Garmin introduces the Edge MTB not only presents the first bike computer developed explicitly for gravity mountain bikers. In contrast to its larger siblings, the sat nav is also Edge 1040 (pictured below) or 1050 much more manageable. More on whether this is an advantage or disadvantage in a moment.
According to the manufacturer, the device is aimed at enduro and downhill riders who require precise data recording and robust technology. The Garmin Edge MTB has special activity profiles (enduro and downhill in addition to the usual ones) and can record tracks with 5 Hz GPS technology. According to Garmin, it has a battery life of up to 14 hours.
The design emphasises durability. The compact housing uses scratch-resistant Corning Gorilla Glass, which has to withstand branches, mud and gravel. The device is certified to IPX7, meaning it is even waterproof when submerged in 1 metre of water for a maximum of 30 minutes.
The display is small: 44 x 33 mm (2.13 inches) visible part. The Edge MTB is therefore another Garmin computer that relies entirely on button operation. Seven buttons on the left, right and bottom allow operation even when wearing gloves. The colour display remains easy to read in the sun - provided you ride it with at least 70% brightness and without the automatic adjustment or switch-off.
Precision in track recording
According to Garmin, the 5 Hz GPS recording of the tracks records five data points per second and enables high-precision track recording in the Enduro and Downhill profiles. This high sampling rate improves accuracy on fast changes of direction and steep sections. Multi-frequency reception ensures a stable signal even under dense tree cover or in narrow valleys.
Trailforks integration & navigation
Pre-installed Trailforks maps provide access to worldwide MTB trail data. The ForkSight function displays details of the distance, length, altitude metres and difficulty level of the planned trails before the ride. This information helps with tour planning and estimating the time required.
Trendline Popularity Routing finds the most popular routes of other Garmin users in the region. TopoActive maps show tarmac and unpaved paths as well as busy roads for navigation between trailheads. The bike-specific route guidance takes cycle paths into account and avoids motorways.
MTB dynamics and profile differences
The MTB dynamics analyse grit, flow and jumps during the ride - already familiar from the Edge 1040. These metrics evaluate difficulty, riding dynamics and airtime for detailed run analysis over a beer or spritzer afterwards. The Enduro profile shows altitude and depth metres for both individual runs and the entire activity.
The downhill profile automatically saves every run and restarts as soon as the rider gets on the lift or shuttle. This automatic function separates descents from ascents and creates separate statistics for each section.
The Garmin Edge MTB in practice
We first took the Garmin Edge MTB out on our home trails and then to the Willingen bike park. First of all: Until the last software update 28.20, we repeatedly had the problem of the device restarting completely every 20 minutes or so.
This meant that navigation was not possible for about 1 or 2 minutes while riding, the recording was activated as if after a break and the mode in the enduro profile (descent / ascent) had to be reselected.
The battery performance also suffered from the restarts, so that a maximum runtime of 5 or 6 hours was realistic, which usually exceeds a day in the bike park. During the last test ride in the bike park, everything was normal and - to start with - the battery runtime was even better after the software update.
Operation with buttons?
In general, you have to get used to the button operation again a little - to zoom the map, for example, you first have to hold down a button for longer, then plus and minus appear on the display.
And you often have to zoom in when you're not in the bike park because of the size of the display. If the display for the Climbpro assistant and a warning about a danger point appear at the same time, the map becomes very cramped.
Once you get used to it, the firm buttons are very easy to reach, work perfectly even with thicker gloves and, above all, there are no incorrect entries like on a touch display in the rain. Of course, I now have to press different buttons to navigate through the menus - but that's manageable with a little getting used to.
Uphill or downhill? Think about it!
The recording of tracks in Enduro mode does not switch automatically between uphill and downhill. You have to switch the mode before the ascent, or the Garmin sat nav makes no difference and simply calculates the altitude metres.
However, if you want a clear overview of the times or the metres of depth covered, for example, you have to think about the transition. This is somewhat difficult in the heat of the chase over natural trails, where no bike park lift provides the necessary break.
However, I would like to emphasise the price of 400 euros, which is very reasonable compared to the large Garmin Edge models - and that with almost the same or even more functions if you want to use the new activity profiles.
This makes the "small" Edge from Garmin a good alternative not only for gravity fans. The battery life was also in a good range after the software update: still approx. 60 % battery power after a good 5 hours of activity in Enduro mode.
Connectivity with the chest strap (Garmin) and e-bike (Trek) worked smoothly as usual.
