Cargo Bikes - What Can't You Carry or Haul?

PROPERLY EQUIPPED, A BICYCLE CAN BE REMARKABLY UTILITARIAN

I've never heard of cargo bikes before. I've seen people riding bicycles with baskets that they can put a bag of groceries in, or a bunch of flowers, or pulling a child behind in a colorful weatherproof 'capsule'. But the idea of being able to accomplish most of your errands, including hauling a boat (if you have one), wall paneling, or whatever, never crossed my mind.
