Edge 840, Compact GPS Cycling Computer

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.

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.

Fantastic cycling computer. Bought this to replace my aged Garmin 520. The speed of the computer (not me) is much improved, as are the graphics and ease of use. Setup was also quite simple and I was able to use my existing sensors.

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.

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 had not bought a Garmin since the model 510. Back then I got rid of it due to the lack of organization of features and where they live (like having all sensor set up in one place, except for the heart rate sensor, hidden somewhere else). Garmin has been a sales leader in bike GPS for a long time. But there user interface has always been pretty horrible and non-intuitive (poorly organized as well). The crazy thing is—long time Garmin owners do not see it. They have memorized the UI/UX. New owners struggle to learn where sensors and settings are. If you figure something out, but do not ride for a few days, you cant remember where a setting is. Especially if you move the computer between different bikes. Having said all this is why I swore off Garmins after the 510 (including its short batt life). Now to the present: I needed a new bike computer. the Bike shop owner shows me a Garmin 840. "Its the greatest thing since sliced bread!" He convinces to buy the 840, even though his shop is out of stock. Says the UI is improved. Im like "no! Garmins typically have poor UI/UX. Their Devs are too close to the code." Long story, short: I let the bike shop owner convince me to try again. So I bought the 840. After the first ride I was convinced i'd been duped. The unit was trying to think for me. I just wanted to initially see my power, cadence and speed numbers. But no. it had all kind of things turned on by default. and on the trail or road you cant figure out how to fix it. I lost a couple of rides due to it not working correctly and not being able to get out of some of what the screen was trying to display. Also, when there is some sort of error, it displays it in the tiniest font. I could never find how to make an error message font/typeface bigger. There are way more issues then I can recall to write about. I finally sold it and bought a Wahoo Elemnt. Way more intuitive. I Have not yet lost a ride or struggle to define a sensor or even check the detail settings of a sensor (At least the HR is consideed asensor nowa. Of course I sold the 840 to a long time Garmin customer, so he has all of his Garmin-isms memorized. Me...I was disappointed that Garmin had not really improved their device usability in 10 yrs. But it is jammed full of a ton of stuff. Of course, if your eyes struggle with near-sighted vision, as some of us are born with and others have the sight isssue come on in their 40s, reviewing notifications and errors will be a struggle. The garmin is definitely not for you, regardless of the UI/UX.

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!
