We learn what we see

Today we saw another child with a doll-sized seat on the back of her bicycle, probably a lot like the one she rode on the back of her mom's and/or dad's bike.

We also see kids between the parent and the handlebars, like I remember doing with my dad on the way to nursery school (but without a special seat or helmet).  We see more Christiana Bikes with the kids in front, as described by David , than we see bicycle trailers.  We don't see many of the third wheel/trail-a-bikes that attach to a parent's seat post.  We do see a lot of bikes with no pedals, which is what A. used.

What a great country!
