Welcome to the 250 club!! It's the best, but I may be a bit biased
I'm 5'3" and it can be a bit nerve wracking at first to not have both feet planted firmly. Ride, ride, ride and you won't even notice it after a while. Best thing I do to up my confidence in that arena is to practice in a small parking lot. Stops, turns, figure eights, and circles. Really helps get clutch down and the confidence.
