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.

3.4 Riding Mode
Riding Mode refers to the torque during start-off and braking.
Expert Mode / Riding Mode / Learner Mode decelerate,

11
turning and so on.
Riding mode and Expert mode is for rider who want more
performance.
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.
3.5 Self-inspection and horizontal calibration
Firstly, switch on the EUC and keep it standing still on the
ground until it finds it’s balance. Then login to the APP and
connect with the wheel to check the device information.
4. Precautions and Preparation
4.1 Precautions
•Please find a smooth surface to practice on.
•Warm up your body and ensure you're wearing safety gear such
as helmets, knee pads, elbow pads and wrist guards.
•Ensure the wheel's battery level.
•Check the unicycle for imperfections such as any looseness,
abnormal sound. We also highly suggest pushing the unicycle
by ahnd to see if there's any friction between tire and the case

12
of the wheel.
•Have a friend assist you if required.
•Please do not accelerate or decelerate rapidly, please also try to
avoid over leaning or leaning too fast to prevent rider injury.
•Padding up the wheel during the learning process is highly
recommended to ensure minimal scrapes on the exterior of the
wheel.
4.2 How to use
4.2.1 Starting on the unicycle
Hold the wheel with one hand and ensure the wheel sits
vertically on the ground. Unfold the pedals and switch on the
wheel, it will self-balance forwards and backwards, if it does
not, please ensure the wheel is upright. Quick pressing the
power button once the wheel is on will toggle different light
modes.
4.2.2 Standing on the unicycle
With the pedals unfolded on both sides please stand on it with
your preferred foot in the center of the pedal. Balance the
wheel under you by keeping the other foot on the other side of
the wheel. If you are left footed, keep your other foot at around

13
5 o’ clock, and if you are right footed please keep the other foot
at around 7 o’clock.
If you are having a difficult time balancing the wheel under you
make sure you find a centre point of balance between these
three points: a) bottom of the tire b)where the top of you leg
touches the wheel c) your foot. Finding the balance point
between these three points will allow you to more easily
control the wheel under you.
4.2.3 Learning to ride forwards and braking
Whilst having the wheel balanced under you, use your
non-preferred foot to push off and lean forwards to begin going
forwards, once the wheel gets going please put your
non-preferred foot back onto the wheel. Focus on balancing and
not falling left or right. Try to look ahead rather than down!
Have your hands out to help you balance!
To come to stop simply lean backwards and the wheel will slow
down and come to a stop. You may dismount your
non-preferred foot when standing.
Note: The harder you lean forwards or backwards will dictate
the speed in which the wheel accelerates and decelerates.

14
4.2.4 Turning
When turning, lean your body gently to the side in which you want
to go and straighten up when you want to go straight again! As
you become more experienced at riding you will find other ways
to turn such as; letting the wheel fall just side to side, just turning
the lower part of your body, leaning your entire body. Advanced
riders will usually incorporate a combination of these.
