1 About these instructions
Read these operating instructions before
commissioning the bicycle to ensure you use all the
functions correctly and safely. The operating
instructions are not a substitute for personal
instruction by the supplying specialist dealer. The
operating instructions are a component part of the
bicycle. Therefore, if it is re-sold at a later time, they
must be handed over to the subsequent owner.
These operating instructions are mainly intended for
the rider and operator of the bicycle, who tend to be
non-professionals.
Staff at all specialist dealers have specialist training
and qualifications, and are therefore capable of
identifying risks and preventing hazards which may
arise during maintenance, servicing and repairs on the
bicycle. Information for specialist staff does not require
non-professionals to take any action.
1.1 Manufacturer
The manufacturer of the bicycle is:
ZEG Zweirad-Einkaufs-Genossenschaft eG
Longericher Straße 2
50739 Köln, Germany
Tel.: [phone]
Fax: [phone]
E-mail: [email protected]

Text passages which are expressly intended for
specialist staff (e.g. bicycle mechanics) are clearly
marked with a tool symbol.
