3.2.4 Chain
The product has a driving mechanism with one chain, which needs proper maintenance.
Make sure that the chain is sufficiently oiled so it can run smoothly.
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.
To tension the chain:
• Remove the plastic chain guard by loosening the bolts on the front side and the bolt on the rear
side.
• Untighten but do not remove the four bolts on the bottom side near the front sprocket.
• Tension the chain by moving the pedal axle forwards and hold it tight.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.
• Tighten the four bolts again. Keep the sprocket wheel parallel to the chain guard.
• Mount the chain guard when the chain has the correct tension.
• The chain guard has to be removed to grease the chain and check the chain tension.
