18.1 Checking the wheels
The pedelec is connected to the ground by the
wheels. The wheels are subject to a great deal
of strain through the uneven characteristics of
the ground and the weight of the rider.
Thorough checks and centring work on the
wheels is undertaken before they are shipped.
However, during the first few kilometres of rid-
ing, the spokes bed in.
• After the first 100 kilometres, the wheels
have to be checked by a specialist and cen-
tred again if required.
• The tension of the spokes has to be checked
at regular intervals. Loose or damaged
spokes have to be replaced or centred by a
specialist retailer.
The wheels can be fixed in the frame and fork
in different ways. Commonly, the wheel is at-
tached with an axle nut or a quick release. In
addition, there are also various thru axle con-
nections which are screwed in or fixed with
various quick release systems. If a thru axle
is fitted on your pedelec, you can get more
information in the enclosed manufacturer op-
erating manual or on the respective manufac-
turer’s website on the Internet.
18.3 Checking the rims
The rims will wear more quickly if the wheels
are fitted with rim brakes.
18.2 Checking the hubs
You can check the hub bearings as follows:
• Lift the wheels up from the ground by first
lifting the pedelec at the front then at the
rear. Push each wheel to start them turn-
ing.
• The wheel should continue to turn and then
slow evenly. If the wheel suddenly stops, the
bearing is defective. One exception is front
wheels with a hub dynamo.
• The hub bearing should not exhibit play.
Pull the wheels in the front and rear fork
lightly to the sides to check if they are loose.
• If the wheels can be slightly moved in their
bearings or are difficult to turn, the hub
bearings have to be set up by a specialist
retailer.
The stability of the rims will be
reduced if they are well worn.
This increases the vulnerability
to damage. A bent, cracked or broken
rim can cause serious accidents. Do not
continue to use your pedelec if you notice
damage on one of the rims. Please allow
a specialist retailer to check the rims.
All screws have to be tightened
with the correct torque. If the
torque is not correct, the screws
could break or loosen other parts (see
chapter 33.3 “Toques for screwed con-
nections”).
