FWIW, Wayne, it doesn't seem to me that the two situations you describe are related. I would go ask for the bike along with a witness who is willing to testify in Court, just in case. No ifs, no buts. Just, it's taking too long and I need it back, conversation. Probably you'll get it back then. If not, go to Court. In Florida, the action is called replevin.
With regard to the other incident, just be on your toes. It is never reckless to be attentive.
