A two-wheeler is a vehicle that runs on two wheels. These include, but are not limited to:
- A dandy horse, velocipede, or draisine, forerunner of the bicycle
- A bicycle, a pedal-powered two-wheeler
- A cab or hansom on two wheels
- A motorcycle, a motor-powered two-wheeler, similar in construction with bicycles
- Dicycles in general, including self-balancing personal transporters
- A hand truck, a two-wheeled device used for transporting bulky or heavy items such as furniture or golf clubs
A dicycle (also known as a diwheel) is a vehicle with two parallel wheels, side by side, unlike single-track vehicles such as motorcycles and bicycles, which have inline wheels. Originally used to refer to devices with large wheels and pedals, the term is now used in relation to powered self-balancing scooters with smaller wheels and no pedals such as the Segway PT and the self-balancing hoverboard.
In more recent usage, a dicycle including both pedaled and motorised vehicles with wheels of varying sizes. Merriam-Webster dictionary however, limits usage to 'velocipedes with two parallel wheels' and the Oxford English Dictionary to 'pedal-powered vehicles with large wheels placed parallel to each other'.
