2. Safety
As an outdoor sport and auxiliary transport device,
serious injury may occur any time during riding. PLEASE
BE CAUTIOUS ALL THE TIME, LEARN AND PRACTISE
STEP BY SETP BEFORE YOU REGULARLY RIDE IT.
READ THE INSTRUCTIONS THROUGHLY AND
CAREFULLY to control the risk.
2.1 Important
⚫Do not make rapid acceleration or deceleration
or over incline forward or lean backwards.
⚫Do not use the EUC if there are any risks of
accidental fails.
⚫When there is alarm of over power, over voltage,
low battery, please decelerate at once.
⚫Please keep in mind deeply: most accidents are
caused by rapid acceleration or deceleration. So
please operate EUC properly to protect the
device and yourself.
2.2 Attention
⚫Please wear helmet, gloves. Elbow/Knee pads
or other protection garments.

make sure no parts are loose or damaged.
⚫When there are crowded pedestrians, please
slow down to match their walking speed.
⚫When carry the device, please make sure the
power is off.
⚫Do not put your fingers around the tire, to avoid
injuries caused by the tire running
⚫Do not ride on highways or any other prohibited
places.
⚫Do not ride on rough or bumpy surfaces, such as
muddy or pebbled roads
⚫Do not ride on wet, slippery surfaces, especially
snowy roads.
⚫Any person under 12 is strictly prohibited to use
the EUC.
⚫Do not ride in bleak winter conditions.
⚫Countermarch riding is dangerous. Try to avoid
countermarch unless safety guaranteed
⚫Don’t jump with the ECU
Other sudden unpredictable risks may occur during use,
please ride with care. KINGSONG electric unicycle will
not be responsible for any injuries caused by unproperly
operations on the device.

6. Basic Information
Can find the serial number, ride informaiton, battery
informaiton, and defect indications as belowing

7. Riding Mode
Riding Mode refers to be the ration mode during start-off
and breaking.
Experient Mode / Riding Mode / Learner Mode
At the beginning, ride at learner mode to feel the
accelerate and decelerate, turning and so on.
Riding mode and Experient mode is just for high
requirement rider who want to try more flexible
experience.
Experient mode can satisfy the group who wants to
perform skills like jumping, also it can avoid pedal tilt back
when climbing up or down steep hills.
8. Self-inspection and horizontal calibration
Firstly, switch on the EUC and keep it standing still on the
ground until it finds its balance. Then login APP and
connect with the wheel to check the device information.

4. Precautions and Preparation
4.1 Precautions
⚫Use the auxiliary belt to ensure safety driving
especially at the learning level. As the beginners,
can use auxiliary belt to prevent the unicycle from
scraping. Tie the belt to than handle of the EUC,
step one foot on the pedal, adjust the belt to a
proper length, once losing the balance & have to
jump off from the unicycle, you can drag the EUC
with the belt to protect it from sudden fall or broken
⚫The self-balancing EUC achieves balancing by
versus of the gyroscope. Rider leaning forward, the
unicycle will accelerate. Oppositely leaning
backward, the unicycle will decelerate to keep the
balance between the driver and the device itself.
⚫Like riding bicycle, you must keep left or right
balancing by your body and the riding speed.
⚫Do not ride on slippery or bumpy surfaces, friction
between the tire and the ground is essential to keep
the balance.
4.2 Practice Advice
⚫Find a proper ground.
⚫Warm up your body and be equipped with helmets,
elbow, knee supporters.
⚫Check battery level, shack the unicycle to avoid
potential unsafe factors like looseness, abnormal
sound, push the unicycle by hand to check whether
it exists frictions between the tire and body shell
⚫Find a friend to assist you if needed
⚫Tie the auxiliary belt to the handle, adjust it to a
proper length.
⚫Don’t speed up or slow down suddenly in order to
keep good maintenance, also don’t lean too much or
too fast to avoid sudden speed up&down, even
rider’s injury.
4.3 How to use
4.3.1 Start the unicycle
Grasp the handle with one hand, place the unicycle
vertically on the ground, and unfold the two treadles. If
the unicycle tilts either forward or backwards after power
is switched on, then wait until it reverts to upright position
before riding.
Press the power key to turn on the unicycle, the battery
level will illuminate and buzzer will beep, then the vehicle
is ready to use.

