Owner’s Bicycle Identication Record
NOTE: This information is only available on the bicycle itself. It is not available from Huy.
Each Huy bicycle has a Recovery Code
stamped into the frame. The Recovery Code
can be found on the bottom of the crank
housing as shown.
Write this number below to keep it for future
reference.
If the bicycle is stolen, give this number and
a description of the bicycle to the police.
This will help them nd the bicycle.

Recovery Code:
Purchase Date:
Model Name:
To determine the correct size of bicycle for the rider:
• Straddle the assembled bicycle with feet shoulder width
apart and at on the ground.
• There must be at least 1 inch (2.5 cm) of clearance 
between the highest part of the top tube and the

Warning and Safety Information
The Owner’s Responsibility
WARNING: This bicycle is made to be ridden by one rider at a time for general
transportation and recreational use. It is not made to withstand the abuse of stunting and
jumping.
If the bicycle was purchased unassembled, it is the owner’s responsibility to follow all
assembly and adjustment instructions exactly as written in this manual, and any “Special
Instructions” supplied and to make sure all fasteners and components are securely tight-
ened.
NOTE: Periodically check that all fasteners and components are securely tightened.
If the bicycle was purchased assembled, it is the owner’s responsibility, before riding the
bicycle for the rst time, to make sure the bicycle has been assembled and adjusted ex-
actly as written in this manual, and any“Special Instructions” supplied and to make sure all
fasteners and components are securely tightened.
NOTE: If product is assembled, please proceed to the following sections:
• Testing Seat Clamp and Post Clamp Tightness
• Testing Stem and Handlebar Tightness
Introduction
Meanings of Warnings:
This symbol is important. See the word “CAUTION” or “WARNING” which follows it.
The word “CAUTION”is before mechanical instructions. If you do not obey these instruc-
tions, mechanical damage or failure of a part of the bicycle can occur.
The word “WARNING” is before personal safety instructions. If you do not obey these in-
structions, injury to the rider or to others can occur.
• CHOKING HAZARD. Small Parts. Not for children under 3 years.
• Adult assembly is required.
• Continuous adult supervision is required.
• Do not add a motor to the product.
• Do not tow or push the product.
• Do not modify the product.
• Replace worn or broken parts immediately with original equipment.
• If anything does not operate properly, discontinue use.
WARNING - FREEWHEEL RIM BRAKES:
• Some models do NOT have a foot (pedal) brake.
• Ensure your child understands and can operate the hand brakes.
• Always use both hand brakes when stopping the bike.
• When stopping, apply front and rear brakes evenly.
• An unstable condition can occur if the front brake is used too hard resulting in injury to
the rider or others.

5
Rules of the Road
WARNING: Failure of the rider to obey the following “Rules of the Road” can result
in injury to the rider or to others.
• Obey all traffic regulations, signs, and signals.
• Always wear a bicycle helmet that meets safety standards, as well as local safety standards.
• Ride on the correct side of the road, in a single le, and in a straight line.
• If possible, avoid riding at night, dusk, dawn and any other time of poor visibility.
• If you must ride at night or at time of poor visibility:
• Purchase, install, and use a headlight and taillight.
• Headlights are required by all states for nighttime riding and taillights are required in
some states.
• Battery-powered lights or ashing safety lights are also recommended.
• Reectors: For your own safety, do not ride the bicycle if the reectors are incorrectly
installed, damaged, or missing. Make sure the front and rear reectors are vertical. Do not
allow the visibility of the reectors to be blocked by clothing or other articles. Dirty reec-
tors do not work well. Clean the reectors, as necessary, with soap and a damp cloth.
• Make yourself more visible to motorists.
• Wear light-colored or reective clothing, such as a reective vest and reective bands
for your arms and legs.
• Use reective tape on your helmet.
• Do not let anything cover the reectors.
• Use extra caution in wet weather:
• Ride slowly on damp surfaces because the tires will slide more easily.
• Allow increased braking distance in wet weather.
• Avoid these hazards to prevent loss of control or damage to your wheels:
• Be aware of drain grates, soft road edges, gravel or sand, pot holes or ruts, wet leaves, or
uneven paving.
• Cross railroad tracks at a right angle to prevent the loss of control.
• Avoid unsafe actions while riding.
• Do not carry any passengers.
• Do not carry any items or attach anything to your bicycle that could hinder your vision,
hearing, or control.
• Do not ride with both hands o the handlebar.
• Do not add a motor to the product.
• Do not tow or push the product.
• Do not modify the product.
• Replace worn or broken parts immediately with original equipment.
• If anything does not operate properly, discontinue use.

Testing Stem and Handlebar Tightness
To test the tightness of the stem:
• Straddle the front wheel between your legs.
• Try to turn the front wheel by turning the handlebar.
• If the handlebar and stem turn without turning the front
wheel, realign the stem with the wheel and tighten the
stem bolt(s) tighter than before (about 1/2 revolution only
at a time).
• Do this test again, until the handlebar and stem do not
turn without turning the front wheel.
To test the tightness of the handlebar clamp:
• Hold the bicycle stationary and try to move the ends of
the handlebar forward and backward.
CAUTION: Do not exceed 100 lbs (45 kg) push force.
• If the handlebar moves, loosen the bolt(s) of the
handlebar clamp.
• Put the handlebar in the correct position and tighten
the bolt(s) of the handlebar clamp tighter than before.
• If the handlebar clamp has more than one bolt, tighten
the bolts equally.
• Do this test again, until the handlebar does not move in
the handlebar clamp.

Assembly
WARNING: To prevent the Seat Acoming loose and possible loss of control, the
“MIN-IN” (minimum insertion) mark Bon the Seat Post must be below the top of the Seat
Tube C.
SEAT AND SEAT POST SETUP:
1. If needed, loosen Nuts on Seat
Clamp Dand rotate Seat into rid-
ing position.
2. Ensure the Seat Post Eis fully
through the TOP Seat Clamp D.
3. Tighten the Seat Clamp so the Seat
does not move on the seat post.
4. If the Seat Clamp has a Nut on each
side, tighten both nuts equally.
5. Point the Seat forward and put the
Seat Post Einto the Seat Tube C
and proceed to next step.
TIGHTEN THE QUICK RELEASE LEVER:
NOTE: The words “open”and “close”are on opposite sides of the quick release lever.
CAUTION: Operate the Quick Release Lever F
by hand only. Do not use a hammer or any other tool to
tighten the quick release lever.
1. Move the Quick Release Lever Fto the “open” posi-
tion so the word“open”is pointing away from the Seat
Post Clamp G.
WARNING: You must use strong force to move
the quick release lever to the “close”position. If you can
easily move the lever to the “close”position, the clamping
force is too light. If the clamping force of the Quick Release
Lever is too light, the seat post can loosen while riding.
This can cause injury to the rider or to others.
2. Open and close the Quick Release Lever with one hand while you turn the Adjusting Nut
Hwith the other hand.
3. Tighten or loosen the adjusting nut by hand, so that you rst feel resistance to the quick
release lever when it perpendicular to the bicycle frame.
4. Push the Quick Release Lever to the “close” position.
5. When in the “close” position, make sure the Quick Release Lever lays against the Seat

to install the pegs.
• Put a peg Aon each end of the
axle.
• Make sure the peg is fully seated
against the frame or fork. Tighten
the peg securely.
• Pegs will go over the axle nuts B.
WARNINGS:
• Do not ride beyond your capa-
bilities.
