If the sight of this pic....
My shins have been in fights with those dang things, usually from attempting to ride a bike made for a much taller person (average height).
There were rarely teeny tot sized bikes around so I always rode bigger bikes and that made stopping a challenge because my feet didn't reach the ground.
As long as I was going, no problem but the stopping part was an issue.
I'm not a tomboy but I have a lot of scars and dents from stuff like that because gravity happens and is cruel.
