Date Posted:18 February 2016 

Garmin is one of leaders in GPS technology that offers a range of cycling GPS aimed at different kinds of riders. The Garmin EDGE series has basic models that can track your time, speed, and distance, as well as advanced models that have features such as pre-loaded cycling specific maps and route navigation.

If you’re into cycling and would like to track your performance or capture data while you ride, a GPS cycling computer would be one of the gears you would want to have. Unlike a phone, the Edge GPS cycling computer works up to 8 hours without worrying about data or battery drainage. It also uses GPS/GLONASS satellites for fast and accurate location.

Given the number of Garmin Edge cycling GPS you can choose from, here are several things to consider which will satisfy your need.


For basic riders who simply want to get basic cycling data

Garmin Edge 20/25 GPS Cycling Computer

Garmin Edge 20/25

The Garmin Edge 20/25 is easy to use and captures essential stats from your ride, including time, distance, speed, total ascent and location. It’s one of the smallest cycling GPS available today.

It has Garmin’s Auto Lap, Auto Pause and Auto Scroll features. You have the option to customise two display fields with up to three data fields per page and create course navigation using Garmin Connect.

Garmin Edge 25 is similar with Edge 20 but offers additional features that includes the following:

  • Smart notifications (displays email, text and other alerts when paired with your compatible phone)
  • Bluetooth Smart for uploading completed activities, and downloading rides/courses through Garmin Connect (not for Bluetooth sensors)
  • ANT+ sensor compatibility to track speed/cadence and heart rate
  • Garmin LiveTrack
  • Speed and Cadence Sensor
  • Compatible with Garmin Varia Rearview Radar


For those who want comprehensive ride data and smartphone connectivity

Garmin Edge 510 GPS Cycling Computer

Garmin Edge 510

Garmin Edge 510 can measure the cycling metrics that most riders would want or need, such as distance, speed, ascent/descent and it gives the option of using a heart rate monitor, cadence and power meters using ANT+ compatible sensors.

You can create up to five different activity profiles which allows you to customise data fields and device settings based on cycling activity, such as training or racing. Simply swiping Garmin 510’s touch screen will set it up to show the data you need for that ride.

When you pair the Edge 510 with your smartphone and use Garmin Connect Mobile, you can get real-time weather conditions, use social media sharing and Live Tracking. Garmin’s LiveTrack, lets you invite others to follow your rides so they can view your live data on a Garmin Connect tracking page. The Garmin Connect Mobile app also allows you to wirelessly upload completed activities and download courses on your device.


For those who want advanced cycling data and smartphone alerts

Garmin Edge 520 GPS Cycling Computer

Garmin Edge 520

As the upgrade to the Edge 510, the Edge 520 has all the features of the previous version but with a high-resolution colour display. With the 520's high resolution colour screen, it now uses buttons for easier navigation through menus and data screens. Here are a few of the features the Edge 520 that aren’t in the Edge 510: 

  • Smart notifications (displays email, text and other alerts when paired with your compatible phone)
  • Advanced performance and power analysis, including new Time in Zone, FTP tracking, cycling-specific VO2 and recovery and cycling dynamics
  • Compatible with Edge remote control, VIRB action cameras, Varia bike radar and lights
  • Integration with Shimano Di2 electronic shifting (track your current gearing while you ride)


For those who want advanced training capabilities, routable navigation, and smartphone connectivity

Garmin Edge 810 GPS Cycling Computer

Garmin Edge 810

The Edge 810 is the upgrade to the Edge 800 and offers the features available in the Edge 510. It lets your switch profiles during a ride just by swiping the touch screen just like the Edge 510 albeit in a larger screen. The touch screen is resistive, which means that even with wet fingers, or with gloves, it’ll still respond.

The big difference that Edge 810 has over the models mentioned above above is that it has built-in basemaps and is compatible with optional detailed street or TOPO maps, so it can guide your ride for touring where you might need onboard maps and navigation. Maps in the Edge 810 are routable, which means it knows that if you missed that turn on a particular street you can instead turn right on another street and loop back.

As with the Edge 510, Edge 810 also offers connected features through your smartphone, including live tracking, social media sharing and weather. Edge tracks the data and sends it to your phone using a Bluetooth® connection. 


For who wants advanced training capabilities, routable navigation, and smartphone alerts

Garmin Edge 1000 GPS Cycling Computer

Garmin Edge 1000

The Edge 1000 is the flagship GPS cycling computer from Garmin. It has a robust 3-inch high resolution touchscreen which has an integrated light sensor to automatically adjusts for light conditions.

Where the Garmin Edge 1000 truly shines is that it offers the best in class mapping functionality and can give you street-level turn by turn directions. It comes with free detailed bike-specific maps which is based on the Open Street Map, a community sourced map set. With its Route Planner feature, you can create routes directly on the device using the map, POI and segments you’ve downloaded from Garmin Connect.

The Edge 1000 lets you pair multiple ANT+ sensors as you’d like (heart rate monitors, cadence and speed monitors, Vector power pedals) for as many bikes as you’d like. Just connect to the sensors you have enabled at the start of the ride. 

You can also create training pages with up to 10 data fields and use various activity profiles for quick and convenient transitions when you switch your cycling activity, such as road, mountain biking or touring. To further improve your training and riding experience the Edge 1000 uses Garmin’s Advanced Workout and Virtual Partner functions.

As you’d expect with Garmin’s top of the range Edge device, you can pair Edge 1000 with your smartphone to enjoy the connected features with Garmin Connect such as live tracking, sending/receiving courses, social media sharing, and weather. Edge 1000 is the only Edge device that can use Wi-Fi.

Similar to Edge 520, you can also take advantage of following functionalities.

  • Smart notifications (displays email, text and other alerts when paired with your compatible phone)
  • Compatible with Edge remote control, VIRB action cameras, Varia bike radar and lights
  • Integration with Shimano Di2 electronic shifting (track your current gearing while you ride)
