The Dutch have solved the kids/cargo problem. My friend lives in a suburb of Amsterdam. She has an electric assist bike with a cargo carrier. She uses it to carry kids and cargo, like groceries and such.
She used it to carry four kids (her three and one of mine) when we visited. We took the rented car and she beat us there.
