[0002] Bicycles are commonplace in our lives. However, with social development, people are becoming more aware of physical exercise, and therefore have higher requirements for the function of bicycles and the places where they can be used. Ordinary bicycles can be used as a means of transportation or fitness equipment, but long-term cycling for exercise can compress the prostate and may increase the risk of prostate disease.

[0003] Elliptical trainers are a common and popular tool for cardiovascular fitness training. The biggest advantage of elliptical trainers is that there is no point of impact on the knee joints when using them. Using an elliptical trainer can not only prevent, reduce, and alleviate pain in the neck, shoulder, and upper back, but also avoid the impact of running, better protecting the joints and thus providing a higher safety factor. However, elliptical trainers are purely fitness equipment, relatively expensive, and take up a lot of space, making them difficult for ordinary working-class families to purchase individually.
