Upgraded from the 530
on February 18, 2024
Posted by: Anonymous
This upgrade was really worth it. The battery holds up well, and the UI of the touch screen was far more intuitive than the buttons on the side. Only have a few rides with it, but I'm sure it's going to be around for a long time. Paired it with the speed and cadence sensors and my Garmin Fenix for the heart rate monitor. Gives me all the data feedback that I need and the ability to install Trailforks to utilize the gps for trail systems I'm not familiar with is great.

Garmin head units just keep getting more features and are easier to use.

I haven't had the 840 for too long, but I am coming from multiple edge models and a Fenix6. I like the new interface with touch screen and setup was way easier as it pulled all of my information from Garmin Connect and my Edge 1030.

Excellent head unit
on February 9, 2024
Posted by: Claudio C
I have owned the unit for about a month now and absolutely love it. Great for new rides/routes especially with the mapping and climbpro functions. A little pricey, and the touchscreen may not be necessary, but I got the upgraded version for the NA and EU maps preloaded since I will be travelling to the EU more often.

Finally replaced my 820
on February 6, 2024
Posted by: Fast Gary
The battery life on my ol’ 820 was getting really bad. It was to the point where I would outride it most of the time, especially if it was cold out. I would run a cable to a power supply, but that’s kinda lame. It served me well. Kinda wish, no I really wish, the battery was replaceable. Oh well. The new 840 is pretty rad. I didn’t like that it was bigger at first, but now like it because it is. Bigger. I still don’t use many of the fancy gizmos, but really like the grade (kinda lags but whatever) and how it guesses what climb I’m on. Easy to plot rides from the device. Knows local climbs. All awesome. Before I would never change what kind of ride I was on, road, dirt, or mtb. Too many swipes away in some menu. Now that’s super easy to select so I’ll be doing that. The mtb setting tracks my flow and grit??? What the heck? Garmin says a grit score of 40+ is a hard ride. My first ride was a 251. What does a 251 grits get me? Yeah that’s all turned off now. Awesome little unit. Glad I got it. Wish I could have replaced the battery on the 820. You should get one.

Training and recreation done right
on February 5, 2024
Posted by: Patrick R
The Garmin, 840 is a highly adjustable unit and can be personalized with ease. I have two different profiles, one for recreation, and one for actual training. Amongst other units, this model has worked flawlessly. You can set it up to have less fields and more prompts for beginner or really add in more metrics for any expert or pro. I've invested into the full Garmin ecosystem, but you can use third-party if you would like.

I love that it came with mounting solutions.
on February 4, 2024

The GPS unit came with three mounting solutions to the bounce of the unit is on top of the handlebars in one out front. So I am able to have it on a stationary bike, My mountain bike, and a road bike. Without even having to buy more mounting stuff.

New addition to my Garmin family
on January 25, 2024
Posted by: Team Wahoo
I picked up a new Edge 840 as a replacement for a lost Edge 520. I gotta say that this new device has been a tremendous improvement over the 520, in every way. I love the option of buttons and/or touch screen. The menu is much easier to navigate. The sensors picked up immediately (I never did get them to connect on the 520). The wi-go upload is super. The form factor is roughly the same, but the 840 feels much more substantial. I recorded thousands of miles on the 520 and hope to continue with the 840.
