My wife and daughter are also "vertically challenged" and fit better on bikes with 26" wheels. My daughter's road bike has 700 wheels and on such a small frame, 700 wheels can sometimes cause pedal interference with the front wheel. Just something to keep in mind if she is OK with an MTB type bike
is one that might work. It isn't a fixed gear, just a single speed. That might actually be more user friendly less experienced riders.
The sizing chart claims the XS frame size has a stand-over of 25" which should fit her. This one does have 700 wheels.
