1.2 Notes
The electric bike is designed based on the original bike in
combination with the market demand and is a means of transport
with special functions and uses. At the time of purchase, please
select and buy a model suitable for your need, and the drivers must
have skilled riding technique before riding on the road. In order to
your correct use and security, please pay attention to the following
matters:
In the process of use, pay attention to check the fastening status of
the motor and rear fork, and if a loose phenomenon is found, it
should be tightened timely.
When starting the power supply or meeting a steep slope, use the
Pedal to assist as far as possible to reduce the starting current and
extend the battery life and continuation line mileage.
In rainy days, please pay special attention to: when the water depth
is more than the wheel center, it is likely for the motor to soak water,
thus resulting in failure.
Users must use the charger specified by manufacturer for charging
the storage battery. When charging, put the battery and charger
smoothly.
It is prohibited that other items are covered on the battery box and
charger to impede heat, where good ventilation environment should
be maintained.
Please keep appropriate air pressure inside the tires, so as to avoid
increasing the resistance when riding, and easily wearing the tires
and deforming the Rim.
Drivers should observe the traffic regulations, and the riding speed
should be controlled below 25km/h and the goods to be carried shall

not exceed 25Kg.
When high-speed running or downhill hard braking, do not use the
front brake to avoid the center of gravity from moving ahead, thus
resulting in danger.
Don’t modify the luggage carrier.
Don’t pull a trailer on the luggage carrier.
The bicycle may behave differently (particularly with regard to
steering and braking) when the luggage carrier is loaded;
Ensure that any luggage or child-seat fitted to the luggage carrier is
securely fitted in accordance with the manufacturer’s instructions
and that there are no loose straps that can get caught in any of the
wheels;
When luggage is attached to the luggage carrier, don’t obscured the

4.3. Introduction to speed boosting system
The speed boosting system is also known as 1:1 boosting system. And the
so-called 1:1 automatic power assisting is that when you do not rotate the
speed handlebar but ride only by means of feet, the sensor with you bike
will automatically sense your riding speed and control the motor to assist
you automatically in a driving force with the same speed, so as to let your

ride easier and make the continuation line mileage further.
1:1 boosting system comprises a controller, sensor and induced
cartridge.

4.4. Charge
As it will last a certain period of time for the ex-factory, transport and
storage of a just purchased new bike, it is likely to result in shortage of the
battery power, the battery should be first charged before it is used.
The charger configured or designated by our company must be used for
charging; otherwise it might damage the battery, and may even lead to fire
and other danger, but no warranty is provided by our company.
4.4.1. Installation and charging of battery（as shown in Figure 1 and
Figure 2）

Electric Bicycle Manual
11
4.4.2. Charging steps and method
1. Check carefully whether the rated input voltage of the charger is
consistent with the voltage of the power grid.
2. The battery can be directly put on the bike for charging.
3. Connect first the output plug of the charger with the charging jack of
the battery properly, and then connect the input plug of the charger to the
AC power supply.
4. At this time, the power indicator light and the charge indicator light of
the charger are on, indicating that the charging has been connected.
5. After charging, should first pull out the AC power plug, and then pull
out the plug connected with the battery.
After the battery is fully discharged, the one-time charging time is 4 to 6
hours, and after the charge indicator light is red from green, the power
capacity of the battery has been basically sufficient.
A new bike had best be re-charged for (6 to 7 hours) after depth
discharging since charging for the first time, and the one-week depth
charging and discharging is a cycle to fully activate the active substances
inside the battery. Later, it can be re-charged even if its power is not used

up.
Common sense of charging and use:
* The battery should be charged in a spacious environment, staying away
from high temperature, high humidity and close fire, because the battery
and the charger are electronic products, high temperature and humidity
will corrode electronic components, resulting in some harmful gases and
soot, and even a possible explosion to wound.
* The charging time should not be too long. A long charging will lead to
shortened life expectancy of the battery.
* After the battery is fully charged, the power supply should be pulled out
as soon as possible, and at the same time, the battery is taken out of the
charger.
* When the battery is not used for a long term, the battery power should be
emptied before the battery is preserved, and it is re-charged once every
month or so.
4.5. Quick release folding system
4.5.1. Quick release system of the seat
1. Move the quick release handle to
the OPEN position (OPEN sign faces
to the operator).
2. Clockwise rotate the adjusting nut,
only until it contacts with the seat
connector, and then turn a circle or
semi-circle in the opposite direction
and push the quick release handle to
the CLOSE position (as shown).
3. Push the side position of the seat head and the upper part by force; if
the seat rotates upward at the left and right or downward from up to down,

Electric Bicycle Manual
13
should first check whether the seat bunch is locked, and then check
whether the quick release device is locked, and repeat the operations
above if necessary.
4.6 Reflection and lighting system
The reflection system includes a reflector on the rim and another one on
the hand lebar. These items help to mark your own position when riding,
convenient for pedestrians and other vehicles on the roads to avoid
(recommendation: purchasers in accordance with local laws and
standards use the reflector and lighting system).
4.7 Seat position
When you sit on the seat to tread on the
Pedal flatly by heel, when the Pedal is
at the lowest position, legs slightly
stretch, and at this time it is the most
appropriate height; if the rider can tread
on the Pedal only by toes or legs can
not stretch slightly, fatigue and sports
injury will be caused, so there is a
careful need for adjustment of the height of the Seat post.
The Seat post has a MAX marked line (that is, the safety line), and the

