INFLATING THE TYRES
NOTE: The tyres are inflated when shipped, but they invariably lose some pressure
between the point of manufacturing and your purchase. Always inflate the tyres to the
correct PSI before first time use.
Please read the specification sheet to get the information of tyre pressure.
Using a bicycle-style tyre pump to inflate the tyre to the PSI indicated on the sidewall of
the tyre.
NOTE: The pressurized air supplies found at gasoline stations are designed to inflate
high-volume automobile tyres. If you decide to use such an air supply to inflate your
tyres, first make sure the pressure gauge is working, then use very short bursts to
inflate to the correct PSI. If you inadvertently over-inflate the tyre, release the excess
pressure immediately.
Important information of use guider for tyre
Note: Tyre is the only contact between the vehicle to the road, the safety of various
driving activity depends on the small area of tyre where it contacts with the road.
Therefore, it is very important to keep the tyre in good condition at all times and use the
correct size and standard tyre to replace the old ones.
Guide:
Tyre assembly and disassembly:
It is strongly recommended that the tyre assembly and disassembly should be done by
an authorized technician with necessary skills.
Tyre inflating pressure:
It is very important to keep the tyre in proper pressure and check the tyre pressure

before use. The inflating should be done while the tyre is cold.
Tyre maintenance:
Tyre tread depth should be checked regularly (shallower tread means less grip of tyre).
You must stop to use the vehicle if the tyre is pierced, disassemble the tyre and check it
carefully. Tyre maintenance should be done by an authorized technician. Tyre should
be replaced immediately when it is distorted or damaged.
Tyre replacement:
It is important to use the correct size and standard tyre as per our specification (see
details in technical specification sheet).
Don’t use the used tyre if you are not sure its previous service condition.
Tyre aging:
Tyre aging is unavoidable even the tyre is not ever used or just used a few times. Tyre
aging is mainly reflected in the cracked section on side of tyre and tyre tread,
sometimes the tyre is distorted as well. The used and aged tyre should be checked and
confirmed if it is ok to use again by an authorized technician.
BEFORE RIDING
Charging the Battery
You shall use the charger which should match this bike (never use a charger from a
different model). Before charging, you must turn the power switch to “OFF” and pull out
the key. Keep the charger in a dry and ventilative condition when it’s working.
The charger is designed for indoor use only. Keep the charger away from water to avoid
short circuit. Don’t even use it in a dampening, combustible or explosive environment.
Do not remove the plug by pulling the cord, always grip the charging port by its metal
body.
Firstly connect the output plug of the charger with the socket of the battery case
properly, and then insert the input plug into the AC electrical outlet. And the charger
indicator will light on, which means it’s on charging.
When the light turns from Red to Green, it means the battery has been fully charged.
Usually it will take about 4-6 hours to recharge the battery depend on different status.
However, it’s a good suggestion that it’s be charged for additional 2 hours after the light
turn to green if you have time (It is good for the service life of the battery).
Do not charge it for more than 10 hours to avoid overcharging and damaging the
battery. After the light turns GREEN, the charger is in the state of trickle electric current
and “fill slowly " and maintain the state. If you are going to be out for a long time, you

should pull out the charger plug, especially in hot weather.
The charger will become warm during charging, so keep charger away from any heat
source. Please always keep the charger dry and clean. The electronics inside contain
high voltage, so please don't disassemble the charger by yourself.
After charging, please pull the input plug out of the electrical outlet first, and then pull
out the output connecting plug from the battery case. Do not let the charger plugged
into the battery or electrical outlet for a long time, which may damage the charger and
cause the fire.
While charging, please keep it out of the reach of children. Do not put anything on top
of the charger when in use, and prevent any liquid, metal or metal fillings to permeate
into the charger.
You can also remove the battery from the bike and then charge it.
Do not touch any poles in the battery case with your hands when the battery is removed
for charging. Also the charging connector poles cannot be touched with any metal or
any other material that conducts electricity, otherwise it may cause short circuit.
If you don’t ride your bike for a long time, the battery should be charged at least one
time per month. This will ensure the battery life. DO NOT use in the state of low battery
capacity. Do not leave your battery in a fully discharge state for long periods of time.
The battery will continue to self-discharge, resulting in damage.
Avoid any contact with water when charging your battery. If a plug or socket gets wet,
dry it completely before using.
When charging, if there is a peculiar smell or the temperature is extremely high, please
stop charging immediately and send to the local distributor or to the Customer Service
Center.
WARNING: rechargeable batteries are only to be charged under adult supervision.
Always disconnect your electric motor bike from the charger before cleaning with
liquid.
NOTE: Chargers have built-in over charge protection to prevent battery from being over
charged. Charger will get warm during use, this is normal for some charges and is no
cause for concern. If your charges does not get warm during use, it does not mean that
it is not working.
Be sure to properly align the groove on the charger input port with the corresponding
socket on the vehicle and tighten threads; otherwise, no charging action will occur.

