What is the design principle of electric scooters?

There are many types and names of electric scooters. The principle of "two-wheeled scooters" is used here.

The "two-wheeled skateboard" is also called "two-wheeled skateboard" and is a new kind of skateboard, also called "land surfboard". Unlike ordinary four-wheeled skateboards, it only has two wheels. Because it moves like a dragon and a snake, it is also called the "Swimming Dragon Skateboard", "Kinetic Board", "Snake Plate", and so on.

When the wheel of a two-wheeled scooter is deflected by a certain angle, it will deflect in a direction with the least force, that is, side-to-front or side-to-side movement, so it is meandering (the s-shaped movement path). This is the use of the correctness of the front wheel of the scooter. The twisting of the human body produces torque, and the use of skills, can convert part of the human twist energy into kinetic energy, so that the two-wheeled scooters move forward (normal four-wheeled scooters go straight, relying mainly on the back of the human leg to provide energy ). Unlike ordinary four-wheeled skateboards, players can only use the waist, buttocks and the twisting of their feet, and the swing of their hands to drive the vitality board. The s-line travel also plays a role in balance. This is not like the bicycle handlebars to adjust the direction and balance (the two-wheeled scooters also have the type of handle to help adjust balance), so they can only be coordinated with the movement of the body.

The driving force behind the vitality plate comes from the static friction between the wheel and the ground. The structure of the wheel determines that as long as the wheel rotates through an angle β around the axis of rotation, the horizontal frictional force f between the wheel and the ground drives the vigor board along the horizontal component of the direction of motion. Therefore, on a smooth road surface, static friction does not exist and the vibratory plate cannot advance. In doing this exercise, the operator's feet are constantly oscillating back and forth on the plate surface in order to keep the angle β always present, ie the angle β must be maintained by external forces.
