Edge MTB delivers 5 Hz GPS, Trailforks maps, and advanced ride data in a rugged, MTB-ready design
What Our Gearhead® Experts Are Saying:
"I use the Edge MTB for both training and racing—it’s tuned for the demands of mountain biking. It nails GPS accuracy on rough descents, the jump metrics are spot on, and the new mounting options are dialed for trail bikes."
Purpose-built for aggressive trail riders, the Garmin Edge® MTB Bike Computer goes far beyond traditional GPS units. Engineered with a tough, compact chassis and scratch-resistant Gorilla® Glass, the Edge MTB stands up to harsh terrain, bar-bashing descents, and long days off the grid. Its 5 Hz multi-band GPS delivers incredibly accurate location data in enduro and downhill profiles, giving you precise feedback where it matters most—when you're dropping fast through variable terrain.
Preloaded with Trailforks and TopoActive maps, the Edge MTB offers a new level of ride planning and real-time awareness. Forksight mode visually maps out upcoming trail forks, elevation profiles, and return-to-start routes on a vibrant, glare-resistant display. Built-in sensors track MTB-specific dynamics like Grit®, Flow™, jump speed, and hang time, while split timing gates push your performance deeper with every run.
Integrated safety features such as incident detection and hazard alerts enhance confidence on remote rides, while group messaging, leaderboards, and Garmin Connect™ post-ride insights bring a competitive edge to every session. Mount options for both top tube and handlebar ensure clean cockpit integration. With a 14-hour runtime under strain—or 26 hours in saver mode—this unit is built for long rides, fast descents, and everything in between. The Edge MTB doesn’t just follow your ride—it sharpens it.

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.
