Spanish tutor / bike riding / dancing partner (New York)

Folks, I'm looking for a Spanish tutor / offering my English or Thai tutoring in exchange.
Separately, I'm looking for a casual biking buddy (I have a folding bike).
And also separately a dancing partner (I'm a beginner but I have some rhythm and I am willing and eager to improve. I'd like to learn all kinds of dancing).
But if you fit all three, I won't turn you down either =)
