Uproc4 | FLYER E-Bikes

The E-Fully for explorers.

The Uproc4 is the ideal E-Fully for E-mountainbikers who like to ride on different terrains and are looking for a particularly versatile all-mountain fully. With its 140 mm suspension travel and 27,5"+ tyres with maximum grip, it is almost as robust as our Uproc7 flagship on challenging terrain, and slightly more agile on moderate trails. Driven by the Panasonic GX Ultimate motor, which weighs just 2,9 kg, the Uproc4 provides powerful and harmonious assistance – even on the steepest inclines. The cleverly integrated high-capacity 630 Wh battery provides a great deal of energy for long tours covering significant differences in altitude. There can be no doubt that the Uproc4 is your ideal companion for discovery tours.

Price: from EUR 4'399.00

Panasonic GX Ultimate

Weighing just 2,9 kg, the new Panasonic GX Ultimate is one of the lightest in its class, yet provides record levels of assistance with 90 Nm torque and 600 watts of peak performance. The new drive unit is impressive with its constant power output across an extremely wide pedal cadence range, which means the best level of assistance is also guaranteed at a low pedal frequency.

SIB-630 battery

The large 630 Wh battery provides plenty of energy for long tours that cover great differences in altitude.

SIB integration

Smart battery integration makes it easy to change the battery and guarantees that the battery remains securely attached even on bumpy terrain. The L-shaped down tube construction maximises frame rigidity and guarantees precise and confident handling.

FLYER display and remote

The control elements developed by FLYER are clearly laid out, simple to operate and perfectly ergonomic - quality you can touch and experience. The 3,5 -inch FLYER D1 display with comprehensive additional functions is available as an option. Find out more about FLYER Intelligent Technology (FIT).

4-link suspension - 140 mm suspension travel

The active chassis with four-link suspension and e-bike-specific calibration offers 140 mm suspension travel for the highest level of comfort and riding safety on challenging trails.

Modern frame geometry

The flat steering angle and optimised weight distribution provide a particularly high level of riding stability, while the central seating position guarantees the best climbing capabilities. The low top tube increases freedom of movement and safety on any terrain.

Aluminium motor cover

Beautifully formed and integrated into the frame, the aluminium motor cover protects the drive and ensures optimum cooling.

Integrated speed sensor

Integrated into the dropout, the speed sensor is barely visible and ideally protected.
