Spoking in the motor

2.1 Requirements

The fork of the bicycle should preferably be made from steel. The fork must not be distorted.
Aluminium forks
This also applies for suspension forks in particular.
Required fitting widths:
Only standard wheel rims with 36 spoke holes can be used. We recommend hollow section rims that are
punched and eyeletted.

2.2 Spoke lengths

The spoke lengths are identical for the rear wheel and front wheel motor.
36 spokes in the following length are required:
Wheel rim
diameter
28"
26"
20"
The specified spoke lengths are guide values for standard wheel rims. Different lengths may be required
for special wheel rim types.
The motors are not spoked symmetrically to the centre of the wheel rim. This means that the spokes
have to be pulled in and tensioned to different extents depending on the side.
In the front wheel, the motor strays to the right from the centre of the wheel rim. In the rear wheel, the
motor strays to the left.
