Do you think bicycles are the most ergonomic products at present?

Bicycle was originally designed as a simple short-distance means of transportation, but the development of bicycle can be divided into two purposes, one is environmental protection means of transportation, and the other is the most popular means of sports and entertainment at present. Apart from some medical health certificates, the main reason for the change from transportation to entertainment should be the founder of Li Lai brand in England, who is an Englishman. I came to Hong Kong to do business and went to the hospital one day after my business was successful. As a result, I was diagnosed with pneumonia Because pneumonia was still terminally ill that year, the doctor told him that the days were running out and he decided to go back to England to die. After returning to England, he saw a bicycle that was very popular at that time. Because he had nothing to do, he bought a bicycle to ride every day. Anyway, he just waited for death and rode around, but strangely, the doctor told him that he had been alive for a long time, so he went to the hospital for an examination and found no symptoms of pneumonia. Therefore, the founder of Li Lai brand thinks that bicycles should not only be used as a means of transportation, but also be a good exercise tool beneficial to health, so he decided to engage in the manufacture of bicycles for the benefit of mankind.
