You can bring everyone along with this trike (kids, friends, family pets, grandparents, etc.). Made in the Netherlands (of course), the DeRedding KDV fits up to 8 children on its tandem benches with a protection bar for each bench (like an amusement park ride, more convenient than individual seat belts).

These are often used instead of a bus by many schools and day care centers in Holland. Available worldwide, though not cheap at €2950,-
