tensioning screw (3) and adjust the tension
(tighten the tensioning screw back up using 68
Nm!) or carry out the step described in Figure
11.
Setting the chain tension (models with gear
hub) The chain should have a vertical play of
approximately 1.5 cm. The setting of the chain
tension is carried out as follows: Figure 9: Undo
both wheel nuts of the rear wheel. Adjust the
chain tension by sliding the rear wheel at the
dropout. Then tighten the wheel nuts back up
again (torque 20 Nm). For models with derail
leur gears, the chain tension is regulated via
the gears.
Attention should be paid to ensure that the
correct chain length is selected when replacing
the chain.
Figure 13: Please note that one pedal is
equipped with a righthanded thread (for the
righthanded driving direction) and the other
pedal with a lefthanded thread (for the
lefthanded direction). The pedals are labelled
accordingly on the front face of the threaded
axle with an "R" and an "L".
Screw the pedals with the aid of a 15 mm span
ner to the cranks (20 Nm) – to do so, turn the
Allen key on both sides in the direction of the
front wheel.
Setting the seating position
Figure 14: Setting the height of the saddle:
The saddle can be pulled out after releasing
the saddle clamp with the aid of a 5mm Allen
key. Set the saddle so that at least the toes,
preferably the ball of the foot, reach the ground
in order to ensure balance can be achieved
when at a standstill.
Please observe the following principles:
Minimum height of the saddle as follows:
Z2 / ZL 12: 45 cm
Z6 / ZL 16: 49 cm
Z8 / ZL18: 53 cm
Maximum height of the saddle:
The minimum insertion depth of the saddle
post is 65 mm. There is an appropriate marking
on the saddle post (see Figure 8).
Then retighten the saddle clamp (torque
58 Nm).
Setting the height of the handlebar: Adjust the
seating position so that the child is seated up
right and a good overview is ensured. The han
dlebar, hand brake lever and bell must be easy
for the child to reach.
The torque for the clamping of the stem in the
fork stem: 15 Nm.
The torque for the clamping of the handlebar in
the stem: 12 Nm.
Setting the chain tension
The chain should have a vertical play of ap
proximately 1.5 cm. The setting of the chain
tension is carried out as follows:
Figure 15: Undo both wheel nuts of the rear
wheel
Figure 16: Adjust the chain tension by sliding
the rear wheel at the dropout. Then tighten the
wheel nuts again (torque 10 Nm)
