Make sure you don’t have loose fasteners. Raise the front wheel about 10
cm from the ground, and let it jump on the ground.
Verify that no devices appear loose, checking its sound or at sight.
In case some accessories appear loose, tighten them with care. If you are
unsure, ask those who have more experience to have a check, or ask a
professional bike shop.
Tires and wheels:
make sure the tires are correctly inflated. Get on the bicycle and observe
the tire inflation after applying your weight.
Compare what you see with the appearance of the tires when they are
properly inflated and intervene if necessary, by inflating them.
Spin the wheel slowly and check that there are no cuts in the tire tread
and in the lateral part.
Before using the bicycle, replace any damaged tire.
To check the alignment of the wheels, turn one wheel at a time, then
check the contact between the wheel and the brake and check that the-
re are no lateral oscillations.
Make sure that the saddle and the stem are parallel to the central axis
of the bicycle and securely locked, so that it cannot rotate and lose the
alignment position.
Make sure that the handlebar grips are well fixed and in good condition.
If not, have them replaced.
Make sure that the handlebar is well inserted. In case, have it correctly
inserted at a retailer before using the bicycle.
