I can understand how she feels six years ago I replaced my fifteen year old 10 speed mountain bike. The bike I eventually bought, a 21 speed hybrid bike, was something of an adjustment. 21 speeds, quick release rims and seat, with a flat bar. It was quite the change in technology. It sounds like Ms. Scottoline is riding a similar bike.
In her article she talks about how the flat bars are a change from cruiser bars and how she can't figure out how to adjust the seat and handle bar height which makes riding the bike rather uncomfortable. My advice to her is either go to the bike shop it was bought at or a local bike shop and have them fit the seat height and handle bar height. They can also provide you with better options for saddles designed for women and may be able to change the handle bars to something you may be more comfortable with.
A common mistake for many new cyclists is being to nervous to admit that they are not sure how to do a basic adjustment on their bike, so riding it becomes uncomfortable. Which eventually leads to the bike gathering dust in a basement or garage. Your local bike shop is always willing to help you make basic adjustments to handlebar and seat heights. If your bike has a quick release front wheel have them teach you how to take it on and off. This will help you be able to transport your bike in a car when you don't have a rack.
A new bike does not have to be a scary piece if technology, take the time to have your local bike shop teach you how to use your bike and enjoy the ride.
