It is not a good experience to have your child's foot jammed in the rear wheel.
I know this as well because the same happened to my 5yer old daughter on the first trip with my new Mundo last weekend.
No really damage to the foot, but we did ride to the hospital for a check.
where did you purchase your wheel skirts?
