  • Great bike upgrade
Style: Edge 840 Solar
Bike computers all have a ton of information these days. I have been using Garmin units since the Edge 500 and they have always been rock-solid. I upgraded from an Edge 530, which was a great device for both road and mountain biking because a couple of the features of the X40 line caught my attention. The main one was the automatic climb pro feature. The older units have climb pro, but only if you are following a course. 95% of my rides are not following a specific course and with the new Garmin, it will recognize that I am going uphill and give me the distance to the top of the climb, the average and instant grade, and track my progress. I find that super helpful as I try to motivate myself to push a little bit harder. The other feature that I liked was the road hazard notifications. If other users report a pothole or other hazard, it will alert you as you come close to the area. It works great. I find the screen size of the device is big enough for me to see several data fields and I like how easy it is to read. The battery life with the solar is outstanding. I did a 200+ mile ride and used less than half of the battery. The value is great if you ride a lot like I do. I actually like the older display a little better than the newer 850 version and it has all of the same compatibility. I am super happy with my purchase. ... 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

  • Best Garmin head unit yet
Style: Edge 840
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. ... show more

  • 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.
