1254687 V. INSTRUCTION DESCRIPTION OF THE INVENTION (Technical Fields of the Invention) The present invention relates to a vehicle that uses two wheels arranged in a straight line to carry out and uses two feet to control the direction, especially one having two wheels. There is no manual direction controller, and there is a power pulley for people to carry, sports and leisure and table. [Previous technology] Press, currently common use of two wheels to operate The tool for traveling is two kinds of motorcycles and bicycles, and the two tools generally have a seat for the user to ride, and a handle for controlling the yaw angle of the front wheel for controlling the direction in which the car travels. It can be easily operated without any difficult skills and learning. Therefore, it is generally regarded as a kind of father and leisure tool, and for some people who are stimulating, stunts or performers, it is simple and ordinary. The transportation tools of the city will feel that there is no challenge. At present, the most common performances for performing and performing tools are to skateboard. However, the system needs to have a very good balance of effort, so there are not many people = people, however, because the general skateboards mainly use the use or special terrain (slope) to provide their driving power, so The i-series is more laborious and inconvenient, or it can only have a special terrain or a way to use it. This is the main reason why it is not universal. However, the electric scooter that is similar to electric power is now available. However, it still operates and has a structure of 2 cars. It is mainly used for seats and handles, and its simplicity is so simple that it is still not enough for those who are looking for sports stimuli.
