Edge MTB Bike Computer delivers rugged navigation, split tracking, and trail insight for mountain riders
What Our Gearhead® Experts Are Saying:
"This device is an absolute game-changer for technical descents. The 5 Hz GPS is laser-accurate, even in dense forests, and Trailforks maps plus Forksight mode make route-finding almost too easy. It’s compact, super durable, and designed for riders who go hard."
Built from the ground up for mountain bikers, the Garmin Edge® MTB Bike Computer is as aggressive as the trails we ride. Its compact, rugged body is wrapped in scratch-resistant Corning® Gorilla® Glass, ready to face branches, grit, and hard crashes without flinching. With multiple ride profiles including enduro and downhill, the Edge MTB activates 5 Hz GPS for unmatched position tracking during fast, technical descents.
Before the ride, we scope out routes with preloaded Trailforks maps and TopoActive overlays. During the ride, Forksight mode helps us stay locked into the right line while timing gates give real-time split tracking to fuel progression. Post-ride, we dive deep into metrics like jump data, flow, and grit. Add group ride tools, safety alerts, and up to 14 hours of battery life, and it’s clear the Edge MTB is more than just a GPS—it’s a full-send trail companion.

A little cumbersome
I like this overall for abusive use. I wish it was a bit more intuitive on the use but overall I like it. A little clunky to get started.

A User-Friendly MTB Computer
Watched a few youtube videos, took the computer on a few hikes so I could concentrate on using its many features, and found that it's remarkably intuitive. The online user manual is also well written and organized. I think Garmin has created a great mtb computer.

It's perfect for my mountain bike!
I recently bought an electric mountain bike and am covering a lot of ground. The Edge MTB keys me make key junction decisions and it's rugged!

Love It!
Absolutely love this little computer. Highly recommend it. But, I also highly recommend reading the manual, unlike I did. Took three rides before I read it and finally got it.

Software is glitchy - freezes often
This was my first device. I did not research much and bought the MTB thinking that trailforks are pre-installed. However figuring out how to have a turn by turn directions and following a route is very complex and confusing. The Garmin courses is missing many trailforks trails for MTB and so you have to push each trail manually in the area you ride. The videos could have been more helpful on the navigation part.

Okay so far
I bought this model to try out not sure I i will keep. most likely not dont want to risk having issues with this model too. I have had issues with multiple of their products, multiple 540s, 840, and explore, so my expectations werent high for this device. Have only had for a couple of weeks and its been working fine so far, not like that meant anything before on their other products, theres just some features that I still dont understand how to use. I dont like how when in use my screen will change from my data screens to the maps and another that shows half map and half other data then shortly after will switch back to the original screen, It does this all ride.

Right Size, Rugged
I have a 1050 and when the MTB came out I figured I’d give it a try and reduce the risk and potential $$ of smashing that big computer on the MTB and gravel bikes. I was disappointed it wasn’t touch but the buttons are big and easy to use with summer gloves and I’m getting use to operating the thing. Screen is bright enough, plenty of MTB modes which I haven’t completely zeroed in on yet. One buggy thing is my power meter reconnects maybe a dozen times at the start of each ride. I even deleted and reinstalled and still an issue. It might be the PM or the Garmin - not sure - they are both new. All in all I’m glad I purchased. On the road I love the big screen of the 1050 and keep the map display up - great to anticipate changes in road at speed. In the woods, the big screen isn’t as needed but there is some data that I like having at a quick glance and this MTB hits the right balance.

Crash
The device crashes on the regular. I did a single 2 hour ride and it power cycled 3 times. It is so unreliable that it isn’t servings its purpose of helping my training. I’m not going to stop my ride to sort it out. It’s too distracting and counterproductive to my training.
