TABLE OF CONTENTS

Firstly, thank you for purchasing an OSET Electric Mini Motocross Bike. This is a serious piece
of machinery designed for use by children in fully controlled and safe environments.
As the purchaser/owner of the machine, YOU are the responsible adult with the
task of keeping the rider(s) safe at all mes. If you defer this task to another adult,
it is YOUR RESPONSIBILITY to pass this owners manual and all relevant informaon
to whoever will take on this role, and ensure without queson that the rider is
controlled and taught in a safe manner.
Your OSET is very adjustable and can be specically set up for the rider. Please
do not allow the machine to be used or adjusted by other children or adults. There are
likely to be many children asking for a ride. DO NOT ALLOW THIS TO HAPPEN. It is likely
you know the abilies, levels of concentraon and aenon span of the child you
purchased the machine for. EVERY CHILD IS DIFFERENT and it is impossible for you to
properly supervise other children.
Your OSET is driven by a powerful electric motor. The control dials MUST be adjusted to
suit the abilies of the rider. Please remember that even when the speed is set to
a slow seng, if the power and response are at high seng, the full torque of the
bike will sll be available. This means that opening the throle will propel the machine
to the set speed very quickly. Your OSET has great capabilies, and can grow with the
skills of the rider to very high levels, but it is IMPERITIVE that the responsible adult controls
the enre learning process and gives full aenon at all mes.
IT IS YOUR RESPONSIBILITY TO FORESEE ALL POTENTIAL SITUATIONS AND
CONTROL THE RIDING ENVIRONMENT ACCORDINGLY.
This means not just the machine and the rider, but also the riding terrain and environment.
Our machines are virtually silent, and can be used in many places that gasoline bikes can’t.
They are brilliant for praccing in back yards; front yards, garages, and even indoors!
OSET Mini Bikes are designed for o road use only and must not be used on public roads
or sidewalks. Please check and obey all local laws. OSETs may only be ridden in safe areas
where all laws are being followed and all required permissions are given.
OSET’s are amazingly capable, and can be used from the earliest stages of learning
to ride all the way through to o road compeons.
The secret of learning to ride well is being able to ride a lot. OSET’s enable this to happen,
and can make the learning process very grafying for both the children and the adults.
Thanks again for purchasing an OSET, and we hope you, and your child, will enjoy the ride!
Ian Smith, President, OSET CORP.
A WORD ABOUT THIS OWNER’S MANUAL AND SAFETY
INTRODUCTION
4
PLEASE READ THIS OWNER’S MANUAL PRIOR TO
OPERATIONS!
To ensure opmum performance from your new OSET, and to ensure safe operaon,
it is important to fully understand the features of the machine.
This manual contains IMPORTANT INFORMATION that every owner must fully understand.
If a child will operate your OSET, it is YOUR RESPONSIBILITY to set up the machine,
and make sure it is operated correctly and safely. Your OSET features a speed dial that sets
the speed from a walking pace to top speed. It also has a throle response ‘map’ dial.
This will set the throle response from very slow, up to very fast. The most important dial
is the power dial; the OSET controller is capable of outpung a lot of power.
This power should be treated with respect and must be learned. ALWAYS start the rider
at the slowest speed, response and power sengs. Even with a slow response,
a lot of power is available, and the rider must learn how to control it. These controls
must be set by the responsible supervising adult. Never allow the child to alter the sengs,
or to ride without suitable supervision.
Instrucng and praccing in a controlled situaon will allow the child to learn how
to operate the machine safely, and under control. The child’s enjoyment will be greatly
enhanced if they feel safe during the inial learning process. Please follow the instrucons
contained in this manual before operang the machine.

WARNINGS!
Failure to obey all of the warnings & instrucons contained in this manual may result in
serious injury or death and permanent damage to your OSET.
WARNING!
It’s up to you. We’ve done everything we can to supply you with a safe and reliable
product. Please read, understand and pracce the following guidelines for safe operaon
of your OSET electric motocross bike:
WARNINGS!
A high quality helmet approved by your country’s governing body is the single most
eecve way to reduce the severity of an injury in the event of an accident.
ALWAYS use an approved helmet when riding this vehicle. As this vehicle is intended for
OFF-ROAD use, there is a very high likelihood that dirt and other debris will be thrown into
the air, presenng the risk of eye injury if protecve eyewear is not used.
