BIKE INSPECTION BEFORE EVERY
RIDE
Before every ride, inspect the bike with the following
check list. If any part of the bike fails the inspection,
repair the bike by following the information provid-
ed in this manual or take the bike to your bike shop
for service. Never ride a bike with a damaged part;
have it replaced.
Check the tire
inflation
- Make sure to
check tire pressures
using a tire pressure
gauge. The tires
should be set be-
tween 7psi and 15
psi caution never
set below 7psi or
above 15ps.
Tires and Wheels
- Spin each wheel and check that the tires are in good
shape with no cuts or abrasions. If these are found,
replace the tire immediately.
- Inspect the rim for trueness by spinning it and
watching for any side-to-side or up-and-down wob-
ble. If any movement is noted do not ride this bike
until the rim is repaired.
Wheel Retention System
Some bike wheels are
designed with quick
release attachments
and others are bolt-
ed directly on using
a hex-nut. There are
3 main methods of
attachment as listed
below:
1. A hollow axle with a
“skewer” shaft running
through it which has a nut on one end and an over-
the-center cam on the other end.
2. A hollow axle with a “skewer” shaft running
through it which has a nut on one end and a hex-key
or other tightening device on the other end.
3. Hex nuts or Hex key bolts are threaded into or on
to the hub axle.
Brake Reach
Some bikes have adjustable brake levers. These can be
adjusted to fit each individual rider’s specific needs.
For example, if you have a short reach you may need
the levers adjusted closer to the handlebar. This ad-
justment or brake lever replacement should be done
by a qualified bike technician or bike shop.
Handlebar stem and front wheel alignment
Make sure the front wheel and handlebar stem are
aligned in the proper orientation of each other.
Turn the handlebar from side to side with the front
wheel locked between your knees to test the stem
connection of the fork. If any movement is noted do
not ride the bike until this is corrected.
Inspect cable routing to be sure the handlebars can
turn freely without binding or pinching the cables.
Check to be sure that your handgrips on the han-
dlebars are in good condition and the bars are not
protruding through the grip.
Seat Position
The saddle should be adjusted for proper fit and is an
important factor in riding safely.
Place your pedals in the 6 o’clock and 12 o’clock po-
sition. Your bottom leg should be very slightly bent
when the ball of your foot is placed on the lower ped-
al. If it’s bent too much you need to raise the saddle.
If you have to rock your hips to reach or can’t easily
reach, you must lower the saddle.
Ensure that the saddle is straight and level.
Seat and seat post
Check that the seat is securely mounted on the seat
tube by lifting up and down on the seat. This should
WARNING
!
A wheel attachment device that is not properly
adjusted and closed may allow the wheel to be
loose or come off unexpectedly, causing you to lose
control and fall. Make sure the wheels are properly
attached before riding the bike.
CAUTION
!
Disc brakes and discs get very hot during use and
could burn skin. Also, the disc edges may be sharp
and could cut skin. Avoid touching the disc or disc
brake when hot, or when rotating.
