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.

Incredible product!
Very well-developed product. Software and firmware works really well. New mounts are really well designed. Definitely a worthwhile purchase!

Rugged unit but half baked MTB features
No complaints about the tough, IP7 unit itself other than the buttons are weirdly, very hard to press. Luckily, the idea behind this device is just to set it and go? I love the screen and glass, it is bright and clear -- and battery life is acceptable if you generally plug it in when off the bike or completely power it down. It syncs up easily with my iPhone and also to my eMTB's LEV, pedal and speed sensors. It's fairly stable and hasn't rebooted/crashed since I initially updated. Here's some of the downsides/disappointments so far.. Most the MTB only features are half baked and don't exactly match the marketing. For example, 5hz downhill GPS recording mode is only available in a couple profiles and is not automatic. Timing Gates seem like a half baked feature: * There is pretty limited documentation and I didn't find setting of the gates very intuitive (which must be done on device), especially my first time! * You can only run one set of gates per activity * You can only compare against times in the SAME activity, you cannot compare times from any other activity or day. Even after the fact in Garmin Connect. * Gate series are not automatically detected and must do a bunch of button pressing and menu navigating to start. Apparently the single use case for the timing gates feature is lapping the same trail, in the same day, at least 3 times. (1st lap to setup gates, 2nd lap to set initial time, 3rd lap finally gets to compare). Map updates are DIY if you are using MacOS. There's no official supported method. Remember this device has no Wifi and updates must be done via USB. The new tube mount didn't fit on my eMTB, unfortunately. A longer strap would be nice. Lastly, e-Mountain and the new e-Enduro profiles are excluded from the segment or comparison features, even if you just want to race your own times. All in all -- I wish I waited on this device. And why are the buttons so hard to press?

Disappointed
I bought this Edge about two months ago, and it is actually my fourth Edge device from Garmin. I purchased this model without thoroughly researching its features and assumed it would have the same advanced functionality as my previous Edges. Unfortunately, I’ve been disappointed for two reasons: No Touchscreen – This was my oversight, but I was surprised to find that this model does not have a touchscreen and must be controlled with small side buttons. It makes operation less convenient during rides. Frequent Reboots – More importantly, the device sometimes goes dark and reboots during my rides. This is very frustrating, especially when I’m on busy roads. During the reboot, I completely lose my radar connection and have to stop and wait for the device to restart, which feels unsafe. I’m not sure whether this is a hardware or software issue, but it needs to be addressed. Overall, I have always loved Garmin products and consider them well-designed and reliable. However, this particular model did not meet my expectations, and I regret this purchase.

Edge MTB - Terrible
I bought this for the durability, but the functionality of the Edge MTB unit is terrible. I downloaded a file for a route I was suppose to take and it constantly put me off course. It kept getting an error and constantly told me to make a U Turn even though I was clearly on the route. Would not recommend.

Not For Me
Good concept but fell short for me. It is extremely small. Very hard to see especially if you have diabetic retinopathy and had eye surgeries. The buttons were extremely small and very difficult to use when riding. Navigation was useless and any warning was so small and lasted about a second so I could not read it. I could not get it to work with my Dexcom G7 even though I downloaded the CGM app and contacted the developer. Bought an SWMotech phone case and mount and another mount for my BMW GS motorcycle. I do use the Garmin speed and cadence ll sensors on my bicycle and use Samsung Health and either Trek Ride Club or Super Cycle depending on the occasion. And my Dexcom and Omnipod send me any low glucose alerts without a glitch.

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.
