6.6 Tyres and inner tubes

6.6.1 Tyres
Lafree Twist's tyres are general-purpose in
design, made for improved (paved) road
surfaces. They are not designed for
unimproved roads or trails where dirt, loose
rocks, or other loose debris is present. Your
dealer can help you select new tyres once
they warrant replacement.
The size and pressure rating are marked on
the side wall of the tyre (see fig. 24). The part
of this information which is most important to
you is tyre pressure.
The best way to inflate a bicycle tyre to the
correct pressure is with a bicycle pump. Your
dealer can help you select an appropriate
pump.
6.6.2 Tyre air valves
Lafree Twist tyres are equipped with "French
valves". To inflate a French valve tube,
remove the valve cap, loosen the little centre
nut a few turns. By pushing the centre nut
downwards you can remove air from the
tube. Make sure the pump matches the valve
type. Contact your dealer if necessary.

6.7 Lighting system

The electricity for the lighting equipment (front
and rear light) is provided by the dynamo,
attached to the left side of the front fork.
If there is no need for the lighting to work, the
dynamo can be in the "OFF" position, which
means that the pulley on the top of the
dynamo doesn't contact the tyre of the front
wheel. If the lights have to work, the pulley of
the dynamo has to be driven by the tyre of
the front wheel.
To switch the dynamo (and the lights) "ON",
push the dynamo downward. A spring will
push the pulley of the dynamo against the
side wall of the tyre. When the front wheel
rotates, the dynamo will generate electricity
and the lights will burn.
If the dynamo is pulled sideways (away from
the tyre), it will be pushed upward by a spring
and remain in the "OFF" position.
6.8 Lock
Lafree Twist is equipped with a bicycle lock.
How to lock the bike.
First, turn the key clockwise as far as
possible (just a little bit).
Then, while keeping the key in this position,
push the big knob on the opposite side all the
way downward. If the knob is not pushed far
enough, it will come back into its starting
position automatically. Now, the bike is locked
and the key can be pulled out of the lock.
Note: make sure that the shackle of the lock
can pass between 2 spokes. If a spoke is in
the way, just rotate the rear wheel a bit.
How to unlock the bike.
FIG. 24
Hold the knob of the lock with one hand and
with your other hand insert the key into the
keyhole of the lock. Now, turn the key a little
bit clockwise. A strong spring will release the
lock and the knob wants to jump back
upward. Guide the knob back into the upper
position carefully.
Note that the bicycle lock prevents the rear
wheel from turning, making it less interesting
for thieves to steal the Lafree Twist. However,
the bike can still be carried away. It is
recommended to combine the bicycle lock
with a special cable or chain that fixes the
bike to a tree, lamppost or bicycle rack.
Don't forget to turn the key of the battery lock
anti-clockwise to the "LOCK" position and to
pull out the key.
