6. Using and Maintaining the Battery.:

Advantages of Li-ion battery. This electric assistance bicycles are supplied with high quality Li-ion batteries,

which are light and create no pollution to the environment, as a typical green energy source. As well as the
above features, the Li-ion batteries have the following advantages:

• charging without memory effect

• big electric energy capacity, small volume, light in weight, with large current output, suitable for high

power vehicles.

• long life

• a wide working range of temperature: -10°C to +40°C

To ensure a longer battery life and protecting it from damage, please use and maintain it according to the
guideline below:

15/61

6.1 During your riding, when you find the power decreased

to one segment on the LCD. (See the Fig 16) , the battery must

11. Simple trouble shooting.

The information below is for purpose of explanation, not as a recommendation for users to carry out repair.

Any remedy outlined must be carried out by a competent person who is aware of the safety issues and
sufficiently familiar with electrical maintenance.

Trouble Description

Possible Causes

Trouble shooting

After the main battery
switched on, the motor
does not generate
assistance when pedaling.

1)the motor cable (waterproof
connection joint) is loose; 2) brake
lever did not return well, which keeps
the switch in “power off” position; 3)
battery fuse is broken; 4) the speed
sensor
is too far away from the magnetic ring
on the B.B.axle; 5) the connection
between the sensor and the
controller is loosen or not connected
well.

First of all, please check the battery if it is
empty. If yes, charge the battery immediately. 1)
check if the connection is securely fixed. If
loose, joint them tightly. 2) make the brake lever
come back to its normal position with care,
without braking; 3) open the battery pack top,
and check if the fuse is broken. If yes, please
visit your vendor or authorized service for
installing a new fuse; 4) adjusting the distance
between the magnetic ring and the sensor, to
make sure the distance is within 3mm; 5) fix
tight the connection between the sensor and
the controller.

The distance per charge
becomes short (Note:
performance of the bike
battery is directly related
to weight of the rider and
any baggage/load / wind
/ road / constant
braking ).

1) charging time is not enough; 2) the
environment temperature is so low
that it affects the battery working. 3)
frequently going uphill, or riding with
head wind, or on poor road condition,

4) the tyres have low pressure (to be
inflated); 5) frequently braking and
starting. 6) battery has been stored
without using for quite a long time.

1) please charge the battery according the
instruction (chapter 7.3); 2) in winter or under

0°C, you’d better store the battery inside the

house; 3) it will be normal if the riding
conditions are improved as regular; 4) pump the
tyres and ensure tyres are fully inflated to 45psi
for your bike; 5) it becomes normal when the
riding situation will be better. No worry about
such a trouble; 6) make regular charging

18/61

according to this instruction manual (refer to
Chapter 6.3) If the above has no effect, please
contact your vendor or authorized service.

After plugging the power
outlet, no charger
indicator LCD is lit.

1) trouble from the power outlet;

2) poor contact between charger input
plug and power outlet;

3) the temperature is too low.

1) check and repair the power outlet.

2) check and insert the power outlet tightly. 3)
charge it in house.
If the above has no effect, please contact your
vendor or authorized service

After charging over 4-5
hours, the charger
indicator LCD is still red,
while the battery is still
above not full (Note: it is
very important to charge
your bike strictly
according to this
instruction stated in
Chapter 7, to avoid any
trouble and damage
occurred to your bike.

1) environment temperature is 40°C
and above.

2) environment temperature is under
0°C.

3) failed to charge bike after riding,
resulting in over discharge.

4) the output voltage is too low to
charge the battery.

1) charge the battery in an area under 40°C, or
according to this instruction chapter 7;

2). charge the battery inside the house, or
according to this instruction chapter 7;

3) please well maintain the battery according to
the Chapter 6.3 to avoid natural over-discharge;

4) no charging when the power supply is lower
than 100V.
If the above has no effect, please contact your
vendor or authorized service.

There is no speed/KM
show on the LCD

The magnetic ball point on the wheel
spoke is in too far away distance from
the wheel speed sensor (fixed to frame
chain stay or front fork), which make
the sensor cannot get any signals of
the revolving wheel.

Check the distance between the magnetic ball
point and the wheel speed sensor, and make
sure the distance should within 5mm.
