I wouldn't get too hung up over the weight. I know, it's a common metric to compare bikes, but the EZ Sport is a decently made, nicely mannered bicycle. She's likely to put many more pleasant miles on it than she would on a much "faster" bike.
I used a EZ Rider (like an EZ Sport, but with rear suspension, disk brakes) for commuting for a winter. I grew really fond of it. So did my wife, and it became hers. It's a much more capable bike than people give it credit for (same for the EZ Sport).
So congrats, and enjoy!
