Garmin Edge 840 / Edge 840 Solar Touchscreen GPS Bike Computer

840 solar is a game changer and in a smaller size computer compared to the 1030 or 40 etc. Love it. Does everything I need and more. Super simple set up from my Garmin profile. Just copied everything from my 530. Simple!

So far so good. Really like some of the new functionality. Still learning and getting used to using the new features

My Garmin 840 experienced persistent issues from the beginning, frequently freezing during use. On multiple occasions, I was forced to restart the ride on the device. Notably, these problems only occurred when using the navigation feature—which is essential for my bikepacking plans this summer, as reliable navigation is the primary reason I purchased a bicycle computer.

Overall, this is a good unit. I like the amount of features that it has in the battery life. But I don’t like, is the clumsy/awkward menu layout that takes time to find things. I’ve had this edge 840 for about a month now, and still have trouble navigating certain areas. Today try to do a benefit charity ride in the rain and the altimeter stopped working a few miles in. Not the end of the world as the navigation still worked. But this seems like an issue that should have been fixed in the last version and it’s kind of frustrating when you are trying track stats and plan efforts on climbs. Wish I had known about the altimeter issue before I purchased.

When using the map the device crashes, it shuts down and after a while it turns back on. It's very frustrating as this happens almost every time you try to look at the streets around you, making it impossibile to find your curse if you get lost because the device keeps shutting down

This is an upgrade for me from an older edge and it is amazing. My older Garmin was great when I first got it but after many years it started lagging behind technology. This device has all the whistles and with the solar option it really extends my ride time for ultra long rides. Highly recommend for anyone who needs reliability or all the techie stuff.

Purchased this a month ago and it is fantastic! Extremely easy to operate

It has multiple issues with synching. I can see it in history, but it doesn't come over to the phone or laptop. Super frustrating.

This was a gift and I am just getting started learning the features. So far it has been pretty easy to load a route and save the ride. I need to make the font a little larger or at least define the contrast better. Let me know if that is possible

So far it’s amazing, I just need to get used to all of the features

Compatible with all you bike sensors and gadgets, great tool to maximize, track and improve your rides. Touch screen is a great advantage to toggle between screens during rides. Recommended

Overall this is a good device with lots of features, but the screen is very dim and difficult to read in either the dark or direct sunlight. The solar charging doesn’t offer much benefit either and the battery drains pretty fast.

*photo is of the the larger 1040 (or whatever #it is garmin, it was unnecessary for me and i prefer the 840). Plan ahead for time to sit down with necessary charging, WiFi, and account login information to setup the device. Once setup - it’s awesome. It lasted 6 days (lots of desert sun exposure) on the solar charging, had at least 6-10 different routes loaded, sharing information/updates/notifications, checking the screens/switching between screens for various metrics during long bike rides…idk how much more I could have been using unnecessary screen time with it, but it never died (#teamamerica). Also it does passively charge in the sun when it’s not in use! I’m keeping mine. Even though I wish it had more options/range for articulating how it sits on my drop bars. It’s not enough to negate the other advantages of it.

There is no doubt that the edge 840 is feature packed but it is unnecessarily complicated to set up and too prescriptive in terms of defaulting to workouts and performance rather than having those as a choice. Yes there are useful features but basic data should be there out of the box with anything else a matter of choice.

It's probably a no-brainer as to why this was a HUGE improvement! Everything works great, and the additional data has been very useful!

Too much white space, poor font makes for inefficient use of screen space. I find this to be much less readable than my Wahoo Roam 2. I've tried optimizing the screen content but can't fit as much useful data on the screen and still have it in a readable format. It's also missing nice touches like coloring gradient, etc.

It's a solid MTB cycling computer! It does everything I need it to reliably.

Nice computer with a lot of features (more than I have delved in to). It synchs easily with my iPhone via the Garmin app. The battery easily lasted for a 10 hours day ride at Leadville.

I bought this several months ago and cannot get Garmin Connect to recognize my device. I have tried everything…deleting and reinstalling Garmin Connect, installing it on a different computer, buying a different cable. Nothing works.

Good size and perfect tech to track my mountain bike and gravel rides.
