I have the M600 motor on a 29er MTB. At 5000 kms the main bearing was replaced, now at 6500 the noise from the motor is embarrassing and seems failure is eminent, however it still performs well.
I would like to send a video of the noise its making….

I’m a little concerned about buying another bafang mid drive, my bbs02 died after only 6 miles. The stator & rotor was found to have overheated. I was using a greenlance 48v 17ah battery & I was riding on the flat, it was November so the ambient temperature had nothing to do with its failure. I’m a mature cyclist & fully understand the limitations of these motors, not overstretching or constant use of throttle.

I purchased a Bafang hub motor, I had to order an extension 3 pin male/female cord. This hub motor is on a Sunseeker trike. I’m getting an er 8 code. What’s wrong?

I am getting a code21H. Speed sensor malfunction. Is this simply a matter of putting in a new speed sensor? Is this a common problem?

Our motor is not working and we have a flashing wrench on the display. Any idea what might be wrong? Battery shows full.
Thanks, Jim

Bonjour,

En Mars 2023, j’ai acheté un Velo fantic Issimo Fun moteur bafang m500 mm(G250.250.C.15 033F5TB250001)d’occasion à un loueur de vélo (Go Bike 17 Ile de Ré). Celui-ci à dû changer le moteur d’origine (l’ancien étant HS). Hors, nous nous sommes aperçus dernièrement que la lumière arrière ne fonctionnait pas. Nous l’avons testé et le contrôleur délivre 3.4V au lieu de 5.8V.
5.8V étant apparemment le bon voltage puisque ma femme possédè elle aussi un vélo Fantic mais avec un moteur d’origine. D’autre part, dés que la lumière avant se met en marche, la capacité de la batterie chute.
D’après le revendeur, le problème viendrait certainement du software qui ne serait pas le bon. Malheureusement, celui-ci ne le possède pas. Nous recherchons donc le fichier CRX10NC3617i142040.6 pour remettre mon vélo à son état d’origine.
Auriez-vous ce fichier ? ou connaissez vous un revendeur ou autre qui pourrait me le communiquer afin que je puisse le transmettre à mon revendeur pour enfin avoir un vélo sorti d’usine.

Good morning,

In March 2023, I bought a used Velo fantic Issimo Fun bafang m500 mm engine (G250.250.C.15 033F5TB250001) from a bike rental company (Go Bike 17 Ile de Ré). He had to change the original engine (the old one was out of order). However, we recently noticed that the rear light was not working. We tested it and the controller delivers 3.4V instead of 5.8V.
5.8V apparently being the right voltage since my wife also has a Fantic bike but with an original motor. On the other hand, as soon as the front light turns on, the battery capacity drops.
According to the reseller, the problem certainly comes from the wrong software. Unfortunately, this one doesn’t have it. So we are looking for the file CRX10NC3617i142040.6 to return my bike to its original condition.
Do you have this file? or do you know a dealer or other who could communicate it to me so that I can pass it on to my dealer to finally have a bike from the factory.
