Welcome! All I am going to say is just go out there and ride! Then when you are really into it you may want to look into getting a new bike. I know that most people will say just ride the one you have but there is really no point in upgrading the one you have.

And when you come back here to Bike Forums to post a thread it might help to use the search function as some people here can "flame" you when you don't.

Again welcome to the cycling world and have fun!
