Expert Reviews

  • Expensive when compared to other options.
  • Doesn’t have Bluetooth capabilities for extra functionality.
  • The size of the touchscreen isn’t the best for use compared to smartphone or the Edge 1000, reducing ease-of-use.

The Garmin Edge 820 Bike Computer is a feature-packed device that can help lead you in the right direction if you have planned a route ahead of time. However, if you veer off the route, your Garmin will struggle to help you. Despite this computer having numerous features for those tech-geeks, the lack of reliability, the inconsistencies, the expensive price, and the issues with the touchscreen have made this a bad choice for any level of cyclist.
