Edge 840, Compact GPS Cycling Computer

Big improvement over 540, largerColor screen i can see at night. Syncs quickly with Garmin iPhone app. Provides battery status on Shimano shifter, HRM, cadence, speed, radar, headlight. Easy to use. Get about 10 hours of battery between charges

Seriously, I'll never use more than 25% of what this thing does. But I'll never ride without it again. I have a profile for road and another for mountain. The customizable screen lets me see exactly what I want and need and nothing more or less. It's a bit fidgety to learn, you will need to spend some time, but it's so worth figuring it out. Sometimes I just go ride. I point at a landmark feature and just go. It has saved me from getting lost in the burbs and the wilderness many times. The return home feature is outstanding. Other times I look at google earth and plan a route that I've never been on before. Using Garmin connect on my PC I've been able to plot trails to exacting accuracy. Then upload them to the Garmin. I always end up where I think I will. Battery lasts for many rides, for me. (My rides are usually less than 25 miles.)My only complaint is that it's hard to talk some of my friends into buying one because of the price. In my opinion the price is justified. I wish my friends would take the plunge because another feature this device has is pairing with friends. They will become blips on your map. You'll never lose a rider again!Brilliant piece of kit. I've never used a cycling computer before but it's better than any app I've tried on my phone. even the one that came with my ebike. The Garmin automatically connected to my bike and shows me all the pertinent metrics.

I have been a Garmin user for many years. I love all their products. I have watched as their products have become more reliable and user-friendly. The Edge 840 is the latest, and in my opinion, the best of their head units. Everything works and works well. The wireless sensors, the rear radar unit, the front headlight, the HR monitor—they all work great together.Syncing up all the various components and sensors is seamless and works right, every time. As a bonus I can sync up my Dexcom G7 CGM and get instant glucose readings during my bike rides—no more fear of bonking during a long ride. The touch screen works great, not even raindrops, or perspiration, affects the display. The 840, unlike the 830, also has buttons which work effectively and quickly. The new GPS chip is far more accurate than in the past. The Climb Pro feature is awesome. The 840 has far more features that I could ever hope to use, but the features that I do use work exceedingly well.If you are deciding between the 840 and the 540, I would recommend the 840.

The Garmin Edge 840 is a powerful and reliable cycling computer that delivers an excellent overall experience, especially for riders who value navigation accuracy, battery efficiency, and advanced training insights. The combination of a responsive touchscreen with physical buttons makes it easy to use in any weather, and the interface is fast, clear, and customizable.Value for money is good.

A bit hard to navigate through it. Setting up a route is not user friendly, i gave up on it. Would be nice to be able to plan the route i want without the difficulties, i was excited to set up my routes on it but that quickly faded. Definitely a bit over priced all around. Size is okay, good and compact, seem durable enough. Connectivity is good so far.

The operating system has been updated with the new style also on Fenix 8 and other models I'm sure. Both touch screen and a full set of buttons makes operation easier. Both the GPS and Heart Rate are noticeably more accurate. Even though the screen is the same size and same pixel count, it is more vibrant and easier to read. Upgrading from Edge 530/830 was a breeze since all the customized screens for different activities easily ported over with a single command. Overall a nice upgrade with zero complaints.

I have had the opportunity to put a couple hundred miles on my 840. It has been a pleasant upgrade from my 830 (which had about 25,000 miles on it before the faceplate started to separate from the device).While the 840 seems slightly dimmer than the 830, I have adapted to this attenuation and hardly notice it now. The screen of the 840 is sufficiently large and the display is bold and quite prominent.Overall, I am very satisfied with my purchase and am enjoying the device immensely on my gravel bike!

I'm old enough to remember when Garmin was the KING of satnav.My, how times have changed.I picked this up as I was getting back into cycling and didn't want to risk putting my iPhone Pro on the handlebars if I didn't have to. Also I wanted to capture ride telemetry, using heart, cadence, and speed sensors.For something that just collects telemetry, records my ride, syncs it to Strava & Apple Health... the Garmin Edge 840 gets a solid B+.Things take a much darker turn when you try to actually use it to navigate anywhere. There's a cascading underworld of menus to go through to try to navigate to anything. But the play here really is to open your phone that you thought you wouldn't need anymore... go into the Garmin Connect app, set your start point and end point by tapping on them on a map (because place names or addresses might confuse it)... then fix the bad route it suggests because it'll put you on hiking paths that no bike belongs on. Or it'll dump you on streets with zero bicycle infrastructure when there's a perfectly good greenway path nearby.Then once you get going, there's a good chance it'll get confused and ask you to U-turn for no reason at all. Or lose track of where the next waypoint is. It's really comically bad at navigation.Now imagine if you're too young to have lived through it what 25 year old electronic devices might have been like to navigate. Then imagine what the Temu version would have been like, if Temu had been around. The user interface on the Garmin Edge 840 is like that. "Clunky" would be a bit too kind a word to describe it. The tiny screen size makes matters worse. Especially when it's very low resolution. And moreover, it has an auto brightness setting that is almost always too dark for the given ambient light.It works well with Ant+ sensors, no problem. It pairs with my phone, no problem. If you cut the number of buttons in half, and just made it more of a "ride recorder", then cut the price in half... it might just work. But for what it claims to be, utter failure.The sad thing is, the cycling industry doesn't know how much better it could be. So this is one of the best in class products out there. This is a really depressed class.I really wanted to give it one or two stars. But it's Christmas season. I'll thank it for the great job of syncing my rides to Apple Health + Strava, and give it a third star. Call it the Christmas star.But make no mistake... this stinks. I'm going back to putting my phone on the handlebar and hoping for the best. Because Google Maps *crushes* this. And I can sync the ride sensors directly to my Apple Watch and record my outdoor ride workouts from there. What do I even need this thing for?

My device ceased to charge or work today. I assume their is a guarantee on the product and I am entitled to have it fixed or replaced.

Excellent bike computer easy to program reliable and accurate course recording. Easily downloaded to you phone.

Pacco Arrivato molto in ritardo ma nulla da dire sulla qualità del Garmin 840 edge

The Garmin Edge 840 has exceeded my expectations. It’s easy to set up, the touchscreen is responsive, and the buttons make it simple to use even while riding. GPS tracking is accurate, the battery lasts a long time, and syncing with the app is seamless. The training metrics and navigation features are very helpful for both casual and long-distance rides. It’s a reliable cycling computer and well worth the investment. Highly recommended!