OFF-ROAD riding presents many hazards such as loose dirt and gravel, obstacles and other
dicult-to-see-and-avoid condions. The possibility of a fall is high. Wear gloves, wrist,
knee and elbow protecon. Failure to use appropriate safety equipment greatly increases
the likelihood of death or serious injury in the event of an accident.
WARNING!
WARNINGS!
Failure to maintain this vehicle in proper operang condion can lead to an accident
resulng in death or serious injury, and property damage. If you have any quesons about
the proper care and maintenance of this vehicle, consult your selling dealer/distributor or
contact OSET Customer Services at [email protected].
Before each ride, make sure that all bolts and nuts are fastened securely and that the res
are properly inated. Before each ride, check that the throle and brake controls are
operang freely. Adjust and lubricate the drive chain as necessary. See pages 18-30 of this
manual for addional details regarding service, repair and maintenance. Check the OSET
web site for maintenance guides.
This vehicle should be returned for periodic maintenance to your selling dealer AT LEAST
once per year, but more frequently if used under severe condions.
WARNING!
8
Always follow the Pre-Ride Checklist before every ride.
Do not operate your OSET if any damage is apparent.
Immediately contact your local retailer/distributor or OSET Customer Service.
• Supervision: Riders must be supervised by responsible adults at all mes. The rider
should never be beyond eye and voice range. An adult must ALWAYS assess and
approve the riding condions and the bike preparedness before the bike is ridden.
Always ensure the rider is cauous, maintaining complete control and a reasonable
speed. Ensure the terrain is suited to the skills of the rider.
• Helmets & Safety Are: There is no single factor that works beer at reducing the
severity of injuries sustained in accidents more than a quality helmet. Please don’t
ever allow your OSET to be ridden without one. Riders should also wear suitable
riding gear - gloves, eye protecon and boots. Boots should NOT HAVE LACES. Shoe
laces and loose clothing, or even long hair could potenally get caught in wheels,
chains, or sprockets.
• One Rider Only: Your bike was engineered to carry one rider and no (0) passengers.
Carrying a passenger would overload the machine and alter the handling. Do not
allow this to happen.
• Do not overload the bike: OSET’s are designed for small, lightweight riders. Ex-
ceeding the weight limitaons will adversely aect the handling of the machine, and
potenally cause damage.
• It’s the law; obey it: Obey all laws. OSET’s are for OFF-ROAD USE ONLY. OSET bikes
can not be used on public roads or sidewalks. The purchaser, owner, and/or riders of
this machine are directly responsible to know and obey all local, state, and federal
laws regarding the riding and use of this machine.
• Night me: Don’t ride aer dark or in low light condions.
• Weather & Riding Condions: Bike brakes don’t work well when they’re wet. Don’t
ride in the rain or snow. Please be aware that distance to stop may double or triple
over the distance that it takes under dry condions. Ride more slowly, and ancipate
your stops by applying the brakes MUCH earlier. Don’t allow children to ride on
slopes that are too steep for their ability.
• Maintenance: It worked ne when we put it in the box: please maintain your bike.
There are instrucons here in this manual. We haven’t gured out how to make a
bike that takes care of itself.
Check the brakes and the res and the ghtness of all those important fasteners
before each and every ride. Pretend that you’re a pilot doing a walk-around of his
airplane before taking-o. The pilot knows that his life depends on the airworthiness
of his airplane; the rider’s life depends on the preparedness of their bike.
Please have your bike checked by a qualied mechanic AT LEAST once a year.
It’s a small investment in the well-being of the rider.

DIALS & INDICATORS
This dial must only be changed by a responsible
adult. When dial is turned to the fully clockwise
posion, the bike will have a maximum speed,
when in the an-clockwise posion the speed will
be reduced to its minimum.
Reducing this seng is ideal to set the bike up for
beginners & younger riders.
DIAL ADJUSTMENT
The bike’s adjustment dials are located beneath the
small black panel which also houses the key switch.
To remove the panel, twist the fastener and li the
front of the panel up and towards the handlebars.
SPEED DIAL
This is the most important adjustability feature on
the bike and must ALWAYS start with the lowest
seng, and make changes in very small increments.
It may appear that the highest power will be
suitable for an advanced rider, but it must be
understood that there is a lot of power available.
It is a great feature to have such a range available,
but it MUST be treated with respect. ALWAYS
adjust from lower to higher, in small increments.
POWER DIAL
It must be treated very carefully as the range of
adjustability is enormous.
