here is my wifes XS Troll, with trekking or butterfly bars. I looked at my gearing charts, and with 1.5in tires, the stock 48/36/26 with ten speed 11-36 gives 18-108 gear inches, an excellent good range as is. Again, if you are going to be offroad, perhaps a mtb triple would be better, but the 36t mid ring is a great all rounder chainring along with the 26, which by the way, its super easy to put down to a 22t on the granny position of deore triple cranksets., or a 24 or whatever.
The rear rack is what I had kicking around, but a shorter one would be nicer to put the panniers down lower, but didnt realize the issue that occured because its a xs small, this rack was fine on my med troll when I bought it, rack came with my bike.
As you can see, the uncut stem makes it easy to have bars at a nice high position, which is really going to help with neck and hand issues for someone less flexible, and just a more comfortable ride if someone isnt a strong rider. The odd looking angle of seat works well for my wife, but as the bars are so high, the angle works fine for her, along with the peculiarities of brooks seats sometimes being better slightly tilted up if your bars are higher. My brooks are all flat and work better that way.
My wife is about 5'1", maybe 5ft only actually.
