7.7 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 (dynamo hub in the front wheel and
electric motor in the rear), the high-quality stainless steel spo-
kes and rims. (2 mm spoke in front wheel and 2.3 mm spoke
in rear wheel) 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
■
Loosen the motor connectors clamp on the inside of the
■
left chain stay, using a Torx T25 key. Slide the clamp aside
and disconnect the motor connector (Images 48a + b)
Loosen the axle nuts, using a 19mm hex wrench
■
Loosen the screw of the locking washer on the left side
■
of the axle (drive direction) and remove the screw and
washer (Image 49)
Now pull the wheel out of the dropout, thereby pivot the
■
rear derailleur backwards
Ensure the disc-brake with the enclosed transport lock
■
between the brake pads (Image 50)
This prevents the accidental compression of the pads by
■
the unintended application of the lever
The assembly is done in reverse order
■
During assembly please carefully place the disc between
■
the brake pads, please remove the transport lock in
advance
Caution: Take care to tighten the axle nuts to the
proper torque (40 Nm)!
