2.2 Maintenance activities
2.2.1 Frame
The frame is powder-coated or black zinc plated. To prevent any rust forming it is important
to regularly clean the frame. If you want to conserve the frame with grease, only use acid free
substances. You can treat damaged areas with paint.
2.2.2 Wheels/tires
Regularly check the rims and tires for any damage (for example cuts and wear).
Attention: damaged rims and tires can lead to accidents! The tires may not come into contact with
oil, grease or fuel.
2.2.3 Steering
The steering mechanism must be checked every month for the following:
• Damage and/or wear and tear to steering mechanism.
• All the nuts and bolts must be tightened.
2.2.4 Driving mechanism
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 the 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 the 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 chainguard 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.
• Tighten the four bolts again. Keep the sprocket wheel parallel to the chainguard.
• The chain has the correct tension if the middle can be pushed 6 millimeters downwards.
• Mount the chainguard when the chain has the correct tension.
The protecting cover has to be removed to grease the chain and check the chain tension. See next
page for images.