Electric Bicycle Manual
14
so-called insertion mark can not be higher than the seat connector. In
case of improper use, serious injury may be caused to the rider (as shown
in Figure 2).
4.8 Braking system
The braking system is an accessory necessary for each bike and is the
key to traffic safety; before driving, you must understand your braking
system, and do a good job in the inspection and adjustment work.
The general idea is that upon hard braking, the bike will surely stop in a
short distance, but that is wrong. Upon hard braking, when the wheels are
suddenly jammed by the brake rubber, the bike will glide horizontally, and
it not only is dangerous but the braking distance will be lengthened.
Therefore, the concept should be established is that the braking system is
only used to adjust the speed of the bike.
The braking system typically includes a Brake handle, brake (disk brake, V
brake and many other types of brakes) and brake cable.
4.8.1 Brake handle
The structure of the Brake handle is
as shown (in the left drawing), and
the left Brake handle controls the
front brake and the right Brake
handle controls the rear brake.
. The adjusting screw is used to
adjust the distance between the brake pads and the Rim.
. The effective stroke of the brake cable is about a half of the distance
between the handle of the Brake handle and the grip of the Across handle
Stems; if the brake is tight when the handle of the Brake handle is almost
approaching to the grip of the Across handle Stems, the distance between
the brake pads and the Rim is too large, it needs to be adjusted.

Electric Bicycle Manual
15
4.8.2 Adjust the disc brake
Adjustment method of the brake pads:
1 Loosen the fixed screw and see there are three holes in the permanent
seat;
2 When moving the spring foot to the up hole, the elastic force increases,
so that the distance between the brake pads and the Rim is increased,
and vice versa it becomes small. Depending on the circumstances, the
braking is adjusted accordingly.
4.8.3 Brake cable
．The brake cable of the flat handle
. The bifurcation situation of the internal

Electric Bicycle Manual
16
line should be avoided, so a tail sleeve had best be covered on the line
end.
. The brake cable should be regularly taken out to be oiled, to avoid too
large resistance arisen from rust.
. The brake cable in a linear way has the best function, and if it must be
bent, the turning with a small arc should be avoided as far as possible.
. The length of the brake cable is based on the principle that it will not be
stuck when the handlebar turns left or right to the limit.
Common sense of the use of braking system：
* When the distance between the brake pads and the Rim is too large, it is
adjusted by the Brake handle or the adjusting screw on the folder gate
device.
* When the lines of the brake pads are worn seriously, replace it timely in
order to maintain traffic safety.
* When not riding for a long time, please loosen the folder device to avoid
fatigue of flexibility, but pay attention to recovery of the gate device before
riding.
* When riding in rainy days, the function of any gate device will be
weakened, so please keep a longer safe braking distance and reduce the
speed.
* The surface on the brake disc, shoe block may not be oiled, so as to
avoid serious injury.
* If the brake cable is ripped, it may cause the brake cable to be broken
and this is very dangerous, please replace timely.
4.9 Chain

Electric Bicycle Manual
17
Wear the chain and elongate it to a certain extent, it will in the chain will
climb to the chain wheel and jump, and at this time the chain has not
meshed with the chain wheel correctly, thus affecting the cycling
performance; in case of such a situation, the chain should be timely
adjusted.
Common sense of the use of speed control system：
* If the electric bike is idle for a long time, the chain will be changed to the
minimum keyboard tooth and the smallest flywheel, so as to avoid fatigue
of the mechanical flexibility.
* The chain, fluted disc, flywheel, should be always washed, wiped, and
lubricated (oiled appropriately).
4.10 Inflator （option）
A convenient inflator is hidden inside the seat post for your daily use.
Take out the seat post and then the steps to use it as below:

Electric Bicycle Manual
18
1. turn the cap from right to left
2. pull out the inflator
3. open the plastic cover
4. connect with tire valve, charge the tire as normal
5. Use and maintenance
5.1. Routine inspection of electric bike before use
1 Install the battery box in the slot of the battery box, open the power
supply switch and check whether the functions of all the electrical
appliances are normal.
2 Safety inspection (see the notes to safe use in the Manual)
3 Check whether the governor switch handle rotates and is reset flexibly.
4 Check whether the braking power-off function and braking effect are in
good condition (dry braking distance 4m, wet braking distance 15m).
5 We advise against performing maintenance operations that involve
removing parts or components. If necessary, please contact your
Authorized Dealer’s Customer Service.
WARNING:
1. As with all mechanical components, the bicycle is subjected to wear and

Electric Bicycle Manual
19
high stresses. Different materials and components may react to wear or
stress fatigue in different ways. If the design life of a component has been
exceeded, it may suddenly fail possibly causing injuries to the rider. Any
form of crack, scratches or change of coloring in highly stressed areas
indicate that the life of the component has been reached and it should be
replaced.
2. Danger of wheel failure due to rim Wear Replace wheel when any part
of the Rim Wear Groove is not visible.
