Product news / test: Flyer is expanding its product range with the Uproc X. The little brother of the Uproc 6 is aimed at the general public as an all-mountain E-MTB. With the Panasonic GX Ultimate motor and the new FIT 2.0 system, Flyer promises an increase in performance. Velomotion has already tested the Flyer Uproc X - you can find all the information here.
The e-bike specialist and pioneer Flyer from beautiful Switzerland has been developing bikes at a high level since the very beginning. To this day, you play at the very front – on asphalt and off-road. The latest bike from the Confederates also shows that this will not change in the future: the Uproc X 2022. Many good qualities of its bigger brother Uproc 6 flyer comes with the new Uproc X - but Flyer designed the mountain bike for the general public as an all-mountain or SUV E-MTB. The new Panasonic GX Ultimate motor delivers 95 NM of torque and draws its energy from a large 750 Wh battery. In addition to the adapted geometry, this promises enormous climbing properties.

Flyer Uproc X: The construction of the E-MTB
The carbon frame is based on the basic shape of the Flyer Uproc 6. Nevertheless, the geometry has been fundamentally revised and adapted to the all-mountain area. In detail, this means that the chain stays are a bit longer and the steering angle is a bit steeper – the latter makes the bike a bit more agile. The drive components and the controls of the electric drive are unobtrusive and practically integrated into the elegant frame. Of course, a Fidlock bottle holder should not be missing. Large industrial bearings ensure a long service life. As with most E-MTBs, the battery is located in the down tube and is removed from the side. Fyler does without a lock - the battery is released using a 6 mm Allen key. The latter is conveniently located on the rear wheel axle as an on-board tool. Compared to the Uproc 6, the battery is now firmly attached to the cover. As a result, handling when removing the battery is much more comfortable. In addition, a practical charging socket is installed above the motor.
Flyer Uproc X – the drive of the all-mountain E-MTB: Panasonic GX Ultimate in the test
Endless power: The new Panasonic GX Ultimate motor delivers up to 95 Nm of torque to the ground. This is enormous and is clearly noticeable on the trail. On our test drives, we find that we rarely need the "High" mode. Steep climbs, for which we would use the "Turbo" mode with the Bosch CX system, for example, we only ride in the "Standard" mode with the Panasonic GX Ultimate. In "High" mode, we can fly up the narrow, steep streets of our test area in Finale Ligure at almost 25 km/h - that puts a big grin on our faces! The drive of the Flyer Uproc X offers enormous performance. The noise development is kept within limits and is comparable to other systems in this performance class.
We recently dealt with the drive in great detail and measured the performance values on the test bench:

FIT 2.0 system: Testing the controls of the Flyer Uproc X
The Panasonic GX Ultimate Motor is powered by the newly developed FIT 2.0 system controlled. The latter is platform-independent and can be used for different engines. In addition to being used by Flyer, it is also used by other manufacturers in the ZEG Group. The FIT 2.0 system is well thought out and offers many interesting features: In addition to three different display sizes, there is also the option of using your own smartphone with the FIT 2.0 app as a display. You can also have the tire pressure shown on the display, for example, if you mount the appropriate valve attachments. In addition, the strength of the motor support can be set for all drive modes with just a few clicks. So you can adapt the drive individually to your own preferences and trails. The color display of the FIT 2.0 system is nice and bright and has a clear menu navigation. The tour data can be displayed on different screens. In the future there will even be the option of saving tours created via Komoot in the app on the smartphone - the navigation will then be shown on the display of the E-MTB. Handling on tour is practical and largely intuitive. The boost function is helpful on tour: If you hold down the button of the pushing aid while driving, the motor gives full power for this time. In this way, small, steep climbs can be effortlessly bridged without having to change the support mode.
The Flyer Uproc X in action: testing the all-mountain E-MTB on the trails around Finale
We were able to test the Flyer Uproc X in the 8.70 variant for two days on the trails around Finale – both uphill and downhill. With its 150 mm of travel, the bike should be able to take a beating on the descents. The strong motor in combination with 460 mm chainstays and a steep seat tube angle of 77 degrees promise good climbing abilities. Our test bike in size M has a reach of 445 mm. The seating position is comfortable and you feel right at home on the Flyer Uproc X.
Uphill properties in the test
The Flyer Uproc X goes steep! The long chainstays and the upright seat angle mean that extreme climbs can sometimes be climbed effortlessly and thus offer one or two surprises: Did I really ride up here? The bike handles well on the trail and has sufficient ground clearance. The Panasonic GX Ultimate motor delivers enormous boost in the "high" support level, as already mentioned in the text above. In steep, technical trail climbs, this is almost too much of a good thing. For example, the engine sometimes delivers too much thrust in tight uphill bends - and pushes you over the bend. Overall, we would have liked a little softer acceleration and a softer motor support slipping out when you stop pedalling. But that's whining at a high level, because Flyer already has a solution:
FIT 2.0 support mode "Auto"
The "Auto" mode of the FIT 2.0 system automatically regulates the support power of the motor according to the force that the driver puts on the pedals. In the first attempts on the plain, however, it initially seems like a complete failure. The “Auto” mode only shows its strengths on demanding climbs: the steeper the trail, the harder you pedal and the motor delivers the corresponding power. Always suitable – only a little on slow, tight corners, a lot on crisp ramps. In addition, you learn a round kick through the “Auto” mode. Once you get used to it, you don't want to do without the "Auto" mode - the other support modes are almost superfluous. In any case, after about two hours of getting used to it, we rode 90% of all uphills and downhills in this support level and found: Compared to static support modes, the "Auto" mode is a game changer.
Downhill properties in the test
The Flyer Uproc X also cuts a fine figure on descents. Rear triangle and fork work harmoniously and absorb a lot despite the "only" 150 mm travel. The progression of the rear end is balanced - you can pull off small kickers and edges with the Uproc X and the bike feels good in the air. You can really let it run downhill, even if the Uproc X doesn't quite keep up with its big brother at high speeds and rough terrain Uproc 6 can keep up. Despite the long chainstays, the E-MTB feels quite agile. These only have a negative impact on tight bends and very technical passages. The good downhill characteristics are rounded off with the Schwalbe Magic Marry and Big Betty tires and the Shimano XT four-piston brakes. Unfortunately, as with almost all manufacturers, the fun on the descent is somewhat spoiled by the adjustable seat post, which would do with more travel for the active riding style of our test editor - even if the 175 mm should be sufficient for most riders.
Conclusion on the Allmountain E-MTB Flyer Uproc X
With the Uproc X, Fyler delivers a really good all-mountain E-MTB that can definitely compete with most enduro trails. Anyone who doesn't have rough competition routes in front of the door is well served with this bike. In addition, the uphill properties of the Uproc X are really impressive. In any case, we wouldn't miss any more uphill trails with the Uproc X! But Flyer can also pay for all of this.
