I'VE BEEN USING THE 1040 SOLAR NOW FOR CLOSE TO A YEAR... WHEN THE NEW AERO BIKE ARRIVED I REALIZED THE 1040 DIDN'T QUITE CLEAR THE STEM SO I DECIDED TO TAKE THE PLUNGE AND SNAG A 840 SOLAR. FOR THE PAST 3 1/2 WEEKS I'VE LOGGED 1200 MILES ON THE NEW BIKE AND LOVE THE COMPUTER!

Tips for Using the Edge 840 Solar Bike Computer
Solar charging is designed to optimize and extend the battery life of the device. Solar charging occurs even
when the device is in sleep mode or turned off.
• When you are not using the device, point the display toward sunlight to extend the battery life.
• During an activity, scroll to the solar data page.
The solar data page highlights the intensity of the current light conditions and the accumulated ride time
gained from the solar energy, taking into account the current usage and battery consumption of the device.

Needs some tweaking
on September 30, 2023
Posted by: Contrebassiste
Most of the functions are the same as the 830 it replaced though the menus are a little different and require some relearning. I like the way it transferred most settings from one unit to the other during the upgrade.
My biggest complaint is the Fitness Age calculation difference from the 830 to the 840. On the 830 my Fitness Age was 55 or 56 (I’m 71 years old). My VO2 was in the top 10-15% for my age. I’m in the top ten for my age on almost every Strava segment I ride. I’m a little overweight but not obese. On the 840 it lists my resting heart rate as 93 even though I’ve manually entered it as 62 (and measured last week at the doctor’s office as 59). Suddenly my Fitness Age is 100. In less than two weeks I’ve aged remarkably according to the 840 even though I’ve actually put in more time and effort.
My second complaint is the maximum heart rate “calculation.” In the last seven years I’ve never gotten my heart rate over 154. One theoretical heart rate calculation says, at the age of 71, my max should be 149. The new 840 is giving me “new” max heart rates in the 160s even though the stats at the end of the ride don’t indicate anything over 134.
Just a few tweaks to the system might be able to make the 840 more consistent and as reliable as the 830 was.

one problem
on October 10, 2023
Posted by: tonyh
i really like the Garmin, especially the solar chargin. i had an old Garmin and the battery was really short lived. one problem we had which my bike shop had trouble solving was getting the power meter to pair with the device. it still is difficult but i have found that if i turn the device off and on several times it will learn how to pair.

840 is great, solar, not sure
on October 10, 2023

Admittedly I'm a Garmin fanboi. I'm fully invested into their ecosystem and I love the integrated metrics their devices provide, so I thought it was a no brainer to upgrade my Edge 530 to an Edge 840 Solar.
First, the good. The interface is great. It's very intuitive and things are as you would expect. Configuring data screens on your phone vs on the Edge itself is SOO much easier.
Full time ClimbPro, without have a route loaded. This is good, but it seems to have the bug that DC Rainmaker and GPLlama and a whole host of other Youtubers has described. It will often start well in to a climb and just be off. I'll be at a steep section and ClimbPro will show me at a mild section, and vice versa. Then I'll crest the top and it will show there are still a couple hundred feet to go. I'm confident this will eventually get fixed, but until then it's kind of just a gimmick, it used to be great when it worked.
Now for the Solar. I give Garmin a lot of credit for the innovations of adding solar, as far as I know, no one else is doing it and you can bet they are now looking at it. That said, it's not worth the premium. I live in Colorado, we have bright sun all day long here. I did a 2hr ride at dusk at 5pm, had the Edge flat like Garmin suggests, got zero solar time. Ok, so it was encroaching on evening you say? Well, I did a 2.5hr ride at 11am, in bright full sun, I got 14min back. A couple days later I did a 2hr 1pm ride in bright full sun and got 9min back. Not only that, but the solar screen on the 840 is dimmer in contrast, so you have to run a lot more brightness to see it, which sucks the battery big time. The battery widget now shows you estimated time remaining as you change brightness.
Overall, is it a worthwhile upgrade over the 530, probably, but not the solar, go with the non-solar. I do love Garmin and I was kind of sad to write this review.

Center of my Garmin ecosystem
on October 13, 2023
Posted by: F40_Endurace
I have the 840 Solar, HRM Pro, Varia headlight and taillight radar and I’ve been really happy with the system. The touch screen functionality is worth the extra cost, and the spray is a really cool feature. I like seeing how much time I’ve gained with the solar charging. The battery life is so good that I’ll probably never be in a situation where I have to rely on the solar power alone, but it’s fun to track.

Great improvements
on November 3, 2023

I think the option to have both the buttons and touch screen is a great option…especially during a race or riding singletrack. The UI is a nice an improvement with the added colors and features.
