Use of other displays

The display acts as an immobilizer and,
therefore, you cannot install of fully use
every display on your e-bike.
A unique code has been saved on your
display that matches the related e-bike. If you
want to switch on the assistance or lights, the
system will check whether the display
and the bike form a unit. If this is not
the case, error message E14 will be
displayed and the assistance and lights
cannot be switched on. If you have two
e-bikes with the same display type, you
can register both displays on both bikes.
Your certified e-bike dealer can perform
this for you. Both displays will then work
on both bikes.

Speed sensor

The speed sensor only works on e-bikes with a middle motor.
Your e-bike's system needs information
to function properly. The speed
information is obtained by the rear wheel
sensor (A) (behind the chain casing)
and a magnet (B) in the wheel.
Sometimes the magnet becomes
dislodged, for instance when cleaning
the e-bike or when loading/unloading
the e-bike on the bicycle carrier. If the
magnet becomes dislodged, then the
speed can no longer be measured.
Your display will indicate 'Check speed
sensor'. In this case you can still cycle
