Why do gyms choose non-shock absorbing bicycles? Friends who have been to the gym know that the spinning bikes in the gym are all non-shock-absorbing bicycles, and the unit price of spinning bikes in the gym is generally high, thousands or even tens of thousands. Then why don't high-end bicycles have shock absorbers, while ordinary families have hundreds to 1000 bicycles with shock absorbers? Because shock absorption is just a gimmick to increase the selling point, customers who don't understand bicycles are easily led astray by this gimmick. Then why doesn't spinning bike need shock absorption? This is because when you exercise on a spinning bike, it is a vibration-free exercise. No vibration, no need for shock absorption. Moreover, the stability of bicycles will be affected by the addition of shock absorbers. Shock absorbers are fixed with several screws (screws are easy to rust, deform and break, which will also affect the life of bicycles), while spinning bikes without shock absorbers are fixed with steel chains. Needless to say, this stability is poor. Moreover, the shock absorber will force the human spine to move in disorder, which will hurt the spine. For example, dead flies have no shock absorption and are very comfortable to ride on smooth and flat roads; Mountain bikes have shock absorbers, which protect the spine when riding on rugged mountain roads, but riding on the road will feel very tired, which is why. Non-shock-absorbing bicycle (after many structural adjustments, the human body weight is more reasonably supported by the stable triangular structure, which is safer to use and quieter to move) Shock-absorbing bicycle (shock absorption seems to improve the sports experience, but actually increases the hidden danger of sports, and the supporting point is located in the small spring, which can not support the human body weight, so there is no sense of vibration when riding a household cycling bicycle, and there is no need for shock absorption, and the friction between the spring and the body during sports is more likely to generate noise, which affects the riding experience).
