A human-powered vehicle, often abbreviated HPV, is a vehicle propelled primarily by human muscular effort. Propulsion typically comes from the rider’s legs via pedals and a drivetrain, though some designs use arm-crank systems. HPVs exclude motorized propulsion and are used for transport, sport, and recreation. Common examples include bicycles, tricycles, handcycles, pedicabs, and cargo bikes.

Historically, human-powered transport has been widespread for centuries, with the modern bicycle emerging in the 19th century. HPVs remain popular in urban commuting for their low operating costs and zero emissions, as well as in sporting events such as road racing, mountain biking, and track cycling. In addition to land-based vehicles, human-powered craft have included pedal-powered boats and, in experimental programs, human-powered aircraft.

Design and technology vary by use but share core elements: a frame, a propulsion system connected to wheels or oar-like devices, and braking. Materials range from steel and aluminum to carbon fiber. Gear systems, where present, improve efficiency and adaptability to terrain. Cargo-focused designs emphasize payload capacity and stability, sometimes at the expense of weight or speed. Recumbent and tilting designs explore ergonomics and aerodynamics to increase efficiency.

Variants encompass upright and racing bicycles, recumbent bicycles, tandem bicycles, handcycles, pedicabs, quadricycles, and long-tail cargo bikes. Performance depends on rider fitness, terrain, and equipment. Limitations include limited speed and range compared to motorized vehicles, weather dependence, and the need for storage and maintenance.

Regulation often treats HPVs as bicycles, with requirements for lighting and safety equipment that vary by jurisdiction. Safety considerations include helmets, visibility, and sharing the road with motor vehicles.
