The main differences between land surfboards p7 and s7 are:
Surfboard S7: The bridge has a built-in spring structure, which can freely adjust the movement. It is relatively easy and labor-saving, and is suitable for advanced surfing trainers. The bends are quicker and easier. There are more secure nut symmetrical spring designs.
Surfboard P7: It has anti-rust accessories, double-cone PU on the front axle, and increases the steering angle. You can gain forward acceleration without pushing off the ground, and you can push forward just by moving your center of gravity.
Land surfboards fundamentally change the concept of traditional skateboards. They do not need to step on the ground, but rely on left and right pressure boards to provide forward momentum for gliding. The important thing is that the steering angle provided by the bracket is large, which can well simulate the feeling of sea surfing.
