Seems like you could probably do something with parts made for electrifying a 20" folder, transplanted to a pre-teen size frame? 24" hub motors also seem to be available.
Or would it perhaps be possible to set a folder up with suitably compact reach?
Would a tandem be an option? I believe there are things like auxiliary cranks placed higher for shorter riders