THIS DIAL IS TO BE ADJUSTED BY A RESPONSIBLE
ADULT ONLY.
The funcon of this dial is to adjust the ‘response’
of the bike.
Fully an-clockwise will give the slowest throle
response. Fully clockwise will give the quickest
response.
THROTTLE RESPONSE DIAL
DIAL PANEL REMOVAL
16
It is very important to keep everyone clear of the bike when changing and checking the
speed and response sengs. The dial is sensive to small adjustments. Do not guess at
changes. Always check before the rider gets back on to ensure the desired seng is
correct for the abilies of the rider.
WARNING!
DRIVE CHAIN
Your OSET features a tradional chain and sprockets. It is direct drive, with no gears.
With the motor mounted in the swing arm, suspension movement has no eect on tension.
However, the chain does need to be checked and adjusted regularly, especially when the
bike is new.
The chain must be checked before every ride and adjusted as necessary. There should be
very lile slack in the chain. Adjustment is done as follows:
1. Ensure power is turned o.
2. Loosen axle nuts (shown opposite).
3. Turn chain tensioner nuts evenly on both sides. Very small movements can make a
big dierence. Do not ghten so much there is no slack at all.
It should be ‘taught’, not ‘ght‘. Rotate wheel by hand and check chain tension.
4. Lubricate the chain & check the sprocket bolts for ghtness.
5. Reverse the above procedure, ensuring all bolts are ght.
6. Check the wheel for alignment and the chain for tension. See pages 17 & 20 for
wheel alignment informaon.
Failure to maintain and adjust the chain and align the wheel correctly could result in the
chain jumping o the sprockets, causing a potenally dangerous and damaging condion.
WARNING!
17
These two pictures show the correct tension.
When pushing up on the chain’s ghtest point, it should only move by 5-10mm.
Axle Nut (19mm) Chain tensioner nut (13mm)
The OSET motor has been designed for high performance. DO NOT POWER WASH THE
MOTOR. Check that the sprocket bolt is ght periodically. Waterproof grease can be
applied around the sha where it enters the motor for addional protecon from the
elements. Similarly, a bead of silicone can be applied where the casings join for addional
weather protecon.
MOTOR PERFORMANCE & MAINTENANCE
The motor can get hot. It is designed to withstand high temperatures. However, sustained
maximum output is not recommended. The motor is designed to withstand pulses of
maximum output, not sustained.
WARNING!

SUSPENSION
OSET bikes feature adjustable front and rear suspension. The available adjustability is a great
feature. Separate owner’s manuals are provided. Please read for further informaon on how
to best set up the suspension.
The front suspension is an ‘air’ fork. A specic air pump is required to add pressure which can
be purchased from your local OSET dealer. The fork is also adjustable for rebound & preload
via two simple dials located on the top of the fork.
FRONT SUSPENSION FORKS
Preload Dial. Rebound Dial. Suspension Air Pump.
Your OSET bike is equipped with a single
coil spring type rear shock. For a harder/
ser ride at the rear ghten the
adjustment ring in a clockwise
direcon.
For a soer ride, loosen the adjuster by
turning an-clockwise. It also features a
very eecve rebound dial.

WHEEL REMOVAL AND INSTALLATION
Please refer to the secon on assembling your OSET bike (page 12) for informaon on
installing the front wheel, and reverse the instrucons for removal.
FRONT WHEEL
1. Ensure power is switched o and the key removed.
2. Li the bike onto a block or stand so the wheels are o the ground.
3. Loosen the axle bolts (see image 1.)
4. Loosen the chain adjustment nuts to the point where the wheel can be pushed
forward, and the chain slipped o to the right of the sprockets (image 2 & 3).
5. Pull back on the wheel to remove it.
REAR WHEEL
(1.) (2.)
(3.) (4.)
6. To re-install the wheel reverse the above procedures. Ensure the chain is correctly
adjusted and lubricated, the wheel is aligned, and all nuts and bolts are ght
(image 4).
21
BRAKE ADJUSTMENT
The brakes are self adjusng to a point, but correct alignment is vital to get the maximum
performance. The pads must be equidistant from the disc for maximum eciency.
Visually inspect the pads as you spin the wheel. Check that alignment is good and pad to disc
distance is even. If adjustments are needed follow the instrucons below:
• Using an Allen wrench, loosen the calliper mounng bolts, allowing the calliper to
move freely from le to right.
