I'm thinking a lot of things, maybe too many to write, maybe more than is useful. I'll just say -- was this tone really necessary?
None of the posters you cite give their opinion in an effort to disrespect. You have specific knowledge about this bike, but at least one of the posters you cite sells thousands of items, bike-related and not, and is very systematic about extracting value and making a viable business.
I'm sure your advice was welcome and helpful, but the indignation is misplaced. I'll leave it there.
