Shift sensor

The shift sensor* is only mounted on e-bikes with a central motor.
The shift sensor (A) allows for smooth
gear shifting. This provides more comfort
and less wear to components, like the
chain.
The sensor, which is assembled around
the gear cable, receives the shift
information. On most models, the sensor
is positioned on the rear fork next to
the rear wheel. See appended image.

This, however, may vary per bike model.
The words 'ION Smart Shift Sensor' are
stated on the sensor.
If there is a defect in the shift sensor, message 'E59 Shift sensor disabled'
will appear on your display. This message will only be displayed once until
the system has been switched off and on. If this error message appears, you
can still cycle with assistance, but the gears won't shift so smoothly.
*Optional.
