I think deep down they are intimidated by you. I work in a unit of guys and yeah always get picked on. Although I can dish it out when I need to. They tease the ones they like. If they completely ignored you then I'd worry. You are a threat to the machoness of the boys bike club. Since you've been invtited to the velo it sounds like your in, just don't take the crap. If someone says something you don't like, give it right back. Remind them when they get too cocky that they are not perfect. Have fun with them. It's cool to be independent and different, enjoy it.
