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:

























= 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.
