VII. TECH
(3) If you disengaged the brake mechanism in 3. a. (1) above, re-
engage it to restore correct brake pad-to-rim clearance. Do this by
re-tightening the nut the affixes the brake cable to the brake. Ensure
that cable length is properly adjusted so that the brake pads are fully
functional when the brake levers are engaged. Ensure the cable is
properly secured and held firm by the nut.
WARNING: The braking mechanism is critical to the safe operation of
your MOZIE bicycle. Improper installation or assembly of the front brake may
result in brake failure, which can cause you to lose control and fall. Contact
your qualified local bicycle shop for assistance with the proper removal and
installation of all braking mechanisms.
(4) Spin the wheel to make sure that it is centered in the frame and
clears the brake pads; then squeeze the brake lever and make sure that
the brakes are operating correctly.
d. Installing a roller brake Front Wheel (Hub assembly)
Front roller brakes are complicated to remove, repair and install safely.
If your MOZIE bicycle comes with a roller brake on the hub of the
front wheel (Marc models), we recommend you take your bicycle to a
qualified local bicycle shop for removal, repair, and installation.
WARNING: Do not attempt to remove, repair or install the front wheel
assembly or roller brake on your own. A qualified bicycle technician should be
used to complete these tasks. Incorrect removal or assembly can result in brake
or gear failure, which can cause you to lose control and fall.

Removing and Installing a Rear Wheel with internal gears an a roller
brake
MOZIE Bicycles come standard
with internal gear rear hubs

. Due the sophistication of
these components we suggest you
contact a qualified bicycle shop
before attempting to remove the
rear wheel.
B. SEAT POST BOLT
Your MOZIE Bicycle comes with a
traditional bolt system that secures the seat tube around the seat post.
Ensure the seat post bolt is securely fastened in accordance with the
toque specification in Appendix A
WARNING: Riding with an improperly tightened seat post can allow the
saddle to turn or move and cause you to lose control and fall. Therefore:
1. Ask a qualified bicycle shop or contact MOZIE Bicycles to help you make
sure you know how to correctly secure your seat post.
2. Before you ride the bike, first check that the seat post is secure.
C. BRAKES
MOZIE Bicycles utilizes two different types of braking systems:
1. Rim brakes, which operate by squeezing the wheel rim between
two brake pads; and
2. Roller brakes, which use a ring of rollers pushed outward by a cam
to engage the brake shoe with the braking drum
Both are operated by way of a handlebar mounted lever.
WARNING: 1. Riding with improperly adjusted brakes, worn brake
pads, or wheels on which the rim wear mark is visible is dangerous and can
VII. TECH
result in serious injury or death. 2. Applying brakes too hard or too suddenly
can lock up a wheel, which could cause you to lose control and fall. Sudden or
excessive application of the front brake may pitch the rider over the handlebars,
which may result in serious injury or death. 3. See the brake manufacturer’s
instructions for operation and care of your brakes, and for when brake pads
must be replaced. If you do not have the manufacturer’s instructions, see
your qualified local bicycle shop or contact the brake manufacturer. 4. If
replacing worn or damaged parts, use only manufacturer-approved genuine
replacement parts.
1. Brake controls and features
It’s very important to your safety that you learn and remember which
brake lever controls which brake on your bike. Traditionally, the right
brake lever controls the rear brake and the left brake lever controls the
front brake; but, to make sure your bike’s brakes are set up this way,
squeeze one brake lever and look to see which brake, front or rear,
engages. Now do the same with the other brake lever.
Make sure that your hands can reach and squeeze the brake levers
comfortably. If your hands are too small to operate the levers
comfortably, consult with MOZIE Bicycles before riding the bike. The
lever reach may be adjustable; or you may need a different brake lever
design.
MOZIE Bicycles equipped with rim brakes do not have a “quick release”
mechanism. The braking cable is secures to the brake pad controls
by a bolt. It is important to ensure this bolt is properly installed and
tightened, and the braking cable is appropriately secured at the proper
length. Your qualified bicycle shop can properly inspect and adjust your
brake cable.
2. How brakes work
The braking action of a bicycle is a function of the friction between the
braking surfaces. To make sure that you have maximum friction available,
keep your wheel rims and brake pads or the disk rotor and caliper clean
and free of dirt, lubricants, waxes or polishes.
Brakes are designed to control your speed, not just to stop the bike.
Maximum braking force for each wheel occurs at the point just
before the wheel “locks up” (stops rotating) and starts to skid. Once
the tire skids, you actually lose most of your stopping force and all
directional control. You need to practice slowing and stopping smoothly
without locking up a wheel. The technique is called progressive brake
modulation. Instead of jerking the brake lever to the position where
you think you’ll generate appropriate braking force, squeeze the lever,
progressively increasing the braking force. If you feel the wheel begin
to lock up, release pressure just a little to keep the wheel rotating just
short of lockup. It’s important to develop a feel for the amount of
brake lever pressure required for each wheel at different speeds and
on different surfaces. To better understand this, experiment a little by
walking your bike and applying different amounts of pressure to each
brake lever, until the wheel locks.
When you apply one or both brakes, the bike begins to slow, but your
body wants to continue at the speed at which it was going. This causes
a transfer of weight to the front wheel (or, under heavy braking, around
the front wheel hub, which could send you flying over the handlebars).
A wheel with more weight on it will accept greater brake pressure
before lockup; a wheel with less weight will lock up with less brake
pressure. So, as you apply brakes and your weight is transferred forward,
you need to shift your body toward the rear of the bike, to transfer
weight back on to the rear wheel; and at the same time, you need to
both decrease rear braking and increase front braking force. This is even
more important on descents, because descents shift weight forward.
Two keys to effective speed control and safe stopping are controlling
wheel lockup and weight transfer. Practice braking and weight transfer
techniques where there is no traffic or other hazards and distractions.
