clamp.
Align the handlebar and install the
stem clamp. Please set the bar a
little toward the rider.
Loosen the clamp bolt, align the
steering wheel and lock it again.
① Front wheel mounting
Remove brake wire holder and
release the brake.
Attach the front wheels to the forks.
There is no distinction between left
and right. Make sure that the bracket
ts securely into the hole of the fork
and lock it with the nut.
Loosen brake shoe nut, adjust the
brake shoe so that it is in parallel
with the rim, and set the wire to the
holder again.

③ Tire pressure
Pump air into the tires of the front
wheel and the rear wheel.
Use a small air inlet of the tip, or use
an adapter like the one on the right
side for easy operation.
Recommended air pressure: 200 to
250 kPa
⑤ Adjust lever position (for left and right)
Rotate the screw to adjust the
distance of the lever from the
handlebar to match the size of the
rider's hand. Clockwise rotation
brings the lever position closer
toward the handlebar.
Loosen the bolt to adjust the height
of the lever. Please set it so that it
is slightly lower than the horizontal,
and ne-tune according to the taste
of the rider.
When adjusting the lever height,
if the throttle cable and the lever
interfere with each other, loosen
the screw and rotate the throttle to
set it in a position where it will not
interfere.
④ Mounting the foot peg
Insert the foot peg as shown in the
picture. If the insertion is stiff please
turn while inserting.
Push the left and right foot peg covers
in. Insert the foot peg to the end,
adjust according to the shape, and

⑦ Adjust rear brake
Loosen nut A, push brake arm B
toward the front of the vehicle, pull
the wire in that position, tighten nut A
again.
Loosen nut A and rotate B to ne tune
the brake position. Turn clockwise
to bring the brake lever closer to
the front, counterclockwise to set it
further apart. After the position is set,
tighten nut A.
*In the beginning, brake function
may feel weak, but with use, it will
gradually break in for full braking
force.
After gripping the lever several times,
let the rear wheel spin. If you hear
scratching sounds, tighten or loosen
the screw A to nd the point where
the scratching sound disappears.
If this does not stop the scratching
sounds, loosen the nut B to the left
and right, and adjust the inclination
of the rear wheel. Tighten the nut
at the position where no scratching
sound is heard.
⑥ Adjust front brake
Loosen the wire locking nut, pull the
wire, adjust the distance between
the brake shoe and the rim to about
1 mm, and tighten the locking bolt.
Loosen nut A and rotate B to ne tune
the brake position. Turn clockwise
to bring the brake closer to the rim,
counterclockwise to set it further
apart. After the position is set, tighten
nut A.
Hold the lever and check that the
brake arm moves equally evenly on
both sides. If there is bias, adjust
with screws. Tightening the screw
will strengthen the arm's spring.

*The rider straddles the seat without the cushion at the lowest seat height ( ⑨ reference) on the 12-inch model, when
the height of the rider is 90 cm or less, or when the height of the rider is 100 cm or less in the 16 inch model. Please
straddle the bike in this situation and check your feet, if your feet are just right in this position, the seat cushion cannot

11. Gyro Sensor
Yotsubamoto Meow has a sensor that automatically cuts power off on falling.
Specically, if it is inclined by about 45 degrees in the horizontal direction, it is judged to
be in a falling state and electric power is cut. At that time, the indicator ashes on and off
to indicate sensor operation.
Motor will not operate even if the bike is stood up with the throttle open after falling.
Once the bike is standing, return the throttle to full close once to release the sensor. The
bike can now be ridden normally.
Warnning
- The Gyro sensor is effective only in the left-right direction. It is not affected in forward
and backward rotation direction.
- When the bike is completely upside down, the sensor judges that the bike is standing
and does not cut power. Therefore when the bike is stopped in the upside-down state,
the rear wheels may continue to rotate.
- Parents or guardians should keep their eyes on the rider while riding.
!

12. Storage and care
① When rinsing the bike with a shower, please do so with the bike standing.
Please avoid washing bike in a state where the bike is laid down or upside down, and
avoid high pressure washing.
② Heat speeds deterioration of the lithium ion battery. Please store indoors in cool area.
Especially avoid storage in the bike during the summer season.
③ Throttle is a non-disassemble item.
If sand etc. gets in and it does not move smoothly, please consult your authorized dealer.
④ When in storage for an extended period, please charge the battery to about half full and
store it avoiding high temperature and humidity areas. This will delay battery degradation.
⑤ When opening the bottom cover to remove water and sand, please do not insert / remove
the battery connector which has the possibility of leading to a serious accident.
⑥ Do not allow oil such as wax to adhere to the brake. This leads to lower braking function.
- Since the motor is waterproofed, it can not be disassembled. Please do not disassemble.
Maintenance is basically unnecessary due to the brushless motor.
- Never disassemble, penetrate, incinerate, crush, short circuit the battery.
Doing so may cause serious accidents such as a re. Also, please do not store in areas
where temperatures reach higher than 60 degrees.
