Replaced a 520 plus. A real improvement. Much easier to see. Great battery life. Fun new features like the hill climb.

great upgrade
on May 11, 2023
Posted by: patas
I move up from 530 to 840 , the features and nice data like climb pro are a nice and way good upgrade, I added a power meter to my bikes and the data displayed in the 840 is useful, clear and value.
the battery performance is amazing, the 26 hrs plus is nice.
the best investment done!

High performance transparent gear
on May 13, 2023
Posted by: Dev D
I jumped into Garmin gear with a 530. Have had every version in between. The 840 does exactly what you expect. For me, gear needs to just be transparent and do its job and not worry about it. All the others have seemed to have little quirks that would bug. I had three different 830 and the elevation never worked right. If sweat or over foggy got on the 830 screen it was just a hassle to navigate. The 840 seems to have refined several things. I still hang on to the 530 because it is still a sid great unit that worked without any snags.
Garmin makes great gear and there really put out a great unit with the 840.
The real time climb is nice and can be adjusted for small, medium, large type climbs.

Great--but LOUD--replacement for Edge 1000
on May 14, 2023
Posted by: bhpowell
I bought this to replace an Edge 1000. The Edge 1000 still works fine, but it's so old it occasionally gets sensor errors with my Varia RTL510.
I was a bit worried about the 840's smaller form factor, but this hasn't been an issue. I usually ride with ten data fields showing, and the crisp display on the 840 works great. I don't miss the larger form factor of the 1000.
The 840 hasn't had any issues with the RTL510. The battery life is great. It seems to sync with my bike sensors faster. I like the new user interface--it only took a few minutes to get used to.
The only thing I could complain about is the overly loud beep alerts--e.g., when the radar detects an approaching vehicle. It lets everybody within a 100 foot radius that something is happening! I've improved this for the time being by putting a couple of small squares of gaffer tape over the speaker holes on the back. Now, the blast radius of the beeping is down to about 25 feet or so. I really hope Garmin lets us control the volume better with a firmware update--I'd like a loud bike alarm, but soft alerts for everything else.

Great for any Level of Cyclist
on May 16, 2023

I purchased this about a month ago, and am glad I did the research on which bike computer was better for my needs and wants (i.e. having a touchscreen, which does make a difference, compatible with my other Garmin products, and easy to install on my road bike.)

Leading edge technology in a small package
on May 20, 2023
Posted by: Qman
I bought the Edge 840 about 3 weeks ago and can't be any happier with all of the features that help me better train. At first the information can be a bit over the top but once you understand how to use it, it will become in valuable tool. I use the my computer for both road and mountain biking. You will not regret this purchase.

840 not what it's cracked up too!
on May 25, 2023
Posted by: Grumpy old man !
I bought the 840 because I have gad the 1000 edge and like the touch screen feature. It's much harder to use than the edge, can't figure out how to pause when stopped! It will not let me put in my own heartrate numbers! I realize it's user error, but I'm a cyclist not a computer geek. It is also harder for the touch screen to actually change.

Thank you for posting a review we appreciate it. It is possible to set up the auto pause feature and that should help with your recordings. Normally the heart rate zones are auto detected. We would also encourage you to reach out our team from our support site as well.
