Not Happy
on August 6, 2025
Posted by: Gior
I have been using the Garmin 840 for the past year and a half. I could say there are some good features in this bicycle computer. However, the screen is always hard to read. It's always kind of dark. It is not very clear. That is my only problem with this bicycle computer. One of the things is that if I make it where it's really bright, the battery does not last as much as advertised.

Solar benefit doesn’t outweigh darker screen

I have had previous Edge models run out of juice on Century rides so solar seemed attractive, but I ride early morning/late afternoon a lot more than all day long and in fading light the screen is too dark. Lots of added features, but none that add huge value

Faster than my 830
on August 18, 2025
Posted by: JET3
I bought this recently to replace a lost 830. Although it is faster (processing) I don't like it as much. Had a few glitches with it - get prompts that don't allow you to complete what you were doing and at least once, I ended up in a loop that took dozens of tried to get past and shut down the device to start over.
I hope I get used to it and come to like it as much as mt 830.

Garmin Solar Computer
on September 5, 2025
Posted by: ricardo p
Garmin computer itself is great but I do not care so much for the solar feature of this computer. I don't feel it charges computer fast enough. Other than that the computer works great and user interface is easy to use. Also its very easy to connect other ant+ and bluetooth devices to be able to get all the data you could possibly need from your rides. Just wish the solar charged more while being used.

Really appreciate having the touch screen on this model

I've had a 500, 520, 840, and now the 840 solar. Main use right now is adventure riding so I really appreciate having the solar charging. I've found over the years that all the additional functions that have been added are more of a nuisance than anything so I go in and turn off all the notifications about upcoming climbs, Strava segments, fitness metrics, workout load, etc. Some of those were nice when I was heavy into performance on my road bike, using a power meter, etc. Now it's just plain annoying. I just want to be able to look down when I want info and not have to hear constant beeping, dismiss various notifications, be told there's a hill coming up when I can physically see it in front of me. I'm still rating this unit five stars because all that stuff is available if you want it and you can turn it off when you don't.
My favorite two things that I really don't want to be without is my Varia radar unit and the integration with Shimano Di2. As I've gotten older, I enjoy just riding at a more relaxed pace. Just built a carbon Salsa Cutthroat with Di2 and I love that you can use the two extra buttons on the hoods to control other functions via the Garmin. I have it set up right now so that the left hood button skips to the next song and the right button is a play/stop button. I throw a bluetooth speaker in my frame bag to enjoy some music while riding. I don't want to be "that guy" on the trail that disturbs the peace with music when other people are around so as soon as I see someone I can just hit the button on the hood and pause my music until I'm out of earshot of the other people. That all works through the Garmin so now I like the way things work together even more.

I love this cycling computer and how you can load routes in to follow. The solar recharging is super helpful as well.
