9�6 Checking the front wheel and rear wheel
1. Hold the balance bike firmly by the front fork or frame.
2. Try to move the front or rear wheel sideways. Check whether the wheel nuts move
as you do so.
x If the wheel nuts move, tighten them (see the “Basics / Notes on torques” chapter).
3. Lift the balance bike and turn the front or rear wheel. Check whether the front or
rear wheel swings sideways or outwards.
x If the front or rear wheel swings sideways or outwards, do not use the balance
bike and have the wheel checked by your dealer.
9�7 Checking the rims and spokes
1. Check the front and rear rims for cracks, deformation or discolouration (visual
inspection).
x If a rim is cracked, deformed or discoloured, do not allow your child to ride the
balance bike.
2. Squeeze the spokes together gently with your thumb and fingers, checking
whether the tension is the same for all spokes.
x If the tension varies or spokes are loose, have the spokes tensioned by your
dealer.
Alternatively, you can run a wooden or plastic rod across the spokes and
listen for differences in sound.
9�8 Checking the tyres
1. Check whether the tyre pressure is correct (see the “Basic adjustments / Checking
and adjusting the tyre pressure” chapter).
2. Check the tyres for cracks and damage from foreign bodies.
3. Check whether you can clearly feel the tyre tread.
x If a tyre is cracked or damaged, or the tread depth is too low, have the tyre
replaced by your dealer and do not let your child ride the balance bike.
4. Check whether the valves are firmly in place and hand-tighten the lower knurled
nut if necessary by turning it clockwise.
5. Check whether the valves have a protective cap.
x If the protective cap is missing, replace it.
