All I hope for is someone to Recognize the Sound, to identify the sound, its origin, its cause. I wouldn’t be here if I had not already talked to bike shops and the company, presented them with audio, and did a very thorough search of YouTube. So far, no one is saying “I know that sound!” which is to me, incredible. I cannot be the only person to have ever heard this noise on an Ebike with disc brakes. I have heard solutions of ‘water in the pipes‘ (it’s not), align the pads (they are aligned) or simply ‘return it‘. It’s all guesswork so far. So I’m hoping someone here knows more than the company itself or a professional Ebike repair shop. I don’t know where else I can go for answers. All I can hope for is that I can get a refund if problem is not solved.
