When you think of Flyer, the first thing that comes to mind is certainly not a fat e-mountain bike, but that may soon change. The Uproc7 is an imposing sight: it rolls on 27.5-inch Plus tires, has 160 millimetres of suspension travel at the front and rear, is accelerated by a Panasonic motor (and a little muscle power) and stopped by Magura brakes. This has piqued our interest, so let's take a closer look.

1. the cockpit

The 3.5-inch color display in the middle of the handlebars is clearly visible. You always have all the important data in view, and thanks to the backlighting, it is easy to read even in direct sunlight. It is controlled via the large remote switch on the left-hand side of the handlebar, which has pushbuttons, buttons and a small joystick. The whole thing takes some getting used to, but is then very intuitive. The button for the optional Vario support and the SLX gears are located on the right-hand side of the handlebars.

2. the frame

The hydroformed aluminum frame is beautifully finished. The battery is integrated into the down tube and is therefore not very noticeable. At the rear is a four-bar linkage system developed by Flyer with a Monarch MT shock from Rock Shox. The suspension fork also comes from Rock Shox, the choice fell on the YARI RC model.

3. the drive

The mid-motor comes from Panasonic and has two gears, which increases the range enormously, which is particularly important for mountain bikers. Four support levels can be selected: Automatic, Eco, Standard and High. The automatic mode is special: depending on the terrain, cadence and speed, the motor automatically shifts the 2-speed gearbox and the three support levels of the motor. The necessary "juice" for this is provided by a battery with 432 watt hours, 12 ampere hours and 36 volts.

4 The rolling stock

The Uproc7 rolls on Sunringlé "Duroc 40 584 Boost" complete wheels and Schwalbe "Nobby Nic Performance 70-584" tires. It is stopped with the powerful Magura MT5 four-piston brakes.

5. enough looking, now it's time to ride!

We press the "on switch", the display starts up and we're ready to go. We select the assistance level (standard) with the thumb on our left hand and start pedaling. After three turns of the cranks we already had a big grin on our faces, the acceleration is simply phenomenal. From 25 km/h, the fun is over for the time being, from then on only muscle power counts, but even with this, the bike is still easy to ride. The riding position can confidently be described as neutral or relaxed; sit on it and feel comfortable is the motto. On the climbs, no matter how steep, the e-bike plays all its trump cards, and even the roughest ramps lose their terror. The motor noise is clearly audible under full load, but is not annoying. The assistance kicks in remarkably smoothly, which is extremely important, especially on steep uphill serpentines. Nevertheless, there is still room for improvement here, but we are complaining at a high level.

The 27.5 Plus tires are perfect for an e-bike. Thanks to the motor, the disadvantage of higher rolling resistance at low tire pressure - we rode the 24-kilogram bike at just 1.1 bar - is not really relevant. The traction, on the other hand, is enormous.

We switch the engine to "Eco" and race down an initially steep gravel road. Braking on a bend is almost boring, the bike behaves so smoothly thanks to the low center of gravity, the fat tires and the Magura four-piston brakes, which incidentally showed no weaknesses. Even the root passages posed no problems for the bike. We only wished for more defined handling and better feedback in sloping sections on firm ground.

Due to the relatively high overall weight, playing with the bike on flowing trails takes a back seat; small jumps and similar maneuvers are certainly feasible, but require some effort from the rider. Nevertheless, we were pleasantly surprised at how little you notice the weight, and sometimes you even forget that you're on an e-mountainbike.

Conclusion

The Uproc7 impressed us in several ways. It shines with clean workmanship, a coherent overall concept and a great design. The handling is neutral and you always have enough reserves thanks to the tires and ample suspension travel. The motor develops its power very smoothly and still gets you up the steepest climbs with ease. The relatively large display and remote switch is not for fans of clean cockpits.
