How do you stop gracefully when your dumpy little leggies only just reach the ground??!---timetotstart.
I’m going to go out on a limb here and speculate that you are not dismounting your saddle/seat when you stop. Most bikes, not all, but most; when you have the saddle adjusted to the correct height, for proper leg comfort; you will not be able to touch the ground with your feet when you are at a standstill, and setting on the saddle.
My wife had the same problem, until I explained to her that she needed to support herself on one pedal {either right or left, whichever feels more comfortable) and slide forward and off the saddle when coming to a stop. Put the free leg on the ground as you come to a stop, and then bring the other foot to the ground and stand straddling the center bar of the bike; still holding the handlebars to keep the bike from tipping over… it really is more complex to try and explain it in words, than to do it in practice…
My wife doesn’t like to hop on and off the seat when we come to a stop, and take off again, but she finds it more practical than falling over…

and has found her legs feel much better and she enjoys riding more with her seat set at the proper height… hope this helps you out some.
