Have you bought the bike Rock? Sounds like something you're really interested in for you. I say go for it!!
I'm just back from pantomime rehearsals (not sure if panto is a british thing?). I am the least theatrical person you could come across. I'm very self conscious & very self critical but wanted to push myself in my GAL activity goal of improving confidence. I absolutely love it now. Not the acting (I still hate that) but the local community people are all amazing and it really is so funny doing it & I've met a bunch of amazing people.
Put your reservations and thoughts to one side & push yourself to do something just for you. Not for W or S. Just for you.
