average cadence speed of 64 rounds per minute and maximum cadence speed of 81 rpm.

The cadence speed increased in line with the speed of riding. It reported my average riding speed of 18.2 km/h and my max speed as 23.7 km/h.

Garmin Edge 820 is distributed by GIS at the suggested retail price of Bt19,900, which includes a speed sensor, a cadence sensor and a Garmin premium heart rate sensor as well as a standard and an extended outfront mounts.