• With the bike raised, spin the wheel before pulling the brake lever. This will allow the
calliper to ‘centre’ on the disc.
• With the lever sll holding the pads ghtly on the disc, re-ghten the calliper bolts.
• If the wheel does not spin freely with the brake released and further adjustment is
required beyond the limits of the built in adjustment, the calliper posion itself can be
adjusted further by the use of spacer washers. In this way, the calliper can be lined up
perfectly.
Loosen calliper. Squeeze lever.
Inspect pads. Adjust lever reach.
The brake levers can be adjusted for ‘reach’. Use a small 2mm Allen key.
Turn an-clockwise to bring the reach closer to the bar (for smaller hands).
22
SIDE PANEL & BATTERY REMOVAL
• Ensure power is turned o, and remove the key.
• With the side panel already removed, unscrew & disconnect the power lead (image 4).

BATTERY CARE & DISPOSAL
Your OSET features a 48v drive system, for use with a sealed 48V lithium baery.
Under NO circumstances should this baery box be opened by anyone other than a
trained OSET technician.
Doing so can damage the baery and/or bike & will void any warranty.
OSET recommend using a ‘mulmeter’ to
monitor the health of the baery. You will be
able to easily and instantly see the charge of
the baery.
In order to test the baery voltage using a
mulmeter, connect the negave & posive
probes to a pair of pins on the discharge port
on the baery as shown.
A mulmeter is also very useful in diagnosing
any electrical problems on the bike.
We are condent that you will enjoy many miles of pleasurable riding with your OSET
electric bike baeries. However, baeries do eventually wear out.
When this happens, we urge you to properly dispose of your used baeries.
For guidance regarding proper disposal of your baeries, please contact your local dealer,
distributor or the customer service department at OSET.
In the USA you can nd very useful informaon regarding used baery drop-o sites from
the Rechargeable Baery Recycling Corporaon (RBRC) at www.rbrc.org or through their
ocial program www.call2recycle.org.
For UK customers, please visit www.recyclenow.com to nd your local recycling centre.
BATTERY DISPOSAL
When tesng the baery voltage, you should have a reading of between 34.0 & 54.4V
depending on the state of charge of the baery. If you read anything outside of this
range, please disconnect the baery immediately and contact your OSET dealer,
importer or OSET customer services.
27
MAINTENANCE, CLEANING & STORAGE
• Keep your OSET clean and dry. Clean using the recommended procedure (see be-
low).
• Check all components for ghtness and adjustment, including handlebars, levers,
axles, chain, brakes.
• Check the wheel spokes for ghtness. It is normal for spokes to loosen in
operaon. PLEASE CHECK aer every inial ride, and then regularly aerwards.
If you need guidance please consult a skilled wheel builder or call OSET customer
services.
• Check the speed, power and response seng before each ride.
• Check the res for proper inaon. Also, inspect the res for damage.
CLEANING
Cleaning and maintaining your OSET correctly will provide a more enjoyable ownership
and riding experience. By hand cleaning the bike, you can simultaneously inspect all of the
components. We recommend cleaning be done with a damp cloth and slow running wa-
ter.
Care must be taken when washing. This is an electric machine and water should never
reach sensive components. If a hose is used, cover sensive parts.
Water and electrical components do not mix! Do not get water onto the controller,
throle or wiring. Failure to follow this instrucon could result in permanent damage, and
WARNING!
LONG TERM STORAGE
MAINTAINING YOUR OSET

WIRING
Your OSET is an electric bike, and features a considerable number of electrical components
and wiring. All must be protected from water and dirt! The components are listed below:
Controller: Shown below. This is the ‘brains’ of the drive system. It is a sophiscated and com-
plex component and is non-serviceable.
Throle: This sends an electronic signal to the controller, which is then interpreted to de-
termine the power required and the voltage to be sent to the motor. The throle is a non-
serviceable component. It must be protected from water.
The throle contains a small circuit board that can be damaged by water. Similarly, the
connecon between the throle and controller must be protected from water at all mes.
Baeries: There is one, sealed lithium baery included with the OSET bike.
Motor: The motor is the end of the line where the power is actually delivered. The motor is
made up of many components. Any servicing must be carried out by trained technicians only.
Please do not aempt to separate or dismantle the motor in any way.
