If the ladies who are looking for a custom frame, Roberts is one good example to go for, he build a bicycle specifically for a 4'8 person;
This bike was created for a woman 4'8" tall. The seat tube, all of it, measures 13" and the wheels are 26" MTB wheels with road tyres. Note the very short stem and extra spacers underneath to raise the bars to the correct height without extending the reach too much. We don't make bikes much smaller than this very often....
