Boneshaker is a name used from about 1869 up to the present time, to refer to the first type of true bicycle with pedals, which was called "velocipede" (from the Latin for "fast foot") by its manufacturers. "Boneshaker" refers to the extremely uncomfortable ride, which was caused by the stiff wrought-iron frame and wooden wheels surrounded by tires made of iron.

"One end of the cup-adjusting hub, with inward bearings. The cones are formed of one piece with the spindles, and the adjusting cp C is screwed in the end of the hub shell, and locked in position by the screwed locking-ring R. The figure also illustrates a divided spindle for facilitating the removal of the tire for repair when required without disturbing the wheel, bearings, chain or gear-case. The chain side of the hub-spindle, not shown in the figure, is secured to the frame in the usual way; on the left side the spindle S projects very little beyond the adjusting cup. A distance washer W is placed between the end of the spindle S and the fork-end F. A detachable screw-pin, or the footstep, P, passes through the washer W, and is screwed into the end of the spindle S, the hexagod head of the detachable pin drawing all the parts securely together." — The Encyclopedia Britannica, 1910

A hobby horse (or hobby-horse) is a child's toy horse, particularly popular during the days before cars. Just as children today imitate adults driving cars, so, in former times, children played at riding a wooden hobby-horse made of a straight stick with a small horse's head (of wood or stuffed fabric), and perhaps reins, attached to one end. The bottom end of the stick sometimes had a small wheel or wheels attached.

A tracked vehicle is a vehicle that runs on continuous tracks instead of wheels. The principal design advantages of tracked over wheeled vehicles are that they are in contact with a larger surface area than would generally be the case with a wheeled vehicle, and as a result exert a much lower force per unit area on the ground being traversed than a conventional wheeled vehicle of the same weight.

Velocipedes are an umbrella term for any human-powered land vehicle with one or more wheels. The most common type of velocipede today is the bicycle. The term velocipede is today, however, mainly used as a collective term for the different forerunners of the monowheel, the bicycle, the dicycle, the tricycle and the quadcycle that were developed between 1817 and 1880.
