10. Maintaining the power-off control of the brake lever*
This is a very important component for riding with safety. First, you should pay attention
to protect it from impact and avoid any damage. Second, make regular check on all bolts
and nuts, and fasten them securely.
11. Simple trouble shooting
The information below is for purpose of explanation, not as a recommendation for user
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 “pow-
er 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 con-
nection 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 se-
curely fixed. If loose, joint them
tightly. 2) make the brake lever
come back to its normal posi-
tion 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 install-
ing a new fuse; 4) adjusting the
distance between the magnet-
ic ring and the sensor, to make
sure the distance is within 3mm;
5) fix tight the connection be-
tween the sensor and the con-
troller.
The distance per charge be-
comes short (Note: perfor-
mance 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 tempera-
ture 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 tires 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 ac-
cording the instruction (chapter
7.3); 2) in winter or under 0°C,
you’d better store the battery in-
side the house; 3) it will be nor-
mal if the riding conditions are
improved as regular; 4) pump
the tires and ensure tires are ful-
ly 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 ac-
cording to this instruction man-
ual (refer to Chapter 6.3) If the
above has no effect, please con-
tact your vendor or authorized
service.
