Expensive, time-consuming to set everything up, but then lots of fun!

- Ricardo, 3 August, 2025

Much more convenient than navigating with a phone + power bank, and much nicer than looking at my (garmin) watch for relevant information during a ride. Setting everything up properly does take a lot of time, especially the fine tuning of your data fields, but when you have got past this, it really is a wonderful device. I am also very happy with the touchscreen. While biking, it is so handy to swipe a different screen. In the rain, it also worked perfectly.

Pros & Cons

Battery!
Data insight while biking
Loading routes via Komoot
Touchscreen! Also in the rain.
Setting everything up properly takes time

Recommended for road bikes

- Jeroen, 15 March, 2025

Coming from the Sigma ROX 12.0, there was a learning curve. But after some playing around at home and the first ride, I now know how to find everything. Convenient, fast and stable pairing with the app which is also very comprehensive. Long battery life.

Ideal bike computer

- Gerco, 17 December, 2024

Nice size. Not as big as an Edge 1040 and not as small as a 540. After several years of cycling without a bike computer, this is a relief. Display is clear. A phone display is much sharper but this screen suffices as a bike computer. The integration with Garmin Connect is very nice. I used to register a ride with my Garmin watch but this is much more convenient. All in all, a fine device.

Pros & Cons

Clear display
Integration with Garmin Connect is super
Not too big (1040) and not too small (540)

Top device for everyday use

- Stijn, 29 October, 2024

After an 820 and 830, now switched to 840. Very satisfied with ease of use of the garmin devices. For me, the 800 series is the ideal version. Small enough for everyday use (compared to 1000 series) but big enough for navigation (compared to 500 series). Ideal all-rounder. Fully adjustable to your own liking but this requires some trial and error. Checking which data should be visible when and how. Once set, it is super

Pros & Cons

Bright screen
Convenient operation (once set)
Long battery life
Setup to your own needs is a bit trail and error

THE bike computer/navigation to last for years.

- Anthony, 14 May, 2024

I was in huge doubt about buying another old 530 but ended up going for the 840. Very glad I made the extra investment for the touch screen. A real must in my eyes. Climbpro 2.0 is also a plus compared to the older versions. If you just follow someone without loading a route you can still see the necessary on the device. Only downside at the moment is that the connection to my watch for heart rate is permanently off and on. Currently no idea why. It is a Forerunner 245, so also from Garmin. Could also be due to watch itself, still to be investigated. In summary, a bit on the expensive side but touchscreen é Climbpro 2.0 do make it worthwhile.

The must-have bike GPS

- Marc, 30 April, 2024

I've just upgraded from the 820 to the 840. This GPS is really complete and very easy to use. The configuration transfer between the 820 and the 840 is really brilliant, as there's no need to go through the whole process of setting up the new GPS again. I'm also very pleased with its battery life (over 20 hours). The Climbpro function is very useful. It allows you to see the profile of a climb and thus manage your effort more effectively. I've still got a few things to test out, like the training sessions, but I'm already very, very pleased with it.

Beautiful design

Easy installation and synchronisation
Ideal size, not too big, not too small

Super bike computer

- Mathijs, 7 August, 2023

The Garmin Edge 840 is an excellent cycling computer with advanced features. The device performs excellently: route calculation is fast and even if you deviate from the route, the Garmin smoothly plans a new course to your original path instead of simply reversing. Battery life is impressive and the screen remains easy to read even in bright sunlight. The bright and responsive touchscreen makes navigation easy, while the accurate GPS and comprehensive map options are perfect for both road and off-road rides. The screen size is perfect in my opinion. The Garmin has an elaborate interface which takes some getting used to at first. Although the price is on the higher side, its excellent performance and reliability justify the investment.

Wonderful bike computer.

- Floris Jan, 20 July, 2023

Already made a few rounds with the Garmin Edge 840. You can see from everything that this is an important product for Garmin. Garmin has listened carefully to their customers and used all their experiences for this bike computer. The Garmin Edge 840 has a compact size, all kinds of buttons and a clear touchscreen. Installation is done within a few minutes, with the Garmin connect app connecting the bike computer to the internet. If you already have a Garmin watch, this is a piece of cake as it uses the same data. Also handy is to connect the Di2 gears and all kinds of sensors to the bike computer. During the ride, the bike computer is easy to operate, even with gloves. After the ride, you press the bottom button and the bike computer saves the data to the internet via wifi or mobile. Unfortunately, the bike computer does not have an e-sim, so it is still wise to bring the mobile along with the ride. The bike computer has a lot of possibilities, which is a bit far to discuss here, but on YouTube there are numerous videos about it. The price is one thing though, it is quite steep. The Garmin Edge 840 really adds something to your cycling experience, I'm going to do another round soon myself.

Clear and easy-to-read display

The usage is similar to the other Garmin. The touch screen is an advantage. With a downloaded manual, the Garmin 840 is easy to set up. Not yet able to try out all the functionalities in the first few weeks.
