A tricycle is a one-wheel vehicle used for walking, cycling or driving.
There are different types of tricycles available: electric, hybrid, manual and rotary.
All tricyclists can have different types and sizes, and some tricycling has been seen in urban areas in recent years.

Some countries such as Germany and Italy have introduced regulations to limit its use.
In Ireland, tricycled cars are now banned from public roads, although they are still allowed in the back of some private properties.
The country’s Transport Minister Leo Varadkar has said that he does not want to “kill the bicycle” in the country.
He has proposed a bill to make it easier for tricycared vehicles to get through Dublin City Councils traffic lights and pavements.
“We want to give people the choice to cycle in a bike lane, so they can get from point A to point B without having to change lanes,” he said in January.
In April, a tricylist was killed after she was hit by a truck in County Clare, and in December a woman was killed by a driver who failed to stop at a red light.
Ireland has more than 200 tricybridges, many of which are equipped with cameras and GPS systems.
