Thank you for purchasing an OSET Electric Trials 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.
This manual contains IMPORTANT INFORMATION that every owner must fully understand to
ensure opmum performance from your new OSET, and to ensure safe operaon, it is
important to fully understand the features of the machine.
If you defer this task to another adult, it is YOUR RESPONSIBILITY to pass this owners manual
and all relevant informaon to whoever will take on this role, and ensure without queson
that the rider is controlled and taught in a safe manner.
Your OSET is very adjustable and can be specically set up for the rider. This motorcycle is
equipped with a speed liming device to restrict top speed. Use this device unl your child
becomes familiar with the operang of the motorcycle. Please do not allow the machine to
be used or adjusted by other children or adults. It is likely you know the abilies, levels of
concentraon and aenon 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 abilies of the rider. Please remember that even when the speed is set to a slow seng,
if the power and response are at high seng, the full torque of the bike will sll be available.
This means that opening the throle will propel the machine to the set speed very quickly.
Your OSET has great capabilies, and can grow with the skills of the rider to very high levels,
but it is IMPERATIVE that the responsible adult controls the enre learning process and gives
full aenon 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.
OSET’s are amazingly capable compeon-ready bikes, and can be used from the
earliest stages of learning to ride all the way through to o road compeons. 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 grafying 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.

HOT SURFACES
During extended periods of use or if your OSET is ridden hard then some parts will get hot,
see highlighted areas in the image below.
- Do not touch the brake rotors or motor before they have cooled down.
- Let the bike cool down before carrying out any work.
INTENDED USE
Your OSET has been designed to be used in sports motorcycle compeons, or in a
supervised and authorised pracce environment.
Please follow all safety notes in the manual and ensure riders are of the correct age and
weight, the bike is correctly maintained, riders are always supervised and the bike is ridden
in appropriate condions.
SAFETY MODE
If the motor gets too hot the controller will limit the power to the motor unl the
temperature reduces to a safe level. If the motor temperature reaches a level which may
damage the motor then all power to the motor will be removed. Allow the bike to cool for
15 minutes , turn the bike o/on and you will be able to resume riding.
If the controller believes that an electronic component is behaving abnormally it will enter a
safe mode and stop power to the motor. If this occurs, stop riding and check the bike for
obvious signs of damage or faults. Once you have resolved the problem to restart the bike
you simply need to turn the bike o and on again. If the problem persists please take your
bike to an authorised OSET dealer for inspecon.
Risk of burning. Allow bike to cool before touching hot
surfaces.
WARNING

Always follow the Pre-Ride Checklist before every ride.
Do not operate your OSET if any damage is apparent. Immediately contact your authorised
OSET retailer/distributor or OSET Customer Service.
Supervision: An adult must ALWAYS assess and approve the riding condions and the
bike preparedness before the bike is ridden. Always ensure the rider is cauous,
maintaining complete control and a reasonable speed. Ensure the terrain is suited to the
skills of the rider.
Helmets & Safety Are: Do not allow your OSET to be ridden without a helmet
approved by your countries’ governing body. Riders should also wear suitable riding
gloves, eye protecon and boots. Boots should NOT HAVE LACES. Shoe laces and loose
clothing or even long hair could potenally get caught in wheels, chains or sprockets.
Do not overload the bike: Exceeding the weight limitaons will adversely aect the
handling of the machine, and potenally cause damage.
It’s the law; obey it: Obey all laws. OSET bikes 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, regional, and naonal laws
regarding the riding and use of this machine.
Do not sit on the bike when side stand is engaged in the downwards posion; This can
lead to damaging your machine, and yourself
Ensure charger is disconnected from bike before riding. Failure to do so will cause
damage to the bike and could result in injury.
Night me: Don’t ride aer dark or in low light condions.
Weather & Riding Condions: Bike brakes don’t work well when they’re wet. Please be
aware that distance to stop may double or triple over the distance that it takes under dry
condions. Ride more slowly and ancipate your stops by applying the brakes MUCH
earlier. Don’t allow children to ride on slopes that are too steep for their ability.
Before each ride, make sure that all bolts and nuts are fastened securely and that the
res are properly inated. Check that the throle and brake controls are operang
freely and adjust/lubricate the drive chain as necessary.
Please have your bike checked by a qualied mechanic AT LEAST once a year. It’s a small
investment in the well-being of the rider.

3. Remove all the packing materials.
4. Using the supplied Allen keys, make sure the steering stem is in the forward facing
posion and ghten the top and side bolts securely and evenly to 12nm.
Secure the handlebars ghtly in the steering stem. Double check ghtness and
alignment. Adjust the brake lever posions and reach to suit the rider.
5. Fit front mudguard using the bolt & washers provided (picture 1).
6. Fing Front Wheel.
Remove disk pad spacer (picture 2 - this item is used for transport only, keep this if
you are likely to leave the bike without the front wheel ed).
(1.) (2.) (3.)
7. Loosen top calliper Allen bolts (picture 3 - using 5mm wrench) - so it will move side to
side so as to aid ng of wheel.
8. With one axle bolt already screwed into the axle, hold the front wheel in the fork
lowers & slide the axle in through the hub. (picture 4 - ensure the pinch bolts on the
front of the forks are already loose).
9. Tighten the two pinch bolts on the side of the fork from which you inserted the axle
(picture 5).
(4.) (5.) (6.)
10. Replace locking bolt on the other side of the axle & ghten (picture 6).