Relay: The relay is acvated by the switch. It makes a 48v connecon that allows power to be
pulled from the baeries to the controller and ulmately to the motor. The relay has con-
necons that should not be touched unless the baeries are disconnected. The relay is a non-
serviceable item. Shown below.
Several other components make up the electrical system, such as the switch, the charge port,
the speed switch, the response dial etc.
There are no user serviceable elements incorporated into the motor, controller, baeries,
baery charger, throle, or wiring harness of your OSET electric bike. DO NOT ATTEMPT
TO DISASSEMBLE OR ADJUST ANY OF THESE COMPONENTS. Doing so may cause extensive
damage to these components, will void your warranty, and may cause a hazardous
condion. If you cannot resolve a problem using this owners manual, contact your
OSET authorized dealer, or call the OSET Customer Service Department for assistance.

SETTING UP YOUR OSET FOR RIDING
1. Set the speed dial to the correct level for the rider.
Low for non-experts and all riders under 10 years old.
ALWAYS CHECK BEFORE RIDING.
2. Set the ‘response’ dial to the correct level for the rider.
Low for all non-experts and all riders under 10 years old.
ANTI-CLOCKWISE for low. CLOCKWISE for high.
3. Set the ‘power’ dial to the correct lever for the rider.
Low for non-experts and all riders under 10 years old.
ANTI-CLOCKWISE for low. CLOCKWISE for high.
A. Ensure everyone is clear of the bike.
B. Place the bike on a stand or block, so both wheels are above the ground.
C. Switch the bike on.
D. Turn speed dial to low. Set to high for experienced/advanced
riders over 10 years old ONLY.
Turn the power dial in very small increments to the desired seng. ALWAYS start the rider on
the slowest sengs!
4. Check the res are inated to between 20 & 40 psi. Light riders can run lower
pressures.
5. Check the chain for ghtness and lubricaon.
6. Set the controls correctly for the rider.
A. With the wheels on the ground, sit the rider on the bike.
B. Adjust the lever posions so they are easy to reach, and check that the
brakes are funconing correctly, and at the desired level. Adjust the ‘reach’
of the levers to suit the rider. For more informaon see page 19.
Improper set-up is dangerous! It is your responsibility to set the machine to the ability of
the rider. Failure to do so could result in serious injury or death, and damage to
the machine.
WARNING!
32
NOTE
As the responsible adult, you must ensure that the OSET and its rider are ready to ride, every
me. The bike must be set to the abilies of the rider, and you must ALWAYS supervise when,
where and how the bike is ridden. Children can lose concentraon quickly, and be distracted
easily. If the speed or throle response is set too high then loss of control could result.
STATIONARY LEARNING
RIDING INSTRUCTIONS & SAFETY TIPS
1. Ensure the key switch is in the o posion.
2. Li the machine on to a stand or block so the back wheel is an inch or two o the
ground. Ensure the bike is stable and cannot be rocked or fall o the stand.
3. Sit the rider on the machine.
4. Explain all the controls:
A. Throle
B. Front Brake (right hand side).
C. Rear Brake (le hand side).
Have the rider pracce each control, while the power is sll o.
5. Explain that it’s me to try some staonary pracce, with the power turned on. Place
the rider’s feet either on the pegs, or on the ground. Either way, make sure the rider is
wearing boots with no laces, and no loose clothing.
6. Start with both hands on the handlebars.
7. With the power on, and the riders hands on the bars, have the rider pracce opening
and closing the throle. The aim is to get some throle control, and not use it as an
‘on-o’ switch. This is very important.
DO NOT RIDE UNTIL THIS HAS BEEN LEARNED FULLY.
8. While sll praccing the throle, pracce using the rear brake to stop the back wheel.
Make sure that this is coordinated. The throle and brake should not be applied
simultaneously.
UNTIL THESE SKILLS ARE MASTERED, DO NOT LET THE CHILD RIDE THE BIKE!
BEGGINERS & LEARNERS
With the bike set up correctly, your OSET is ready to ride! For learning riders, please use these
ps and instrucons. The riders will get the most enjoyment if they feel safe and in control.
Do not be tempted to start the riders too quickly. Make sure the speed and response are set
to their slowest sengs to begin.
NOTE
If the rider does not fully understand the controls and demonstrate these skills, do not let
them ride. They can try again at a later date when they are ready. The riders must learn at
THEIR pace.
33
FIRST RIDE
Do not exceed the abilies of the rider! Only allow competent riders with full instrucon
to ride the bike. Do not allow inexperienced riders on the bike before they have
demonstrated a complete knowledge of the controls. Always start on the slowest sengs.
