Human-powered land vehicle

Human-powered land vehicles are land vehicles propelled over ground by human power, The main ways to support the weight of a human-powered land vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination of the above. The main methods of using human power to propel a land vehicle are some kind of drivetrain; pushing laterally against the ground with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage opposite to the direction of travel; or by propeller. Human-powered land vehicles can be propelled by persons riding in the vehicle or by persons walking or running and not supported by the vehicle.

Many human-powered land vehicles can also be gravity-powered land vehicles, and vice versa, although some of the latter are quite awkward to use as the former. For example: street luges, gravity racers, and snow boards.

Types of ground contact
There are four main ways to support the weight of a human-powered land vehicle and its contents: rolling contact as with wheels; sliding contact as with skates, skis, or runners; intermittent contact as with stilts; and no contact at all as with anything carried. Additionally, these four methods may be combined as in wheelbarrows.

Wheeled
The most common wheeled human-powered land vehicle is the bicycle in all its forms. Other notable examples include:


 * Balance bicycles and dandy horses
 * Handcars, and draisines
 * Hotchkiss Bicycle Railroad and shweeb
 * Inline skates, roller skates, and roller skis
 * Kick scooters, kickbikes, knee scooters, and square scooters
 * Rickshaws, prams, strollers, roller buggies and buggies/Shopping trolley (caddy)
 * Skateboards, longboards, Penny boards, snakeboards, caster boards, Freeline skates, Surfskate (or Carveboard)
 * Tricycles, quadracycles, and velomobiles
 * Trikkes
 * Unicycles
 * Wheelchairs and baby walkers
 * Heel Skates

Sliding

 * Skis, snowboard, snowskate
 * Sleds
 * Ice skates and clap skates
 * Mud horses and mud sledges

Intermittent

 * Stilts
 * Powerbocking
 * Pogo stick

Types of propulsion
There are three main methods of using human power to propel a land vehicle: some kind of drivetrain that turns one or more drive wheels; pushing laterally against the ground, to the side relative to the forward motion of the vehicle, with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage, such as a hand or a foot, opposite to the direction of travel, or by pushing against the air with a propeller.

Lateral motion of one or more wheels, skis, or skates

 * Ice skating
 * Skate skiing
 * Inline skating and double push

Direct contact with the ground

 * Skateboarding
 * Kicksleding
 * Poling
