human-powered transport

Human-powered transport is any vehicle for transport of person(s) and/or goods, powered by human muscle. Like animal-powered transport, human-powered transport has existed since time immemorial in the form of walking, running and swimming. Modern technology has allowed machines to enhance human-power. Although motorization has reduced the effort in transport, many human-powered machines remain popular for leisure or exercise and for short distance travel. Human-powered transport is often the only kind available in underdeveloped or inaccessible regions, and is considered an ideal form of sustainable transportation.
