All of the types of bikes listed on the "Men Cycles" page, road bike/ flat bar/ hybrid/ mountain bike are available in ladies frames.

These are two types of ladies frames:

Traditional ladies design with the top tube lowered and low step through -  to allow ladies to ride wearing a skirt.

New WSD (Womens Specific Design)
Some more consciencious women riders would buy gents frames, because the triangulated design of the main frame is more efficient. However because women tend to bend from the waist and not the hips, the reach to the bars was too long.

Maintaining this position led to a sore neck and back.

The WSD is built on a shorter frame and higher front - completely redesigned, not just a gents frame sprayed pink.
