The gears
The gears
(a-c)
of your CENTURION pedelec serve
to adjust the gear ratio to the terrain you are riding
on and the desired speed. Modern CENTURION
pedelecs can have up to 11 gears.
In the case of
derailleur gears
a low gear allows you
to climb steep hills with moderate pedaling force.
You must, however, pedal at a faster pace or higher
frequency. Downhill you switch to a high gear. Every
turn of the pedals takes you many meters forward at
correspondingly high speed.
Continue pedaling during gear shifting, however, at
clearly reduced pedaling force, i.e. you should pedal
slowly and without force.
In the case of
multi-speed hubs
and
gearbox shift
systems
“1” stands for the first, lowest gear. The
gears are shifted through one after the other, if pos-
sible without turning the pedals, at least, however, at
reduced pedal pressure. The highest number stands
for the highest gear.
NuVinci N360 gear hubs
(d)
are designed to allow
stepless shifting by means of a twist grip within their
range of gear ratio. With the NuVinci hub the force
transmission is ensured by balls instead of toothed
wheels. Make it a rule to shift only while pedaling at
reduced force.
With NuVinci the actual gear ratio is indicated to the
cyclist on the display. If the cyclist climbs uphill, the
gear ratio is low, on level ground the gear ratio is high.
The
H-Sync
gear system integrates the
NuVinci
Harmony
®
gear hubs into the Intuvia system of its
Bosch drive. With H-Sync you can predefine your
preferred cadence (between 30 and 80 turns per
minute). The drive readjusts automatically – both
uphill as well as downhill. This allows you to always
maintain your preset cadence.
For more information see the chapter “The gears”
in your comprehensive original CENTURION user
manual as well as in the instructions of the compo-
nent manufacturers on the enclosed CENTURION
CD-ROM.

Before you set off for the first time
practice shifting gears in a place free
of traffic until you are familiar with the
functioning of the levers or twist grips of your
CENTURION pedelec.
A
Always make sure changing gears
makes as little noise as possible and is
absolutely jerk free.
I
Read in any case the chapter “The
gears” in your comprehensive original
CENTURION user manual as well as in
the instructions of the gear manufacturer on the
enclosed CENTURION CD-ROM before you start
to readjust or to service the gears or before doing
any work whatsoever.