11. Finally, ghten to remaining two fork pinch bolts on the fork lower.
12. Spin the front wheel and apply the front brake. Do this twice. While holding the front
brake on - ghten calliper bolts. This will centre the calliper and help to give even
wear of the pads and free running of the front wheel.
13. Adjusng rear calliper. Ensure rear wheel is clear of ground and turn by hand and
check brakes are not binding. If they are, loosen cap screws and adjust.
Be aware that because the wheel can be moved back and forth for chain adjustment the
calliper does also - so make sure it does not rub on the outer diameter of disc.
14. Install the front number plate using the supplied ‘zip-es’. This aaches to the
handlebars and the forks (picture 7).
17. Unpack charger (if supplied) from its box and read pages 21-23 of this manual.
Charge the baeries while thoroughly reading the rest of this owners manual.
(7.) Zip-es (8.) (9.)
15. Check re pressure of both res and conrm they are properly inated to 20-40 psi.
Light riders can use lower pressures.
16. The baeries are not connected for shipping purposes and will need connecng. It is
vital that connecons are made correctly. The baery strap should be ed before
connecng the main baery lead. Install the baery as indicated (picture 8 & 9).
18. Compress and check each brake lever in turn. The lever should not compress
completely to the bar. Each individual brake should hold the bike securely when you
push the OSET against the brake. If your brake needs adjustment, follow the
instrucons on page 19. Learning riders should be aware which lever operates which
brake.
19. For maximum baery life, always fully charge before operang your OSET for the rst
me and never store with discharged baeries. (See page 22-23).
20. While your baeries are charging, please Read Your Owners Manual completely.

DIAL ADJUSTMENT
THESE DIALS ARE TO BE ADJUSTED BY A RESPONSIBLE ADULT ONLY.
SPEED DIAL
Speed liming device for novice riders
This motorcycle is equipped with a speed liming device to restrict top
speed. Use the device unl the rider becomes familiar with operang
the motorcycle
The speed dial is located underneath the rubber bung for convenience.
This must only be changed by a responsible adult. When dial is turned to
the fully clockwise posion, the bike will have a maximum speed, when
in the an-clockwise posion the speed will be reduced to its minimum.
POWER DIAL
This is the most important adjustability feature on the bike and must
ALWAYS start with the lowest seng, 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 very small
increments.
THROTTLE RESPONSE DIAL
It must be treated very carefully as the range of adjustability is
enormous.
The funcon of this dial is to adjust the ‘response’ of the bike. Fully
an-clockwise will give the slowest throle response. Fully clockwise
will give the quickest response.
Always check the dial sengs before the rider gets back on to ensure the desired seng is
correct for the abilies of the rider. The dials are sensive to small adjustments, do not
guess at changes.
CAUTION
Keep clear of all moving parts when checking dial sengs. Failure to do so could result in
serious injury.
WARNING

14
KEY SWITCH
The key switch turns the power on and o. When the rider is sing
on the bike, this is located in front of them above the tank cover.
The key is removable, and should be removed when the bike is not
in use.
KILL SWITCH
This switch is in addion to the key switch and provides extra func-
onality. To enter the on posion place magnec top cap on base.
The key switch MUST be in the ‘on’ posion for the magnec kill
switch to operate.
With the key switch in the ‘on’ posion, the kill switch can be used to
turn the bike on by simply connecng the red magnec cap to the
black base on the handlebar, to turn the bike o using the kill switch
remove the magnec red cap from the black base on the handlebar.
As a safety precauon, if the throle is applied before the kill switch
is connected, the bike will not move.
Always ensure the rider is wearing the kill switch around their wrist
and that the cord is ghtened rmly.
DIAL PANEL REMOVAL
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.
The baery charge indicator is located on the throle assembly and
shows the state of the baeries. The indicator lights can be checked
at any me to determine if the main power is o or on. Always turn
the power o and remove the key when the bike is not in use.
NOTE
Now your OSET is fully assembled, adjusted and checked. Once the baeries are fully
charged, your OSET will be ready to ride safely.
CHARGE INDICATOR

15
Your OSET features a tradional chain and sprockets. It is direct drive, with no gears.
With the motor mounted in the swing arm, suspension movement has no eect 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 lile 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 dierence. 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.
These two pictures show the correct tension.
When pushing up on the chain’s ghtest point, it should only move by 5-10mm.
Entanglement Hazard. Turn power o before starng
work.

Please refer to the secon on assembling your OSET bike (page 11) for informaon on
installing the front wheel, and reverse the instrucons for removal.
Your OSET bike is equipped with a single coil
spring type rear shock. For a harder/ser ride
at the rear ghten the adjustment ring in a
clockwise direcon.
For a soer ride, loosen the adjuster by turning
an-clockwise. It also features a very eecve
rebound dial.
Oponal springs are available from your OSET
dealer to adjust the spring rate.
Entanglement Hazard. Turn power o before starng
work.
WARNING
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 informaon on how to
best set up the suspension.
The front suspension is an ‘air’ fork. A specic 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.

The brakes are self adjusng to a point, but correct alignment is vital to get the maximum
performance. The pads must be equidistant from the disc for maximum eciency.
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 instrucons below:
• Using an Allen wrench, loosen the calliper mounng bolts, allowing the calliper to
move freely from le to right.
• With the bike raised, slowly spin the wheel before pulling the brake lever. This will allow
the calliper to ‘centre’ on the disc.
• With the lever sll 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 posion 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).
