7.6 Wheels and tires
The wheels are extremely stressed parts of the bike that make contact
with the road, provide the propulsion and buffer the road bumps. Due
to this heavy use, they should be regularly monitored and reviewed.
All wheels are manufactured with great care and precision.
They consist of the hub (ball bearing hub in the front wheel and electric
motor in the rear), the high-quality 2 mm stainless steel spokes and
rims.
In unlikely cases of radial and axial offset or broken spokes, the wheels
should be repaired or re-centered immediately.
This should be done by an authorized dealer.
For removal and installation of the wheels due to a puncture or in the
case of transportation you take the following steps:
Disassembly of the rear wheel
■
Shift the chain to the smallest sprocket on the free wheel
■
Turn off the electric drive system and disconnect the motor connector
below the right chain stay of the frame
■
Remove the screw on the mounting bracket (cable guide) below on
the chain stay(Image 44a+b)
■
Loosen the axle nut of the motor with a 19 mm wrench
■
Remove the screw of the locking washer (Image 45) on the left side of
the axle (drive direction) and remove the screw and washer
■
Now pull the wheel out of the dropout, thereby pivot the rear
derailleur backwards
