I wonder what is happening. I was interested in some things but do not like getting involved where there some holes in the story.
Seems you have a bank loan. Past due?
Not heard of a bank taking all the sale money unless it was sold for less than the loan amount. If you sell it, you pay off the loan and keep the rest.
Are they doing a repo?
Something going on like insurance report for stolen bike while parting it out under the table?
Hard to see how you can part out a bike with a lien on it. What about the bank loan?
Sorry to sound suspicious, but to me something doesn't seem right.