We suggest that you push the unicycle forward and
backward to get an idea of the intensity of acceleration
and deceleration.
If the unicycle tilts either forward or backward after power
is switched on, then wait unit it reverts to upright position
before riding.
4.3.2 Try to stand on the unicycle
Stand on the center of the treadle with your preferred foot,
so that you can lean your gravity center to the foot.
Stand up, use the foot on the treadle to control the forward
and backward balancing, and lean your shank on the
rubber plate tightly
Gradually lean your gravity center to the foot on the
treadle, a triangle support is required with your shank,
foot and the balancing unicycle，otherwise the it’s very
difficult to transfer the gravity center to the unicycle. If you
failed to transfer the gravity center, further riding is not
suggested.
4.3.3Go forward
For notice, like riding bicycle, transfer your gravity center
to the unicycle, tread the pedal forward slightly,
meanwhile, kick the other foot backward slightly, the
unicycle will go forward, try to keep balance during riding,
and gradually put the other foot on the treadle.
For intermediate learner, pay more attention to the
following two points: keep at a certain speed, control the
speed through leaning forward and backward. Try to
extend the riding distance by repeated exercises.
4.3.4 Turning
We found beginner tends to rotate the upper torso to turn,
to improve the efficiency, we suggest you to make it by
adjusting the tilt of treadles.
5. Battery
5.1 Temperature effect on battery

Battery power will vary with the temperature, mileage per
charge will have slight difference under different
temperature, following table is just for your reference.
5.2 Charging
The device has a built-in lithium battery, no extra battery
installation is required, just charge the device when it
indicates low battery.
Plug in the power source after inserting the charger plug,
this can prevent potential risk to ensure a safer charger.
It takes around 14h to get 100% charge (for 1554Wh with
1.5A standard charger), when the red lights turn into
green, indicating the charging is completed.
If not in urgent need, please wait until charging complete
before unplugging, because after charging, the protection
circuit will perform flow equilibrium

Battery level: A thirteen-bar LED indicator is used to
indicate battery level. All thirteen-bar LED will light up
when power level is reaching 100% and will go off one by
one as the level decreases. Please check power level
before usage to ensure there is enough power for the
return trip.
When power level is lower than 5%, all lights will flicker
and the buzzer will sound off. The front part of the treadle
will descend to force you to decelerate and eventually

stop. Please do not restart when this occurs to avoid any
accidents.
Sustained range will decrease during winter. This is
because the battery performance decreases quickly in
cold conditions in -15 ℃, for example, battery
performance is only about half in comparison to that in
room temperature.
6. Care and Maintenance
6.1 Conservation
Don’t place the unicycle in a wet condition
If left unused, recharge the battery at least once a month
to avoid the battery exhausted and maintain longevity of
the battery. Meanwhile, the battery can’t be dismantled
arbitrarily, in case of changing, pls contact us, we will
provide you with professional services
Clean the unicycle with wet cloths and detergent,
gasoline, solvent or any other chemical reagent are
forbidden.
Use the inflation tube to inflate the tire. Without the tube,
you will not be able to pump air into the wheel.
6.2 Change tire
All driver and cross screwdriver are required to change
tire
Unscrew all the screws on the body shell with cross
screwdriver, 7 screws each side.
There are 6 screws on each side under the treadles,
unscrew the six hex socket screws on the opposite side
of the charger slot, pls notice that never unscrew the hex
socket screws on the side of the charger slot.
After unscrewing the screws, rotate the shell body until
you can dismantle the tire freely, avoid pulling out the
electric cables around the handle area.
After repairing, install the body shell and fix the screws.
