Two beeps and the motor does not help

When the controller detects a motor hall-sensor failure, it will beep twice before
automatically entering into sensor-independent control mode. Twist/press the
throttle to run the motor and pedal your bike for a push start if the motor does not
operate. (This malfunction seldom happens in a state of sensor-independent
control status)

Just realised you have a mini motor:


Your motor may not work in sensor-less mode (without hall sensors) due to the internal freewheel device.

but I have to do to fix it?

[perdigon]

the motor only has 5 months

[Bikemad]

email Tom (zhourenli@goldenmotor.com) with details of your fault and ask for further advice.

Did your motor get very hot?
Take a look at this.

hi tom me that my engine is blown due to overload has only 4 months and everything was mounted, does not cover warranty, I'm sad customer

Hello racer, you can put a 48V battery in and it will automatically give an output of 500W. However you might burn the motor easily.

I guess I need to clarify that the mini motor can only take a max load of approximately 120kg. Any heavier than that and you go uphill, the motor is gone. Which is why some users who are big boned (over 90kg) tend to send me an e-mail telling me about how the motor wasted itself after some uphill riding. However in my honest opinion, the motors should never burn if you don't stress it too much.

 Although weight is a sensitive topic for everyone, I still have to recommend that if you're heavy, buy the 901 motor, or the Magic Pie when it comes out. I think I have to write a disclaimer on the mini motor because i've been replacing quite a number of motors for users (I don't blame them) who do not really understand the max stress load of the mini motor.

I'm surprised that it was overloaded using those small wheels, as the load on the motor is significantly reduced by using a smaller wheel.

eg:120kg load with a 26" wheel = 156kg load with a 20" wheel = 195kg load with a 16" wheel etc.
For each of these examples, the actual load (torque) on the motor would be exactly the same.

Was the total weight of you and your bike more than 120kg?

not has never exceeded 120 kg

[Bikemad]

I don't understand why your motor is not covered by the warranty, as you were running a correctly fitted 36V motor on a 36V battery, have not exceeded the maximum load limit and you were only using a 20" wheel.

Perhaps someone from GM would be kind enough to explain why this 5 month old motor is not covered by the warranty!

I am interested to know why they think your motor should not be covered by the warranty.

anyone know how to open Mini Motor say to look inside, do not see how

[perdigon]

I checked the cables connected directly and now I think it works well to see what lasts 

[Hardcore]

per,

so now it works again?
i've had cable problems aswell and these small cables seem to be not that good.

I checked the cables connected directly and now I think it works well to see what lasts 

I'm glad the motor is not burnt out and you've been able to get it going again, hopefully it will now keep going for a long time.
