|Tricycle plus wheelbarrow. It might work.
This photo is a scanned family slide from a about the 1960s. I think the child is my husband's younger sister Kay. I like the creative thinking of the children at play. It looks like the arrangement of tricycle towing a wheelbarrow complete with passenger would work. And obviously an adult has taken the photo so they couldn't have been too worried about consequences.
