I checked. Everything is OK. I contacted the seller and he informed me that he was sending me another battery. I don't understand why I can't find information about the controller that it would be 500 W. Everywhere I find information that mentions that the controller works for 350 w. Is that normal? Can I replace the controller with a 500 w?
For a while the bike worked perfectly, but suddenly it stopped instantly. It didn't start from the M button until after I turned the key in the ignition and then I pressed the M button. I walked for a while and then more and more often this defect appeared to me. I wrote on the seller's website and he informed me that it would be a battery problem ...
