Full occupancy: 3 children in the box, 1 on the luggage rack
Two children fit on the bench seat in the box, one on the 2b3 seat opposite, and one in the back on the luggage rack in a child seat. Your child can ride in the child seat from about one to five years old.
In the front of the box, your little ones sit on a bench seat with a backrest, seat cushion, and a proper 3-point belt. This will fit from 3-4 years old well into elementary school age. However, if you install the third seat in the front, it will be tight for three school-age children. With tall children, you just have to be careful at some point that the handlebars don't hit their helmets during a sharp impact.
