Welcome to the sometimes confusing world of women specific cycling! Lots of great brands out there and YES you do need to make the tour to different shops.

You'll not only be buying a new bike, but you should also base purchase and relationship with shop (you never know when you'll need their help)..

Again lots of brands entering womens market but you probably find SPECIALIZED to have one of the widest cross sections of womens bikes.

Looking for a commuter bike- give the Globe a try--next best thing to car ( lights, rack sturdy, step through). They also have a good selection of entry road bikes too. Welcome- Good luck- be safe!
