I Think I Found My Champion

So I did more shopping around today. I went all over one side of my whole metropolitan area, and I tried out a bike called the Yorkville, by Norco. I really like it. Upright, nice step through frame, had an interesting time getting on the first time cuz I am not a graceful woman.... but I could get it adjusted and the place has that lifetime service thing that I need cuz if I know anything it's extremely basic. Until I know more I can't really expect to jump off and fix up whatever. I do need to learn how to fix a flat though. That's as far as my maintenance will go for a bit. But yeah, I'm excited. I realize the Yorkville is aluminum, but for a beginner bike I'm going to use for commuting? What do the more experienced on here think?
