Garmin Edge 840 Review

Tested and reviewed for bikepacking use

Garmin's Edge 840 combines cycling computer metrics with serious navigation. The button interface works perfectly with gloves, and the mapping is the most detailed available. ClimbPro tells you exactly what's coming on every ascent.

Who Is the Garmin Edge 840 Best For?

Data-driven riders who want the most detailed maps and metrics. If that describes your riding style, the Edge 840 should be at the top of your shortlist. It sits in the Navigation & Electronics category alongside 7other products we've reviewed.

How It Compares

At 84g and $400, the Edge 840 is 15g heavier than the lightest option in this category (the Wahoo ELEMNT BOLT v2 at 69g). The most budget-friendly option is the Garmin eTrex SE at $150.

The price-to-weight ratio comes in at $476 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.

What We Like

  • +Physical buttons work with gloves
  • +ClimbPro for climb breakdowns
  • +Massive third-party app ecosystem

Watch Out For

  • Interface has a learning curve
  • Most expensive option at $400
  • Smaller screen than ROAM V2

The Bottom Line

The Garmin Edge 840 earns a 4.5/5 rating. It's one of the best options in the navigation & electronics category and a product we confidently recommend. The combination of best-in-class mapping detail and physical buttons work with gloves makes it stand out from the competition.
