D. First Ride
When you buckle on your helmet and go for your first familiarization ride
on your new bicycle, be sure to pick a controlled environment, away from
cars, other cyclists, obstacles or other hazards. Ride to become familiar with
the controls, features and performance of your new bike.
Familiarize yourself with the braking action of the bike (see Section IV.C.).
Test the brakes at slow speed, putting your weight toward the rear and
gently applying the brakes, rear brake first. Sudden or excessive applica-
tion of the front brake could pitch you over the handlebars. Applying
brakes too hard can lock up a wheel, which could cause you to lose control
and fall.
If your bicycle has toeclips or clipless pedals, practice getting in and out
of the pedals. See paragraph B.4. above.
If your bike has suspension, familiarize yourself with how the suspension
responds to brake application and rider weight shifts. See paragraph B.5.
above and Section IV.F.
Practice shifting the gears (see Section IV.D.). Remember to never move
the shifter while pedaling backward, nor pedal backwards after having
moved the shifter. This could jam the chain and cause serious damage to
the bicycle.
Check out the handling and response of the bike; and check the comfort.
If you have any questions, or if you feel anything about the bike is not
as it should be, take the bike back to your dealer for advice.
II. Safety
A. The Basics
1. Always wear a cycling helmet which meets the latest
certification standards and follow the helmet
manufacturer's instructions for fit, use and care of
your helmet. Most serious bicycle injuries involve
head injuries which might have been avoided if the
rider had worn a helmet.
WARNING: Failure to wear a helmet while riding may result
in serious injury or death.
2. Always do the Mechanical Safety Check (Section 1.C.) before you
get on a bike.
3. Be thoroughly familiar with the controls of your bicycle: brakes
(Section IV.C.); pedals (Section IV.E.); shifting (Section
IV.D.)(Section IV.C.); pedals (Section IV.E.); shifting (Section IV.D.)
4. Be careful to keep body parts and other objects away from the
sharp teeth of chainrings; the moving chain; the turning pedals
and cranks; and the spinning wheels of your bicycle.

SECTION: I First / SECTION: II Safety
WARNING: Never inflate a tire beyond the
maximum pressure marked on the tire's sidewall.
Exceeding the recommended maximum pres-
sure may blow the tire off the rim, which could
cause damage to the bike and injury to the rider
and bystanders.
The best and safest way to inflate a bicycle tire to
the correct pressure is with a bicycle pump which
has a built-in pressure gauge.
WARNING: There is a safety risk in using gas
station air hoses or other air compressors. They
are not made for bicycle tires. They move a large
volume of air very rapidly, and will raise the
pressure in your tire very rapidly, which could
cause the tube to explode.
Tire pressure is given either as maximum pressure or as a pressure
range. How a tire performs under different terrain or weather
conditions depends largely on tire pressure. Inflating the tire to
near its maximum recommended pressure gives the lowest rolling
resistance; but also produces the harshest ride. High pressures
work best on smooth, dry pavement.
Very low pressures, at the bottom of the recommended pressure
range, give the best performance on smooth, slick terrain such as
hard-packed clay, and on deep, loose surfaces such as deep, dry sand.
Tire pressure that is too low for your weight and the riding
conditions can cause a puncture of the tube by allowing the tire to
deform sufficiently to pinch the inner tube between the rim and the
riding surface.
CAUTION: Pencil type automotive tire gauges can be inaccurate and
should not be relied upon for consistent, accurate pressure readings.
Instead, use a high quality dial gauge.
Ask your dealer to recommend the best tire pressure for the kind of
riding you will most often do, and have the dealer inflate your tires to
that pressure. Then, check inflation as described in Section I.C. so
you'll know how correctly inflated tires should look and feel. Some
tires may need to be brought up to pressure every week or two.
Some special high-performance tires have unidirectional treads:
their tread pattern is designed to work better in one direction than
in the other. The sidewall marking of a unidirectional tire will have
an arrow showing the correct rotation direction. If your bike has
unidirectional tires, be sure that they are mounted to rotate in the
correct direction.
2. Tire Valves
There are primarily two kinds of bicycle tube valves: The Schraeder
valve and the Presta valve. The bicycle pump you use must have
the fitting appropriate to the valve stems on your bicycle.
