Dont worry about people thinking you are or coming across as a knob, most of us are anyway so the more the merrier.

Not sure about bath but I know there is a patch club in Amesbury, one in Chepstow (Harley, I think) and you also have the Hells Angels in Trowbridge (one of our members is a member of the HA). Maybe do a search on google for mototrcycle clubs in and around Bath.
