Flyer Uproc 4 4.10 in test
The new Panasonic motor with two-speed gearbox is the hallmark of the Flyer Uproc series. Together with the 10-speed cassette, the gearbox ensures a wide gear spread.

In sports use, however, front shifting is quite sluggish. The semi-integrated battery can be conveniently removed from the side, but at 432 Wh it doesn't provide much range. On the other hand, the display and control unit offer a wealth of information and functions. The bike gave no cause for criticism during the ride test. It climbs well, and thanks to the super-short chainstays, it is easy to manoeuvre through tight trails. On the descents, you benefit from the good suspension. However, we would have liked tyres with a coarser profile.


ConclusionFull suspension travel, good geometry, solid chassis - a genuine all-mountain bike, unfortunately with little reach.
