My experiency of bafang failure repair. I'm not going to tell all the history, too long and conditions have changed since the begening. I will speak only of the last procedure.
If you have an failure with the bafang motor the first step is to check visualy the conectors and the wiring: No damaged contact ? all connectors well pressed ?
After you can check if the power supply arrive correctly on the motor connector: +-51Vdc when the power switch on frame is pressed, +-45 Vdc when it is unpressed
If all these point is well and the display do not light up when you maintain pressed several seconds (+- 5) the power switch on the remote, you can init an bafang after sale request.
You need to ask to the motor supplier they initiate an repair request to bafang. they will transmit you an formulary "Warranty Request Bafang Blank 2021;xls" with the adress of the bafang ervice center most near your country. you fill it, return it to the bafang after sale service and you sent your motor or the electronic parts if you have competencies to dismantel (the controler, the motor connectors printed circuit, the wirings (internal frame cable, dispaly, remote).
At this time i did not find where i can purchase spare parts for M500. luna in US seem to store for M600, but shipping cost/administrative fees/taxs are very expensive to the europe.
Bafang do not make any difficult to applied the waranty, but they do not want to treat with the customer, they wait that the supplier perform the request.
It was difficult with dengfu, for who the word "warranty" seem to block the answers ? But it seem they have evoluate on this subject. May be it is better to request only "bafang repair procedure" and don't mention the bad word, In any case it is bafang who decide if the failure is under warranty or not.
Personally, my electronics parts are currently in transit to the bafang service center in poland.
