6. Installation
6.1 Safety at work
Wear suitable work clothing such as gloves and solid shoes
when mounting the Pendix eDrive. 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 above
safety notes into practice, information on the
subject of safety at work is easily obtainable.
Consult for example relevant locally applicable
legal requirements, safety measure guidelines
and / or regulations, for example in the internet.
For your safety, the battery must not be con-
nected 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 eDrive motor components.
Warning: by doing so, water can intrude into the
system and destroy it.
6.2 Requirements for installation
Before installing the Pendix eDrive, 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
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.
Checking the housing width
The width of the bottom bracket housing must be either 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.
Eccentric bottom bracket
Should there be an eccentric bottom bracket in the bike,
please take care of exchanging the eccentric bushing made
of plastic by a model made of aluminum. Plastic eccentric
bushings are not approved by Pendix.
Maximum rear structure width
Caution: in the case of fully suspended rear structures,
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 commercially available chainrings with a connection di-
ameter of 104 mm can be used, single and multiple sprocket
wheels are compatible.
You can install all commercially available pedals with 9/16“ x
20 RH (FG 14.3) right hand thread.
Aer the installation of the crank, the length of the chain
line (catenary) is 49 mm, which makes it possible to use the
most common gear shiing systems. When the installation
is completed, the derailleur should be checked and if neces-
sary should be adjusted.
Please use the checklist (see section 10) and the online in-
stallation video to check the bike and the installation!
Pendix eDrive can be attached to all metal frames. If you
wish to mount a Pendix system to a frame consisting of oth-
er materials such as carbon, wood, etc. please consult our
Pendix Service Department before installation.
