Danger.Its shortcoming mainly includes：1st, driving technology is complicated, is not easy to grasp, and needs to carry out prolonged professional training could to slap
It holds；2nd, using (or semi-crouch) posture of standing of leaning to one side, center of gravity is higher, and driver needs constantly twisting body, alters one's posture, balance is not
It is easy to control, easily fall down；3rd, driver foot is fixed on slide plate using the fixator that cannot be automatically disengaged, such as fallen accidentally
, for driver when rolling on snowfield, slide plate easily sprains driver leg；4th, power source is slided from slider's body
Torsion fortune, fully rely on lower limbs strength, knee joint bears body gravity and buffers since ground convex-concave is rushed to what body was brought
It hits, this leads to lower limb, and because persistent movement easily generates fatigue, knee tissue damage is bigger, and physical demands is than very fast；5th, cannot
More people drive single skis or slide plate simultaneously.
