3.2.4 Chain
The product has a driving mechanism with two chains. Make sure that the chains are sufficiently oiled so
that they can travel freely. If a chain is too tightly tensioned, the product will be more difficult to pedal
and there is a big chance that wear and tear of the chain and sprocket, among other things, will occur
faster. If a chain is not tight enough, the chain can easily come off the sprocket, or there is a chance of
damage to the chain housing.
When both chains must be tensioned, always begin with the rear/short chain.
To tension the rear chain:
• Remove the protective hood.
• Loosen the nuts of the hub.
• Tension the chain by moving the hub forwards.
• Make sure that the hub remains exactly parallel to the rear axle.
• Tighten the hub nuts again.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.

Tensioning the front chain:
• Loosen the nuts of the crank axle at the bottom of the frame.
• Tension the chain by moving the crank axle forwards.
• Tighten the nuts again. It must be possible to push the middle of the chain upwards by 10 mm. Use
a screwdriver to check the tension on the chain through the slot on the bottom of the chain housing.