WARNING!
Aer the rider understands the controls and is comfortable with them, it’s me for the rst
ride. For this, the rider must be dressed correctly in suitable safety gear. Boots, gloves, a
helmet and eye protecon are necessary.
The venue must be at, open and safe, with no obstacles of any kind. The machine must be
set up correctly, with the speed set to its lower seng and the throle response set to its
lowest.
1. Ensure the power is turned o.
2. While an adult supports the bike, the rider can get on.
3. The rider should now be able to sit on the bike, with both feet comfortably touching
the oor and with their hands on the handlebars.
4. Encourage the rider to rock the machine from side to side and forward and back, in
order to get comfortable with the weight of the bike.
5. The rider can now switch the machine on.
6. Before turning the throle, the rider’s legs can be splayed forward and out like
outriggers.
7. The rider can now twist the throle (as slowly as possible) and go. Encourage them to
go and stop, go and stop… using the brakes to stop. Have a supporve hand on the
rear fender whenever possible.
8. Once comfortable, the rider can try to ride along and li their feet onto the pegs as
they go.
9. When stopped, turn the power o.
If the rider drops the bike, ensure that the power is turned OFF before liing the bike. It is
good pracce to turn the power o whenever there is no rider on the bike.
CAUTION
OFF ROAD USE ONLY!
OSET Mini Bikes are designed for o road use only and must not be used on public roads
or sidewalks. Please check and obey all local laws.
WARNING!
34
LEARNING TO STAND UP
Once the basics are mastered, the bike response can be adjusted to match the growing skills
of the rider. Always use cauon when adjusng the bike to faster response sengs.
Any changes must be small and incremental. Do not change the sengs in big chunks on the
assumpon the rider can handle it. LEARN SLOWLY!
Before the rider gets going too fast it’s a good idea to get them riding the bike ‘correctly’. This
means, standing up and in control. Learning to stand up is very dicult if the skill set of the
rider does not include good throle control.
1. While the machine is staonary and the rider is on the bike, have an adult stand
behind and support the rider at their waist.
2. The rider must posion themselves correctly, posioning their head over the
handlebars in a crouching stance. This will help enable the rider grip the bike with
their legs for beer control.
3. When the rider is ready, they can open the throle, smoothly and in control. An adult
should run along and help support when necessary.
4. Once the rider is up and running in the standing posion, leaning forward with their
elbows scking out away from their body, it’s me to learn some technique.
NOTE
A common error (in our view) is to put children on machines that are too big. Please note the
rider should be able to touch the ground securely with their feet & reach the handlebars
with ease. If the machine is too large for the child, they will have no leverage on the bike,
and be unable to develop techniques. To develop correct technique, the rider is beer o
being too big than too small.
35
LEARNING SOME TECHNIQUE
Learning some correct riding style techniques will put the rider in a great posion for all forms
of riding that come later. A good rider learns how to control the machine at slow speeds and
use correct skills to execute ght turns and other techniques. Many riders tend to think that
the way to turn is to simply turn the handlebars. This is natural, but wrong! If ght turns are
mastered correctly, many other skills will follow on naturally.
1. Riding in a straight line, the rider can pracce leaning the bike to one side, then to the
other. They will noce that when they do this, the bike will want to turn.
2. To execute a ght turn, lean the bike to the inside.
3. Lowering their inside leg whilst cornering can help weight distribuon. It is advisable
they keep a straight leg and point their toes up whilst doing this.
4. Whilst turning, it is vital the rider is aware of their surroundings, including obstacles &
other riders.
5. Once the turn is complete, the rider can then put their foot back on the peg.
Once seated turning is mastered, many other techniques will follow. Turning with this level of
skill requires full control over the machine. It will not be possible without the rider under-
standing all the intricacies of balance, body posion, and throle control.
NOTE
A surprising amount of technique can be completely natural for children. In many cases, the
riders simply work out what works best, and go with it. Simple instrucons like “lean it in”
will oen iniate everything else being done correctly. The more exaggerated this technique,
the beer it will work. If a child can master cornering they are likely to become great riders.
Viewing MX instruconal videos may also help. Many children can learn simply by watching.
This manual should be enough to get you started. Further techniques cannot be covered in
this manual. When learning any technique the most important thing is to do so slowly and
safely.
Enjoy the ride!
