Yes, the GV250 should be good for a small person. I am about 5'4" and 125 lbs, and an over 60 female.
I have no problem with the scooter in street situations. My feet are almost flat footed.
Only problems arise when riding over the back yard to park my scooter.
The yard is not smooth, so my progress is jerky, but without mishap.
It sounds like a good purchase. I've only 3k miles on mine, all without any problems.
scoot safely,
