Pros & Cons

Pros & Cons

  • Ride even longer routes thanks to the battery that lasts up to 32 hours in intense mode (and up to 60 hours in battery saver mode).
  • The battery is charged as you ride by the solar panel in the screen, adding up to 25 minutes of battery life per hour during daytime cycling in direct sunlight.
  • The Edge 840 gives you insight into your VO2 max, recovery time, training load and physical response to training.
  • With daily suggested workouts, you receive personalised coaching that adapts to your current training load, recovery and events.
  • The Edge 840's internal memory is twice as large as that of the Edge 540 and includes not only maps of Western and Central Europe but also of Eastern Europe and North America.
  • To be able to use the livetrack functions you need to carry a cell phone.

4 / 5

Best device for navigation workouts and rhythm measurement.

- Marcel 16 June 2024

Upgraded from a wahoo bolt 1, it did exactly what you need a bike computer for. Only reason I wanted to upgrade is Garmin ecosystem (vario and hr) and much better navigation. Does exactly that one more, probably never going to get everything out of the device, but what I use m for. (Measuring ride, seeing traffic coming up behind and navigating) the unit more than satisfies. Compared to the wahoo, it is a more striking device, a lot bigger and heavier though, but I accept that, as the navigation is much better. And also controllable from the unit.

Pros & Cons

Good navigation, fast recalculations
Good readable screen
Integration with training apps and komoot
Solar function ensures longer duration.

Not cheap

- Martin 19 May 2024

Nice upgrade over the 830. The extra buttons on the side are very nice. Battery life is more than good. Screen to perform workouts is clearer compared to the 830. I did turn off the amount of notifications, got quite crazy with all the warnings for a turn, chance of heavy traffic etc.

Pros & Cons

Battery life
Screen size
Side control buttons
Recalculation if you go off a GPX route
