TIRES AND WHEELS:
Ensure that the tires are properly inflated (refer to the Quick Start
Guide for instructions). To check the tire pressure, place one hand on
the saddle and the other on the intersection of the handlebars and
stem. Bounce your weight on the bike while observing the tire
deflection. Compare the deflection with how it should look when the
tires are correctly inflated and adjust as necessary.
Are the tires in good condition? Spin each wheel slowly and inspect
the tread and sidewall for any cuts or damage. It is important to
replace damaged tires before riding the bike.
Are the wheels true? Spin each wheel and check for brake clearance
and any side-to-side wobble. If a wheel wobbles slightly, rubs against,
or hits the brake pads, it is recommended to take the bike to a
qualified bike shop for wheel truing. Truing wheels require special
tools and experience, so it is not advisable to attempt it unless you
have the necessary knowledge, experience, and tools.
Bicycle wheel rims are subject to wear. Some rims have a rim
wear indicator that becomes visible as the braking surface
wears down. If a rim wear indicator is visible on the side of the
wheel rim, it indicates that the rim has reached its maximum
usable life. Riding a wheel that is at the end of its usable life
can result in wheel failure, leading to loss of control and
potential accidents.
NOTE
Ensure that the wheel rims are clean and undamaged. Check
the cleanliness and inspect for any damage at the tire bead. If
you have rim brakes, also inspect the braking surface. Ensure
that no rim wear indicator markings are visible at any point on
the wheel rim.
WARNING
BRAKES:
Check the brakes for proper operation. Squeeze the brake levers and
ensure that the brake quick-release mechanisms are engaged. Verify
that all control cables are seated and securely engaged. If you have
rim brakes, confirm that the brake pads make solid contact with the
wheel rims and fully engage within an inch of brake lever movement.
You should be able to apply full braking force without the levers
touching the handlebar. If adjustments are needed, do not ride the
bike until the brakes are properly adjusted by a professional bicycle
mechanic.
• Ensure that the front and rear wheels are securely fastened in the
wheel retention system.
• If your seat post has an over-center cam action fastener for easy
height adjustment, check that it is properly adjusted and locked in
position.
• Confirm that the saddle and handlebar stem are parallel to the
bike's center line and tightened sufficiently to prevent twisting or
misalignment.
• Check that the handlebar grips are securely attached and in good
condition. Ensure that the handlebar ends and extensions are
properly plugged. If you have bar end extensions, make sure they
are tightly clamped to prevent any twisting.
It is crucial to replace any handlebar grips, end plugs, or
extensions that are loose or damaged. These components can
expose the ends of the handlebars, posing a risk of injury and
potentially leading to loss of control and falls. Additionally,
handlebars or extensions that are not properly plugged can
cause cuts and serious injuries, even in minor accidents.
Therefore, it is important to ensure that all handlebar
components are securely in place to maintain rider safety.
