Three-wheeled scooter can be divided into five categories, including children's three-wheeled scooter

Ordinary scooter This kind of scooter uses the foot to periodically push the ground, giving power to the car and pushing the car forward. The original Children'S Scooter was a two-wheeled scooter, that is, one wheel at the front and the back. Later, with the further development and improvement, a three-wheeled scooter was produced. There are two models. One is the rear two wheels and the other is the front one wheel scooter. The other is a scooter with two wheels in front and one wheel behind. The three-wheeled scooters have increased stability and increased gliding pleasure, so they are more popular than ordinary two-wheeled scooters.
 It also has three wheels. The difference is that the user does not need to repeatedly drive the car forward with the pedals. The two rear wheels of this car are designed to use a universal wheel, which can swing freely and rotate 360 degrees. The user can use his feet, buttocks and legs to use his feet as long as he steps on the pedals. Left side - right side - left side - right side to do repeated movements, the car will slide forward. The dynamic car liberates the user's feet from the ground, and the use process greatly enhances the overall coordination of the athletes, and the exercise effect is more impressive.
The frog car frog car releases the user's feet from the ground like a vitality car, and the user no longer needs to pedal forward with his feet. However, the structure, function and movement principle of the frog car and the dynamic car are different. The frog car is composed of two legs parallel to the ground and a leg perpendicular to the ground, and one end of the two legs is fixed by a bearing, and the other end can be freely opened and closed. The user stands on both pedals on both feet and moves his legs to open --- --- --- ---. The frog-type vehicle has a more obvious effect on the movement of the legs, and the speed is faster than that of the revitalized vehicle. Therefore, the frog-type vehicle is more entertainment-oriented than the dynamic vehicle.
The dragon train structure is very similar to the frog car, but its movement principle is similar to that of the limousine car. Long driving speed of taxi driving is particularly high for the physical coordination of the rider and the environment of the sports venue. In the flat concrete or asphalt road, the maximum speed of the vehicle can reach 40km/h, and the eccentricity during turning is relatively high. Therefore, the driving difficulty is also relatively high. It is more popular in Europe and the United States and other countries. There are fewer domestic users.
The double-pedal scooter double treadmill is very popular in South Asia Malaysia and other countries. It was brought into China by San Carlo in 2011 and became popular in South Korea, Japan and other East Asian countries in 2013. The dual treadmill is different from the other three-wheeled scooter in terms of construction and movement principle. In this car, two vertical movement pedals are added to the rear pedal. As long as the user steps on the pedals to do upper-lower-upper-lower pressure, repeated movements can drive the car forward. Double treadmills are mainly aimed at teenagers and children. They are difficult to use, easy to grasp, and they are also good for physical fitness. They are good helpers for children's endurance and coordination. They are loved by children and are popular in some parts of the country.
