Lol. I have a league.
Sorry if my words made me sound like I know something for certain. I have built a few E50’s and ridden a lot of miles. Make no mistake, my response to this post was only an attempt at helpful conjecture.
A decent audio recording of the sound would be priceless in getting to the bottom of it.

What does bearing howl and small end bushing noise sound like? I have experienced wheel bearing failure in a car. It doesn’t resonate anything like the Nuge. That’s apples and oranges, but the only bearing noise I have to go on.
