If there is a specific engineering topic that came from your question, then that could be a question here. Stack Exchange does not like the same question to be posted on multiple sites. Your question is on-topic at bicycles, so it should stay there.
As the comments have said on your question, there is a lot there. If the answer that you received did not help you, then think about how you could focus another question on the very specific question that you have. This question could be asked at either site depending on the topic.
Bottom line: Don't copy and re-post the question.
