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.

6.7Lightingsystem

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.

6.8Lock

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.

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.
