7 Hub shifting systems
7.1 Basics
Usually all modern cycles have a gear shifting
system installed; this depends on the cycle
model. Exceptions include children’s bikes,
which may only have one gear depending on
the model.
The gear shifting system on a cycle consists
of a variable gear unit and the corresponding
controls. As a result, the power provided by
the rider is adapted to suit the riding speed
and route conditions.
Adjustments to the gear shifting system
require expertise.
x If you lack the necessary expertise and
the tools required to adjust the hub
shifting system, contact your dealer.
7.1.1 Automatic shifting system (Automatix)
This chapter applies to models with an optional “Automatix” gear shifting
system (see the specifications data sheet provided by the dealer).
The rear wheel hub is equipped with an automatic shifting system. The gear shifting
system automatically shifts up to 2nd gear or down to 1st gear depending on your speed.
Automatix gear shifting systems are available both with a freewheel and with a coaster
brake. Check the data sheet completed by your dealer to find out which variant is
installed.
x If the gear shifting system does not shift gear automatically, or produces noises,
have the system checked by your dealer.
