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 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 LED 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 LED 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
