Review: Great bike upgrade - 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.
Review: Awesome bike computer! - 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.
