The first freight bicycles were used by tradesmen to deliver mail, bread and milk amongst other things. Early freight bicycles were heavy-duty standard bicycles, with heavy carriers at front or rear, sometimes with a smaller front wheel to accommodate a large front carrier. During the early part of the 20th Century these were commonly used by tradespeople for local deliveries. In the UK this style is still sometimes known as a butcher's bike or delibike, although the Post Office have by far the largest fleet; a more formal name is porteur bicycle.
With the domination of the internal combustion engine in the industrialized countries after World War II, freight bikes became less popular. In the rest of the world, however, they continued to be manufactured and heavily used. In the 1980s in Europe, and the 1990s in the US, ecologically-minded designers and small-scale manufacturers initiated a revival of the freight bike manufacturing sector.
