10 Frame
The form of the frame depends on the bike type and func-
tion. Frames are manufactured from different materials
– steel or aluminium alloys or carbon (carbon fibre), for
example.
The frame number of the bike is stamped on the seat
tube, the dropout or the bottom bracket housing.
It may also be found on the motor suspension in Pe-
delecs. The bike can be identified by the frame num-
ber if it is stolen. To identify the bike properly, it is
important to note down the whole number in the right
order.
Never ride your bike if the frame is warped or
cracked. On no account should you attempt to repair
damaged parts. This can lead to accidents. Replace
defective parts before you ride the bike again.
After an accident or crash, have your bike checked by
a professional bike workshop before riding it again. If
defects on the frame or components go unnoticed this
can lead to accidents.
If your bike does not roll forwards easily in a straight
line, this could mean that the frame is warped. In this
case, have the steering stability checked by a profes-
sional bike workshop.
