Why We Like The Garmin Edge 840 Solar Bike Computer
The Garmin Edge 840 Solar Bike Computer brings all of the features we love about the Edge 840 with the unique addition of solar charging. When charging in direct sunlight, our battery will last up to 60 hours, adding up to 25 minutes per hour while in battery saver mode to allow longer rides. When used with a compatible heart rate monitor or power meter, we are provided with adaptive coaching, personalized workouts, and stamina insights to help us gauge how much is left in our tank. Whether riding on the road, gravel, or deep in the woods on our favorite dirt trail, the integrated multi-band GNSS technology ensures we stay on the path with superior location accuracy.

Love it
I bought 3 weeks ago and do not disappoint. All features are great, and the touchless screen is fantastic. Great deal.

Perfect for me
I replaced my old 530. This is a definite upgrade. Touch screen is awesome. Solar charging is…ok I guess. I haven’t ridden long enough to see a real charge yet plus it is cloudy all day here in Michigan this time of year.

it works amazing
I bought this about a month ago but there is one thing that I cant figure out. I cant figure out how to make it estimate watts. Other then that it is a amazing piece of equipment.

GPS is super accurate but bugs
First I like the form factor, the buttons and touch screen are awesome UI is fast and routing is great. If I had to do it again I wouldn’t get the solar, the battery gain from solar is negligible, even on 100mi rides. And screen quality suffers from the solar glass. I wish the screen was bigger without increasing the overall shape, there seems like a lot of wasted space in the bezel. Room for improvement: The garmin struggles to sync with the phone after activities I have to close and reopen start and restart the unit multiple times before activities are uploaded. In some case activities aren’t uploaded at all. Other than that I love it it’s better than wahoo or hammerhead.

Same old Garmin issues
Ever since the 520, all Garmin units have had serious connection issues. 530, 830, 540 and now the 840. They all lose connections intermittently during the ride (frequently lose radar/phone etc. connections). After completing rides, they seldom sync without several tries and most often "forcing" a sync several times. Please spend less time on stupid features like pay and group stuff and fix the numerous and well documented connection issues with these units. The display is glossy and hard to see in direct sunlight and the touch screen is basically non-responsive. The solar is a completely useless feature. Again, please just fix the basics of these units first please before offering crap at a higher price that no one needs?

So many features
This is a great unit. The appealing feature for me was the Solar charging capability. It has so, so many features that, although good to have, is a little overwhelming to get yourself accustomed to it. Initially you have to spend a bit of time turning off and configuring it the way you like it. But the unit works great and the Solar charging is a huge plus.

Started great, doesn’t consistently connect….
Have had it for about a month. It regularly doesn’t connect to watch, di2, powermeter if left in sleep mode after saving a ride. But that’s the default for the power button. It’s annoying to have to fully turn it off and on each time when I commute daily and the battery should last at least a week in sleep mode. Could not find a fix on forums, Reddit or online.
