The Swiss brand FLYER is the only manufacturer that relies on the lightweight and powerful Panasonic GX0 motor. But there is much more to the FLYER Uproc7 4.10 than a powerful motor!

FLYER Uproc7 4.10 | Panasonic GX0/630 Wh | 160/160 mm (f/r) | 24.32 kg | € 4,499

Traction and comfort are the keywords regarding the 24.32 kg FLYER Uproc7 4.10. To achieve that the Swiss brand relies on 27.5″ x 2.6″ Schwalbe Magic Mary tires and 160 mm travel RockShox suspension. The € 4,499 bike comes with their D0 display and the powerful Panasonic GX0 motor, fed by a 630 Wh semi-integrated battery. The Uproc7 4.10 is available from FLYER with either their D0 or D1 display. The more compact D0 display provides all the basic information. The huge D1 display we had on our test bike costs an additional € 300; it’s capable of providing you with a host of fitness data as well as navigation via a Komoot interface. However, both displays are only partially suitable for aggressive trail use. If you want to use the onboard display to navigate, you are unlikely to have much joy with the D1: the Komoot interface only shows arrows, but not the route – not accurate enough for trail use! The exposed position of the display and remote also means they’ll quickly get scratched or broken if you crash. For the drivetrain, FLYER relies on an 11-speed Shimano XT rear derailleur paired with an SLX shifter, unfortunately. The SLX shifter is much spongier and less defined than the XT version.

You wouldn’t drive off-road with an S-Class. The FLYER feels most comfortable on wide forest roads and on long relaxed rides.

Not enough
Two pistons aren’t enough. The rear brake just isn’t powerful enough, especially in combination with the 180 mm brake rotor.
Palanquin
The rear suspension of the FLYER is designed for comfort. As with a palanquin, this is a shaky affair: it works on slow rides, but as soon as the terrain becomes more demanding it regularly bottoms out.
Powerhouse
Thanks to its 90 Nm torque, the Panasonic GX0 isn’t fazed by steep climbs.
Not quiet
The SIB battery provides plenty of power with 630 Wh. Unfortunately, it also rattles in the frame mount.
Grip
The wide Magic Mary tire on the rear not only provides massive traction and stability on the descents, but it also makes technical climbs easier.
Soft
The soft chainstay protector really covers all areas. You never hear the chain – thumbs up!

The FLYER Uproc7 4.10 in review

The Panasonic motor in the FLYER turns the Uproc7 4.10 into a true mountain goat. Thanks to the 90 Nm torque output and the smart automatic mode, the motor is very sensitive yet sufficiently powerful, although it is relatively loud on the Uproc7. In combination with the super grippy Schwalbe Magic Mary tire on the rear, steep, technical climbs are no problem. In a direct comparison to other motors, the GX 0 is “only” capable of multiplying your leg-power by three. So, letting the motor pull you up the mountain is not an option. Instead, the Panasonic scores with its natural ride feel. The FLYER also feels really comfortable in less extreme terrain like gravel service roads. The balanced pedalling position and the tuning of the suspension mean that you’ll remain comfortable on long rides, which is unfortunately disrupted by the rattling of the 630 Wh battery. Correctly setting and re-adjusting the battery mount is essential on the Uproc7.

Tuning tip: increase the progression of suspension with volume spacers | larger brake rotor/more powerful brake on the rear

On leisurely descents, the FLYER Uproc7 is easy to manoeuvre along the trail. It offers a lot of traction and holds its line well, providing sufficient amounts of confidence. Thanks to the balanced weight distribution, even low-speed corners are easy to roll through. Let go of the undersized two-piston MAGURA MT Trail brake on the rear calliper however, and the Uproc7 quickly reaches its limits. The rather linear suspension rushes through its travel, bottoming out even with medium-sized obstacles. Actively changing direction or jumping the bike requires a lot of physical effort, since the suspension swallows the rider’s input, designed to prioritise comfort over agility.

Unique feature: a lot of you won’t have heard much about the Panasonic GX0 motor before. It responds sensitively and feels very natural, fitting in perfectly with the character of the FLYER Uproc7.

Conclusion

With the FLYER Uproc7 4.10, you can climb “almost” everything. The traction-generating suspension,balanced pedalling position and the powerful motor cut a good figure on climbs and on long rides. For aggressive riders, however, the suspension and geometry of the Uproc7 4.10 are too spongy and sluggish. You’ll only really have fun if you aim to leisurely cruise along the trails.
