Human-powered vehicles (HPVs) are modes of transportation that rely on human effort for propulsion. Common examples include bicycles, tricycles, and pedicabs. These vehicles convert the energy generated by pedaling or other physical movements into motion, making them an eco-friendly alternative to motorized transport. HPVs can vary in design and purpose, ranging from recreational bikes to specialized vehicles like recumbent bicycles and handcycles. They are often used for commuting, exercise, and leisure, promoting a healthier lifestyle while reducing carbon emissions and traffic congestion.
