Hello every one here is the problem . I had a m600 bafang won t turn on .

The bike was under warranty so i got a new motor .

With the new motor the bike start with the old one no .
So i decided to change the controler and no the bike won t start even after i change the controler .

So what the next step to check on the motor and what should i change ?

Anyone have a video how to replace the cable interface inside the engine please ?
Thank you to everyone .

Hi @boom boom ,
The reason why the controller won't turn on is because you need to calibrate the controller to the motor via the besst tool.
Seb G walks you through the process in his video.

Let me know if you need help sourcing the besst tool and getting an account with Bafang

Good morning!! I have a 4LEAF bike with Bafang M600 and DP C18 CAN display. The problem started with difficulty turning on the bike. Sometimes I had to remove and replace the battery until it stopped turning on.
The battery was tested on another bike and it was ok. I bought the Besst tool and a new controller but the Besst tool does not connect to the controller. Neither the new one nor the old one. I read on another forum that to calibrate or update it is necessary for the Besst tool to read the controller information, such as the serial number. Can anyone give me a tip?
