important to charge your bike
strictly according to this instruc-
tion stated in Chapter 7, to avoid
any trouble and damage oc-
curred to your bike.
There is no speed/KM show on
the LED
44/76
Causes Possibles
1) trouble from the power outlet;
2) poor contact between char-
ger input plug and power outlet;
3) the temperature is too low.
1) environment temperature is
40°C and above.
2) environment temperature is
under 0°C.
3) failed to charge bike after rid-
ing, resulting in over discharge.
4) the output voltage is too low
to charge the battery.
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.
Résolution

outlet.
2) check and insert the pow-
er outlet tightly. 3) charge it in
house. If the above has no ef-
fect, please contact your ven-
dor or authorized service.
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

tain the battery according to
the Chapter 6.3 to avoid natural
over-discharge; 4) no charging

effect, please contact your ven-
dor or authorized service.
Check the distance between
the magnetic ball point and the
