This reminds of the days I worked in a Harley dealership. I would get very short small women in wanting to ride a full sized Harley. In some cases there are not solutions for very short people, sad but true.Short girls have it tough, lol. I would think that the companies would offer youth size mtb/hybrids though, which would be great for a 4'11" - 5'3" or so female. My wife is not a fan of the fat tire offerings that much...the ones that we have passed on the trail seem to generate a lot of tire noise from that large footprint. At least more noise that what we are used to with our comfort/cruiser type bikes.
