The two wheels may be arranged in tandem, one behind the other, as with single-track vehicles, or arranged and also side by side, on the same axle. If on the same axle, the vehicle may have no other support, as with dicycles, or have additional support, which is often also the source of motive power.

Wheeled single-track vehicles include:

  • Dandy horses, velocipedes, or draisines, forerunners of bicycles
  • Bicycles, a pedal-powered two-wheeler[1]
  • Motorcycles, a motor-powered two-wheeler, similar in construction with bicycles
  • Gyrocars, a self-balancing car on two wheels

Dicycles include:
