* Precautions when using electronic brake immediately after full battery charge
The electronic brakes do not operate when the battery is fully charged, so be sure to
check and operate this device. When the battery runs out, the electronic brake will operate
normally.
* Precautions when using the ABS function
ABS has the advantage of being able to stop at the shortest braking distance that can be
obtained from the tires and road conditions. However, due to the principle of repeatedly
holding and releasing the brake several times in a second, a lot of vibration occurs in the
motor and the body. Repetitive vibration caused by this may cause frequent loosening of
the motor, rim, fixing part and body fixing bolt.
* ABS brake is an abbreviation of Anti-Lock Brake System. It uses the principle that maximum static
friction force is larger than kinetic friction, so that braking distance (distance from breaking to
stopping) is shorter than that of normal brake. It has the advantage that the vehicle does not slip
well when wheel is rotating.andit is a brake assist system that can stop more safely without wheel
lock and slip.
(1) ABS function ON
Set the ABS function part Pd of the dashboard to 1.
(2) ABS function OFF
Set the ABS function part Pd of the dashboard to 0.
* Pd - When the ABS function is ON,
the PA - electronic brake function is canceled.
All electric motorcycles are subject to sudden braking, causing the wheels to stop spinning. As a result,
the slip of tire causes the driver to fall down, which can cause accidents. This product is equipped with ABS
brake function to hold the tire lock, enabling more secure braking.

• Check the front and rear tires for wear and punctures and check the proper air pressure
(45 to 50 psi) for the tire. When the shortage of air is shortened, the possibility of
puncture increases, so check always.
• It is necessary to judge the replacement time by observing the appearance of the tire
such as tire damage, uneven wear.
3. Check tire pressure and uniaxial condition
• The brake braking force is sufficient to check the operating condition. If the braking force is significantly
lowered, use it immediately after inspection and action.
• Check that the brake pad is not worn, that the cable is not loose, that the cable is not
damaged, or that there is no leakage in the case of hydraulic brakes.
• If there is an unusual feeling or noise during operation, check for breakage, wear and
deformation of the inner wire of the brake cable.
• Check that the bolts and nuts of the brake fixing parts are not loose, and that the disc
is not deformed or damaged.
2. Check brake and cable
1. Check throttle and handle
• Operate the accelerator throttle lever about 2 ~ 3 times to check whether it returns
to the home position.
• Be careful that excessive throttle leaning and manipulation of the throttle can cause
malfunction due to internal parts damage.
• Check the fastening condition and clearance of the QR lever on the handle.
• Make sure that the bolts and nuts of all parts of the product are tight and free from
loosening. Check the fastening condition and clearance of the folding and fixing
parts of the handle (QR lever, fixed slide, hinge center bolt, headset nut, swing
arm, etc.).
4.Tightening check such as folding part and handle part
Danger
*If there is a folding clearance,
If there is a folding clearance, it can be adjusted with a tongue bolt. However, if
you pull it too hard, it will become stiff without a gap, but it may sound 'crackling'.
In this case, if you adjust the tune bolt properly, the noise disappears and the
clearance is also adjusted.
If you encounter any of the following situations while driving, stop driving immediately and
contact your nearest branch or service center for proper measures. If you provide pictures and
videos to get accurate diagnosis, professional counseling is available..
●Unusual heating of the motor
●Brake braking status error
●Error messages on the instrument cluster
●When the throttle is returned to its original position
●When the throttle is returned to its original position
* In this case, stop driving immediately.
Danger
●abnormal noise is generated
●Product smoke, ignition, sour odor
● When rain or wet with water or in a similar situation
●When other driving is judged to be unreasonable

1. Brake adjustment method
As you continue to use the brakes, the brake pads become
worn out and the gap between the pads and the brake disc
becomes wider. If the braking force drops, use a 5mm
hexagon wrench to loosen the brake arm wire bolt, then lift
the brake arm upwards to adjust the braking force.
2. Tire replacement method
1. After removing the calipers, remove the motor using 18mm
spanner and disassemble the wheel and motor fastening bolts.
2. Remove the wind from the tires and press the tires off the wheel.
3. Replace the tires and complete the assembly of the tires in
reverse order. Tighten the assembled tire to fit the body, then
tighten the screws and bolts.
*caution
●After completing the tire replacement, try a simple test run with
the appropriate air pressure (45 to 50 psi).
●When puncture is occurred, it is possible to use repair by using
patch seal. Please use the tire while checking and checking
continuously.
Important notice
3) Maintenance by self-maintenance
D U AL T R ON
* Metal vibration may occur due to motor vibration, vibration of the brake disc and pad
during the load section that accelerates during driving. (About 15 ~ 30Km, different for
each product)
This is a phenomenon in which all revolutions (fans, automobiles, ships, etc.) are
vibrating at a specific rotational frequency (rpm) rather than the product. However, if
the continuous noise or metal noise is large, there is a possibility that the disk is bent
and deformed.
* Please note that after running, there is a risk of burns due to the heat on the motor
and brake (especially disk rotor) side.
* Be careful that the bolts of the motor, rim and motor shaft due to the ABS function
may be loosened.
Important notice
* Completely separable hub motor design By designing the rim and hub
motor to be completely separable it is possible to replace only the rim
without replacing the entire motor when the rim breaks, thus improving the
maintenance and maintenance of the product. (Patent pending)
Easy-wheel system
3. Causes and countermeasures of disc brake noise
The disc braking method uses a disc brake method with many
electric kickboards because braking power is good. However,
if you get a sharp hissing sound when you hold the disc brake,
dust or sand particles on the ground will spill out on the surface
of the disc, causing foreign substances to be on the brake pads
or disc surface, or bending due to heat or external impact. At
this time, clean the inner surface of the disc by turning the
wheels with a clean, dry cloth, or straightening the bent discs.
4. Variable rubber suspension system (patent pending) adjustment
Designed by MINI Motors, the world's largest 45-step adjustable (3x3x5) rubber suspension system
allows you to adjust the suspension strength with motor shaft distance (3 steps), arm angle (3 steps),
and rubber cartridge replacement (5 steps).
1. Remove the front fender with a 3mm hex wrench, loosen the 18mm (motor side), 19mm (swing arm
side) nut, and then loosen the nut to remove the suspension arm.
2. Adjust the motor shaft distance, rubber cartridge replacement, and arm length to the desired
suspension strength.
■Motor shaft distance (3 steps): Height
adjustent (by weight)
You can adjust the height from the center.
■
Rubber Replacement (5th Stage): Replace
Cartridge (Adjust height by weight)
Loosen both nuts with a wrench, loosen 3mm
bolts and remove. Replace the cartridge when it
is missing.
(It can be changed depending on weight and taste)
3. Align both suspension arms to the desired angle and reassemble using Loctite (screw lock).
If the above measures are not taken, please visit the nearest branch and take a
safety check. There may be another problem.
