Garmin Edge 840, Compact GPS Cycling Computer with Touchscreen and Buttons, Targeted Adaptive Coaching, Advanced Navigation and More

The Garmin Edge 840 is a powerful and reliable cycling computer that delivers an excellent overall experience, especially for riders who value navigation accuracy, battery efficiency, and advanced training insights. The combination of a responsive touchscreen with physical buttons makes it easy to use in any weather, and the interface is fast, clear, and customizable. Value for money is good.

Fantastic product. So many features and easy operation. Great improvement to my old Edge 810. Really great product for cycling.

Moving up from my Edge 510 that gave up the ghost. If you've been in the Garmin world, this one is intuitive and familiar. A lotta $$$ but worth it.

I have been a Garmin user for many years. I love all their products. I have watched as their products have become more reliable and user-friendly. The Edge 840 is the latest, and in my opinion, the best of their head units. Everything works and works well. The wireless sensors, the rear radar unit, the front headlight, the HR monitor—they all work great together. Syncing up all the various components and sensors is seamless and works right, every time. As a bonus I can sync up my Dexcom G7 CGM and get instant glucose readings during my bike rides—no more fear of bonking during a long ride. The touch screen works great, not even raindrops, or perspiration, affects the display. The 840, unlike the 830, also has buttons which work effectively and quickly. The new GPS chip is far more accurate than in the past. The Climb Pro feature is awesome. The 840 has far more features that I could ever hope to use, but the features that I do use work exceedingly well. If you are deciding between the 840 and the 540, I would recommend the 840.

Works great and easily connects to sensors. I took 1 star away because the solar ability isn’t worth an extra $100. Unless you live in a super sunny area with no cloud cover and only ever bike during the hours of 12-4 pm, you just won’t get enough sun exposure to add any meaningful charge. The best I’ve ever seen is 5 min added on an 1:20 ride on a clear day midafternoon ride, but most days, the amount of extra charge I get amounts to less than a minute of battery life.

I have had the opportunity to put a couple hundred miles on my 840. It has been a pleasant upgrade from my 830 (which had about 25,000 miles on it before the faceplate started to separate from the device). While the 840 seems slightly dimmer than the 830, I have adapted to this attenuation and hardly notice it now. The screen of the 840 is sufficiently large and the display is bold and quite prominent. Overall, I am very satisfied with my purchase and am enjoying the device immensely on my gravel bike!

I’m really glad I purchased this. It exceeds all my expectations. After reading the reviews and watching videos, I nearly passed on the upgraded model with solar. I splurged as I’m a sucker for all things solar. I’m actually blown away that I’m getting 20% battery return in high sun environments. I had over 17.1% (20 min) gain on an almost 2 hour ride with sun and lots of shade from trees. The battery lasts for a LONG time. I would like to be able to do more in the app to customize screens, etc. The touch screen works really well and there are buttons for all actions if needed because of gloves, etc. I had a bit of an issue with loading the USA maps on it at first and had to finagle things a bit. Typical Garmin issues. Overall, a great product and was the sweet spot for me with all the options available. What a great buy. I’m very happy.

The operating system has been updated with the new style also on Fenix 8 and other models I'm sure. Both touch screen and a full set of buttons makes operation easier. Both the GPS and Heart Rate are noticeably more accurate. Even though the screen is the same size and same pixel count, it is more vibrant and easier to read. Upgrading from Edge 530/830 was a breeze since all the customized screens for different activities easily ported over with a single command. Overall a nice upgrade with zero complaints.

GPS top!!! Vendedor muito atencioso e rápido!

My device ceased to charge or work today. I assume their is a guarantee on the product and I am entitled to have it fixed or replaced.

Recibí el Garmin antes del día calculado (lo cual estuvo perfecto). Este ciclo computador tiene buenas ventajas sobre el 540: mayor memoria, pantalla touch que lo hace más sencillo de manejar, se puede ver más info en la pantalla... ¡Una excelente opción para entrenar y competir!

Excellent et pleins d'options. Facile à configurer.

Second Garmin cycling computer I have purchased. Great quality out-of-the box.
