5. GENERAL TECHNICAL INFO

TROUBLE SHOOTING:
Q. Why won't my Electronic Vehicle turn on? There is no lights or power when I turn the key
switch?
•
Check the main power switch also known as circuit breaker or main breaker.
•
Make sure the power wires are securely tightened inside the main power breaker switch.
•
Make sure all your battery wires are tightly connected and all power connections are not loose or
not attached.
Q. My lights work but my Electronic Vehicle will not move?
•
Make sure it is charged. If it is not, once voltage reaches a low level the controller will not turn on
and as a result the bike will not move even if the low voltage can power the lights. For example, a
48v battery will go down to 42v and it is considered empty because the controller turns off to
protect the batteries from low voltage. It is also known as an LVC which is an acronym for Low
Voltage Cut Off.
•
Check the brake handle switch wire as it could activate the motor cut off if not fully released.
•
Check all connections of the only 3 other parts that would cause this. They are the throttle,
controller or motor. It is rare that the motor has any issues because it is the most robust
component of the vehicle. However, there are hall sensors inside the motor that could go bad
•
on rare occasion. A remedy for this is using a sensor less controller. It may be a better alternative
to replacing the hall sensor or motor completely.
**To recap, this issue can be due to a number of reasons, but we will start with the most likely
and simple fix.
1.
The brake switch is stuck on. Check your rear red tail stop light to see if the light is activated by your brakes.
2.
The kill switch or kickstand switch (if equipped) is stuck on.
3.
The controller needs to be replaced.
4.
The throttle wire has a loose connection or needs to be replaced.
5.
It is not common to be a motor issue because it is typically the most robust electrical component on the
vehicle.
Q. The battery voltage/gauge/meter drops when I ride. Why does it do that?
•
As you draw power from the battery you will get some voltage drop that will settle once you stop.
It is recommended that you charge the E-bike as frequently as possible to maintain battery capacity
for both speed and range. As your voltage is depleted the Electronic Vehicle speed will lower
incrementally.
•
The sudden shut down is called low voltage cut off. The controller will shut down to protect the
battery if level is too low. It is the drain of power from a stop or up hills that will bring down the
voltage down. It is called voltage drop when you draw power. Charge the e-bike more in this case.
