Now see, this is good writing. This is how one should always write teen superheroes - as heroes, yes, heroes who kick butt, but who, being generally under driver's license age, have a few more problems than the rest of the folks in the biz. I mean, I can totally buy Steph as a character here, because she's so well delineated as a teenage girl. She argues with her mom, she writes in her diary, she fights with her boyfriend and goes home in tears, she has (major) issues with her dad, she rides her bike everywhere, and has to wheel it home when it gets a puncture - all of this is classic teenager stuff. The rest - her snarky sense of humor, her cheerful/rebellious attitude, etc. - are icing on the cake - I could have accepted her as a character without them, because it's the other stuff that makes her believable. The character details are what make her interesting as a character, but without the prosaic, riding-around-on-a-bike-crap-flat-tire stuff, she wouldn't be REAL. (I mean - you know what I mean. Real to us.)
