Style: Edge 840
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. ... show more

    • Awesome bike computer!
Style: Edge 840 Solar
I picked up the Garmin Edge 840 Solar and I absolutely love it. Setup was quick and painless, and the Garmin Connect app made customizing my data screens incredibly easy. I have different layouts for different ride types, and switching between them is seamless. The touchscreen is a great upgrade. Swiping between views during a ride feels natural and makes it much easier to access maps, stats, and training screens on the fly. It is responsive even while riding. I went with the solar version, although it is hard to tell how much of a measurable benefit it has provided so far. The battery life is already excellent, so it is tough to say what percentage of that is solar versus normal usage. That said, the battery lasts a long time, which is exactly what I wanted. Overall, this is an awesome bike computer with tons of features, great battery life, and an easy-to-use interface. Highly recommended for anyone looking to upgrade. ... show more

    • This thing is amazing!
Style: Edge 840
Seriously, I'll never use more than 25% of what this thing does. But I'll never ride without it again. I have a profile for road and another for mountain. The customizable screen lets me see exactly what I want and need and nothing more or less. It's a bit fidgety to learn, you will need to spend some time, but it's so worth figuring it out. Sometimes I just go ride. I point at a landmark feature and just go. It has saved me from getting lost in the burbs and the wilderness many times. The return home feature is outstanding. Other times I look at google earth and plan a route that I've never been on before. Using Garmin connect on my PC I've been able to plot trails to exacting accuracy. Then upload them to the Garmin. I always end up where I think I will. Battery lasts for many rides, for me. (My rides are usually less than 25 miles.) My only complaint is that it's hard to talk some of my friends into buying one because of the price. In my opinion the price is justified. I wish my friends would take the plunge because another feature this device has is pairing with friends. They will become blips on your map. You'll never lose a rider again! Brilliant piece of kit. I've never used a cycling computer before but it's better than any app I've tried on my phone. even the one that came with my ebike. The Garmin automatically connected to my bike and shows me all the pertinent metrics. ... show more

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

    • Great computer
Style: Edge 840 Solar
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. ... show more

    • Feature rich. Garmin quality
Style: Edge 840 Solar
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.

    • Solar for the win
Style: Edge 840 Solar
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. ... show more

Review Image by Richard L. Grendell Richard L. Grendell
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! ... show more
