Installation of the various Pedelec Sensor types
There are three types of sensor kit that can be used, two that fit on the right side of the bike between the
chain-ring and frame, and the other left-side sensor which slots into the end of the bottom bracket.
The standard right-side pedelec kit consists of two parts, these are the sensor itself and the PAS disc. You
will need to remove the bottom bracket and then slide the sensor ring into place as shown below. With
the sensor in position, you can refit the bottom bracket. With the bottom bracket re-installed, slide the
PAS disc over the spindle so that it is as close as possible to the sensor, without actually touching it.
You need to ensure that the disc is the correct way around on the spindle, otherwise you will find that the
motor kicks in when you pedal backwards! The disc should be fitted such that the arrows on the disc are
on the left side.
The supplied sensor/disc may differ slightly from the one shown above, but the installation procedure will
be the same.
A variation of this same arrangement is shown below, it still uses a PAS disc much like the above, but uses
a sensor which is mounted onto the downtube instead.
