Velomobile in the context of "Aerodynamics"

A vehicle (from Latin vehiculum) is a machine designed for self-propulsion, usually to transport people, cargo, or both. The term "vehicle" typically refers to ground transport vehicles such as human-powered land vehicles (e.g. bicycles, tricycles, velomobiles), animal-powered transports (e.g. horse-drawn carriages/wagons, ox carts, dog sleds), motor vehicles (e.g. motorcycles, cars, trucks, buses, mobility scooters) and railed vehicles (trains, trams and monorails), but more broadly also includes cable transport (cable cars and elevators), watercraft (ships, boats and underwater vehicles), amphibious vehicles (e.g. screw-propelled vehicles, hovercraft, seaplanes), aircraft (airplanes, helicopters, gliders and aerostats) and space vehicles (spacecraft, spaceplanes and launch vehicles).

This article primarily concerns the more ubiquitous land vehicles, which can be broadly classified by the type of contact interface with the ground: wheels, tracks, rails or skis, as well as the non-contact technologies such as maglev. ISO 3833-1977 is the international standard for road vehicle types, terms and definitions.

A nose cone is the conically shaped forwardmost section of a rocket, guided missile or aircraft, designed to modulate oncoming airflow behaviors and minimize aerodynamic drag. Nose cones are also designed for submerged watercraft such as submarines, submersibles and torpedoes, and in high-speed land vehicles such as rocket cars and velomobiles.

A bicycle fairing also called recumbent fairing is a full or partial covering for a bicycle to reduce aerodynamic drag or to protect the rider from the elements. It is more common to see recumbent bicycles with partial or full fairing. A bicycle with a full fairing is a regular bicycle fitted with an extra component, as opposed to a velomobile, which is a permanently enclosed bicycle.

The term micromobility refers to a category of small, lightweight vehicles designed for short-distance travel in urban areas and operated by their users. Micromobility encompasses a wide range of transport options, including bicycles, velomobiles, e-bikes, cargo bikes, electric scooters, electric skateboards, shared bicycle fleets, and electric pedal-assisted (pedelec) bicycles. Motorized micromobility vehicles are also known as personal transporters.

Initial definitions set the primary condition for inclusion in the category of micromobility to be a gross vehicle weight of less than 500 kilograms (1,100 lb). However, according to a standard of the SAE International in 2018 the definition has evolved to exclude devices with internal combustion engines and those with top speeds above 45 kilometres per hour (28 mph).
