Adjusting the gear indexing for the
DualDrive hub gear
Turn the left twist grip for the hub gear to the
standard mode "2".
At the right side at the rear axle there is the
click box for the hub gear. In the transparent
window you see a yellow indicator.Adjust this
indicator in line with the mark at the click box
by turning the adjustment screw where the ca-
ble goes into the box.
All moving parts of the gear system are affec-
ted by wear. Cleaning and lubricating these
parts frequently can prolong the life of these
parts, however they will have to be replaced
once worn out.
The cables have to be checked, cleaned and
serviced regularly. Expect more wear and cor-
rosion when the bike is often parked outside
in bad weather conditions.

Gear system
Please read the manual of the gear system ma-
nufacturer carefully before working on the
gear system.
Your dealer will adjust your derailleur gearing
system carefully before handing over the trike.
But during the first 300 kilometres (186 miles)
of riding the cables can stretch, making the
gear indexing imprecise.The chain then climbs
only hesitantly onto the next sprocket.
Adjusting the gear indexing for the derail-
leur gear
Adjust the barrel adjuster where the gear ca-
ble goes into right twist grip or the derailleur.
Do it in small steps of half a turn.
Check after each adjustment whether the
chain moves smoothly up to the next larger
sprocket.To do this, either turn the cranks by
hand or ride the bike.
When the chain climbs up easily, you need to
check that it still goes down easily onto the
smallest sprocket. If necessary turn the barrel
adjuster a little more and then try shifting ge-
ars again.
Gear system
Danger! If the chain shifts over the smallest
or the biggest sprocket you have to readjust
the end-limit adjusters of the rear derailleur.
Incorrect adjustment can lead to the chain
coming off, getting stuck or damaging the
spokes, which may result in serious falls.The
adjustment of the end-limit adjusters is a job
for the professional cycle mechanic.
Danger! If the bike falls over, the derailleur
or its mounting can be bent so that the mo-
vement range of the derailleur changes.
Check the movement range and have it re-
adjusted by your bicycle mechanic, if neces-
sary.
Caution! Damaged cables that show for
example single wires have to be changed
immediately. Otherwise they may damage
your gear system.Take care that the ends
of the cables are protected with fitting
caps.
