Congrats on your new bici! Yep, do now whatever you feel comfortable with. The longer and more you ride, that can change, and you adjust. On going clipless, everyone I know has fallen over that way. Just come back and read about it when it happens. I teach spinning, and was an indoor rider before I re-found my love of outside. It did help w/riding clipped in the spin bici in ways. But, getting your balance while not stationary outside is another gig. Just don't get discouraged, keep trying.
