Yes, technically there is a way... given it is street-legal in your country to have a child riding along with you.
There's a special child-seat for motor/electric scooters available: The Stamatakis Maxi seat is especially made for scooters and motorcycles and perfectly fits the N1s saddle.
4 loops are used to fixate the seat to the saddle: One below the saddle itself, one around the front of the seat-compartment and two can be looped through the handlebars in the back.

My daughter (aged 6) is just able to reach the foot-rests. Smaller children can use the supplied foot-slings which come with the Stamatakis.
