Perfect bike computer

This is an upgrade for me from an older edge and it is amazing. My older Garmin was great when I first got it but after many years it started lagging behind technology. This device has all the whistles and with the solar option it really extends my ride time for ultra long rides. Highly recommend for anyone who needs reliability or all the techie stuff.

Returned Garmin 840 Solar
on June 6, 2025

My Garmin 840 experienced persistent issues from the beginning, frequently freezing during use. On multiple occasions, I was forced to restart the ride on the device. Notably, these problems only occurred when using the navigation feature—which is essential for my bikepacking plans this summer, as reliable navigation is the primary reason I purchased a bicycle computer.

Solar is amazing

840 solar is a game changer and in a smaller size computer compared to the 1030 or 40 etc. Love it. Does everything I need and more. Super simple set up from my Garmin profile. Just copied everything from my 530. Simple!

Great upgrade for me

I've used a garmin 820 for several years now and have been happy with it. But decided it was time to upgrade so after reading many reviews I went with the 840 solar. My rides are never too long but I thought the solar part would be a good back up in case I was out longer than usual. No issues so far and I'm happy with the purchase! Many thanks Garmin

Overall a great computer but still glitchy. Grade and elevation are definitely Off. Sensor glitch, I had to do a hard reset and reconnect all the sensors.

Replaced my Garmin 520, love the 840 solar. Battery life is excellent, especially w/solar technology. Still learning to navigate the screens love the touch screen it is awesome. This product is weel worth the money.