There are 2 charge port on this vehicle, one is located below the handlebar of battery box, and
the other is fitted on the left side of motor cover ( see above picture).
Warning: Failure to recharge the battery at least once a month may result in a battery
that will no longer hold a charge.
SAFETY REMINDERS
PRE-RIDE CHECKLIST
Loose Parts
Check and secure all fasteners before every ride. Make sure steering stem clamp bolts
are locked properly in place. There should not be any unusual rattles or sounds from
loose parts or broken components. If you are not sure, ask an experienced mechanic to
check.
Brake
Check the brake for proper function. When you squeeze the lever, the brake should
provide positive braking action.
Frame, Fork and Handlebars
Check for cracks or broken connections. Although broken frames are rare, it is possible
for an aggressive driver to bash into a curb or wall and wreck and bend or break a frame.
Get in the habit of inspecting yours regularly.
Tyre Inflation

Periodically inspect the tyres for excess wear, and regularly check the tyre pressure
and re-inflate as necessary. If you get a flat tyre, the inner tube can be patched or a new
tube can be purchased from an authorised repair shop.
Safety Gear
Always wear proper protective equipment such as an approved safety helmet, elbow
pads and kneepads. Always wear shoes (lace-up shoes with rubber soles), never drive
barefooted or in sandals, and keep shoelaces tied and out of the way of the wheels,
motor and drive system

Replacing The Fuse
WARNING:
To prevent shock, please follow above instructions accordingly and do not skip or
combine any steps.
Adjusting chain
Checking the drive chain periodically to ensure longer chain life.
Always keep it lubricated and tighten the chain as follows:

Step 1 Use the cross screwdriver to loose the 3pcs screws and remove the chain
cover.
Step 2: Loose the rear wheel axle nut with 17mm and 14mm open spanner, then loose
the screw of caliper bracket, adjust the chain adjuster.
Step 3: The chain tension is in good condition while the gap is about 5mm between
chain to lowest parts of swing arm. Lock all the nuts and screws, check the
wheel alignment and then re-attach the chain cover.
Adjusting brake
Step 1:
To adjust the brake tension, thread the brake lever
adjuster in or out 1/4 or 1/2 turn until the required
brake adjustments is attained.

Most of brake adjustments are complete at this step, if the brake still need the further
adjustment,
Step 2:
With 10mm open spanner, loose the brake cable
and adjust the brake caliper arm to make the cable
length>30mm from arm to the pillar.
Step 3:
With 8mm open spanner to loose the nut of
friction pad, and with 2.5mm allen wrench to
adjust the inner screw for friction pad.
Check
To check the wear of front and rear brake pads A, simply inspect the brakes calipers as
shown in the below picture. The thickness of the lining on the ends of the four
pads should never be less than 1mm.
Should the lining be thinner, immediately replace
the brake pads.
We recommend having the brake pads replaced by
an authorized dealer.
Warning:
The brake is capable of causing the electric bike to skid the tyre throwing an
unsuspecting rider. Practice in an open area free from obstacles until you are familiar
with the brake function. Avoid skidding to stop as this can cause you lose control or
damage the rear tyre.
Testing the Brakes
To use the brake, squeeze the lever to increase the pressure on the brake. The brake
lever is fitted with a cable adjuster to compensate for cable stretch and/or to fine-tune
the lever movement to brake engagement. If brake is not engaging properly, follow
instructions for adjusting the brakes.

Chain and sprocket
The chain will typically have a “loose spot”and “tight spot”corresponding with a
particular sprocket rotational position. This is normal and common to all chain-driven
products due to run-out to tolerance of the free wheel and sprocket. The chain should
be adjusted to the ideal tension with chain in the tightest spot.
Proper chain alignment must be maintained. The wheel must not be skewed, if the chain
is noisy or rough running, check the lubrication, tension and alignment of sprockets, in
that order.
Warning:
To avoid a pinch or injury, keep fingers away from moving sprockets and chain.
