Handling instructions
Danger! There must be a bush-
ing (a slotted tube of plastic with edges to
the front and the clamping slot) in the main
frame’s front boom hole that is glued in
the frame. This bush ensures safe clamping
of the front boom and protects the paint.
It is important to take care that this bush is
always visible at the front end of the main
frame. The lower slot has to be aligned in
coincidence with the slot in the main
frame. If this bush is missing or moved to
the back of the tube while inserting the
front boom, safe clamping is no longer
guaranteed, even if it seems to be the case
at first glance. If the front boom is not
clamped properly it may turn and lead to a
fall. A missing or misaligned bush will lead
to frame damage.
Danger! If the bolts are tight-
ened too much or bent, the screw or the
frame can break! If the clamping is insuffi-
cient the front boom can turn during a ride
which may cause your feet to slip from the
pedals and lead to injuries.
After moving the bottom bracket tube your
dealer has to adjust the chain length. By de-
fault the Scorpion fs 26 comes with a very
long chain so the adjustment range of the tri-
cycle can be fully used without the need to
lengthen the chain.
After the basic adjustment of the leg length
done by your dealer before handing over the
tricycle, the chain has to be shortened so that
the derailleur cage is not fully turned forward
while shifting on the largest chain ring in front
and the smallest sprocket behind. The derail-
leur must still be able to compensate a length
change of the chain of at least 4 cm (1 1/2"). In
order to choose the right chain length, please
consult the manual of the derailleur manufac-
turer.
Danger! After the chain has
been shortened it must be closed with a
special closing link or a chain riveting tool
that expands the rivet while riveting (i.e.
Rohloff- Revolver). A poorly joined chain
may break and thus lead to damage or in-
jury. Chain length adjustments or chain
changes should be done by your bicycle
mechanic.
We recommend to slightly readjusting the
front boom every 3 months so that knees in
order to provide a slightly different position
to your muscles and ankles. You might also
find a more comfortable and more efficient
riding position.
Check that there is at least a 5 cm (2") clearance be-
tween the end of the chain tube and other parts of the
drive train
A wrong adjustment may lead to pain in your
knees and inefficient pedalling. In addition we
recommend riding with a high pedalling ca-
dence, which means to pedal fast and with lit-
tle pressure. Pedalling with too much pressure
may also lead to pain in the knees.
