Installation Of Pendix; Safety At Work; Requirements For Installation - Pendix Montageanleitung

5. Installation of Pendix

5.1 Safety at work

Wear suitable work clothing such as gloves and solid
shoes when mounting the Pendix. Attach the bicycle
frame firmly to a suitable frame holder.
Always use suitable tools and equipment meeting
good quality standards.
If you are not sure about how to put the abo-
ve safety notes into practice, information on
the subject of safety at work is easily obtain-
able. Consult for example relevant locally
applicable legal requirements, safety measu-
re guidelines and / or regulations, for examp-
le in the internet.
For your safety, the battery must not be
connected when installing the motor. Do not
place the battery in its holder until you have
finished assembly / mounting work.
Never use a high-pressure cleaner to clean
your Pendix motor components. Warning: by
doing so, water can intrude into the system
and destroy it.

5.2 Requirements for installation

Before installing the Pendix system, you have to
check if the bicycle frame fulfills the requirements.
If your bicycle frame does not meet the de-
scribed prerequirements, we cannot assume
any guarantee.
Frame material
Pendix can be attached to all metal frames. If you
wish to mount a Pendix system to a frame consisting
of other materials such as carbon, wood, etc. plea-
se consult our Pendix Service Department before
installation.
BSA bottom bracket housing with following
dimensions:
diameter: 33.7 mm – 34.0 mm,
width: 68 mm or 73 mm +- 0.2 mm
thread: BSA 1.375" x 24 TPI (FG34)
Check the diameter of the bottom bracket housing:
The interior diameter must measure between 33.7
mm and 34 mm.
Check width and condition:
The width of the bottom bracket housing must be eit-
her 68 mm or 73 mm. In each case with a tolerance of
+/- 0.2 mm.
The bottom bracket housing should be smooth and
free of paint or coating residues. The threads must be
aligned and free of dirt.
Maximum rear structure width:
Required measurements: 105 mm width at a distance
of 90 mm to the center of the bottom bracket shaft.
Caution: in the case of fully suspended rear structu-
res, keep in mind that the rear structure does not turn
centrally around the bottom bracket as in most cases!
Testing the crank
Check to see that the available chain wheels fit round
the crank.
The following illustration shows the right-hand crank. It
also gives the connection dimensions for chain wheel
fitting. All chain wheels with a 104 mm connection
diameter can be used, single and multiple sprocket
wheels are compatible. You can install all commerci-
ally available pedals with 9 / 16" x 20 RH (FG 14.3)
right hand thread.
Due to the combination of the supplied bottom bracket
and the crank, a chain line (catenary) of 49 mm is ob-
tained, as determined between the longitudinal central
plane of the frame and that of the central chain wheel.
Checking the position of the battery holder
The holder for the battery should be attached either
to the down tube or the seat tube. Already available
attachment holes for a standard drinking bottle holder
may be used for attachment of the battery holder. If
it is necessary to make new attachment holes, these
must have an M5 thread in order to attach the holder
using the screws supplied with the Pendix accesso-
ries. In the case of new attachment holes, we recom-
mend using steel tightening nuts.
