The unicycle uses the lever principle to close the resistance point of the load to the fulcrum (i.e., the wheel) to make its operation efficient, and also shares the load on the unicycle and the operator. Because unicycle makes it easy to move heavy or large loads, it is indispensable in construction sites, agricultural land and gardens.

Although the two wheeled handcart is relatively stable on the flat ground, the unicycle has high operability in places prone to imbalance, such as small, planked or raised roads, and is easier to control when unloading.

In the past, unicycle wheels were made of wood, ranging from large to small. The smaller one is flat; The larger one is higher than the wheel, and the wheel is divided into left and right sides, which can be used to carry objects or sit people, but both sides must be balanced. Between the two handlebars, hang a "car trip". When driving, put it on the shoulder and hold the handlebars with both hands to help. Generally, a unicycle is pushed forward by one person, but there are also large unicycles for carrying things. There are two handlebars at the front and back, which are called "second handlebars".
