Rear wheel making a rattling noise

[griefter77]

The screws are in spiggot , so it won't be them that's causing the problem. if only you guys would give us information in the first place, it would save a lot of time and effort. What about answering the other questions I asked.

Undo the two brake caliper screws and lift off the caliper. See if the noise goes away. Also check that the disc screw heads aren't touching anything.

The noise just starts randomly one day. It wasnt there when it was new, it started at around 70 miles. Not sure what changed, everything was fine until it starts to make that horrible noise. I have been riding it daily for almost a week plus since the noise started and its still there. I noticed that there might be a slightly more vibration when riding but might be just placebo.

This is the full email the manufacturer sent

my colleague forwarded me your message and video regarding your recently purchased Kommoda. It would appear there's an imbalance in the motor that is causing vibration, giving the noise and movement you're experiencing. This could be a small fix or may require a complete motor. I can send you out the relevant parts if you feel confident making the repairs (or have a mechanic locally who you trust), or we can look to getting the wheel back here so I can fix it myself. Let me know how you'd prefer to resolve this.

First you should eliminate anything that could be caused by your installation. In 13 years of dealing with hub-motors, I never heard of one being out of balance.. I've seen one before where a screw came out and was rubbing on stuff in the motor. the only other thing I've seen causing noise apart from rust was a dislodged magnet. There are two posibilities for that: The speed sensor ones often fall off, but don't normally cause any problems; and the motor magnets can cum unstuck, but the internal motor runs much faster than the wheel, so it's a much faster sound. Yours sounds like something touching at wheel speed.

Have a good look and make sure nothing is touching the disc on its edge or outside face.

A long shot - in both vids with the wheel spinning the chain and sprockets are stationary so you'd normal expect to hear the free-hub ratchet mechanism 'clicking' - might that aweful noise be a faulty freehub?

Does the noise stop when you actually pedal or is it only there when free-wheeling?
