"Seven countries require children to be 14 years (Estonia, France, Hungary, Italy, Latvia, Poland and Portugal)"

and this is only EU members, other non-members such as Switzerland also have 14yo minimum age for mopeds.

In addition,

"Ten Member States allow children aged 15 years to acquire a driving license for a moped (Austria, Czechia, Germany, Spain, Finland, Croatia, Lithuania, Sweden, Slovenia and Slovakia)."

which is just one year older, so I would say it's a very similar situation.
