Same exact issue , same noise ,I've had the bike for less than two months. The only silver lining ( If I can call it that ) is I now I realize I'm not the only one with this same exact issue. I gone through the whole send us video and try this and then try that to be told that they would get me a new bike frame. This was to happen this week , but when they called to say they were around the corner they told me they did not have the new frame. they were just picking up the bike. Needless to say I lost it on them. After speaking with customer support they told me they had no idea why this happened and they would get back to me within 24 to 48hrs. So I guess I won't find out until next seeing that were heading into the weekend. I took it up with the CEO, now I'll just have to wait and see if Peloton really values existing customers.
