Q:I have some trouble with my electric bike again. This time the battery is okay, but hub motor is totally “dead”. The bike just stopped when I was driving. Do you have any suggestion about what to do? Is there any fuses or something else to check? All the wires are okay. Can you help me?
A:If you make sure the wires are okay. I think the problem possible comes from battery.
Case maybe when you measure the voltage of your battery,it is standard voltage,but when you need to run your wheel,the voltage will jump down less than the voltage which can drive the controller work.
You need to measure the voltage of your battery when your bike works. Not always need the motor works,just need to connect all wires and push your throttle.
See the voltage change from your battery.
Q:nothing is happening with the battery when I turn on the engine. The voltage is standing on 41 volt all the time, nothing is happening. I have opened the controller and checked the led lamps and the light is on on led 1 and in led 2 is the light blinking 6 times and then a short stop and then it´s blinking 6 times again.
So I wonder that the problem is, is it the wheel or the controller or the throttle, is there a way to test which part it is or do you have a clue? Is there any part that I need to replace with a new?
A:Could you tell me what kind of controller you use?
The problem may come from the controller.
1.Throttle
red wire and black wire: 5V
2.Hall sensor(five wires)
red wire and black wire:5V
Q:I have been doing these tests and the results is:
on number 1 (trottle)= 4.5V
and number 2 (hall sensor) = 1.2V
so it´s not the same as you have.. the battery is 41V
hoping that you can figure something out from this!
Measure the controller:
1.Disconnect five hall sensor wires from the motor
2.Measure the hall sensor(red and black) wires from controller
Hall sensor from controller(five wires)
red wire and black wire:5,13V When unplugged and 1,32V when inplugged

black wire and green wire: 5,13M Ohm
black wire and blue wire:5,12M Ohm
black wire and yellow wire:5,09M Ohm

So this means that hall sensors are broken?
What shall we do?
Is it possible to repair or change these sensors?
