Children's road bike
Adjusting the brakes:
The bicycle has two calliper brakes. The left
brake lever operates the brake on the front
wheel, the right brake lever operates the brake
on the rear wheel. Depending on the model,
the bicycle may also have a back pedal brake
for the rear wheel.
Figure 5: Centre the brake arms (1) by turn-
ing the adjusting screw. The gap between the
brake pad <-> rim should be identical on both
right and left and the contact between brake
pad/rim should be applied simultaneously on
both sides when you brake. You will need a
cross-headed screwdriver. By turning the
screw in, you move the appropriate brake arm
away from the rim, turning the screw out
moves the screw towards the rim.
It is important that the brake levers are actuat-
ed several times so that the tension of the
brake arms is evenly distributed to both sides
and the settings take effect.
Figure 6: The handle distance (distance of
brake lever to handlebar) can be adjusted indi-
vidually using an Allen key on the brake han-
dle. Please remember that braking must taken
effect before the brake lever reaches the han-
dlebar!
Figure 7: The tension can be set on the brake
handle using the knurled screw.
The brake is set correctly if the brake pads are
all approximately 1.5 mm from the rims.
Replacing the brake pads
Figure 8: Undo the fastening nut of the brake
pad using an Allen key sized 5 mm (1) and
replace the brake pads.
This means that the brake pads should rest
1 mm below the top edge of the rim (2). If
these settings are not correct, loosen the fas-
tening nut of the brake pad (1) with a 5 mm
Allen key and align as described above. To do
so, pull the brake lever and re-tighten the
fastening nut (5-8 Nm).
The tension is to be set so that the brake pads
are all approximately 1.5 mm from the rims. If
subsequent adjustment is necessary, undo the
tensioning screw (3) and adjust the tension
(tighten the tensioning screw back up using
6-8 Nm!) or carry out the step described in
Figure 7.
Setting the chain tension
(models with gear hub)
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 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 derailleur 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.
