Hmmmm... Film cameras with automatic advancing mechanisms are/were "motorized" too.
I think the motorized rules were meant to apply to gasoline-powered machines (think chain saws, motor bikes, generators, etc), not small battery powered equipment.
I can't speak for the parks (George?), but in national forests, wheelbarrows are prohibited under the rule.
