Each poster is packaged with a gray cardboard sheet in a transparent plastic sleeve. The bicycle is a means of transport that was invented in the 19th century. The first models resembled balance bikes much more than modern bicycles and did not have pedals. Bicycle pioneers began adding pedals to existing models in the 1860s, which gave birth to the modern bicycle. Over the years, the bicycle has undergone many innovations and improvements, particularly in terms of design, performance, and safety. Bicycles began to be mass-produced at the end of the 19th century, making them more affordable for the general public. By the early 20th century, bicycles had become a popular means of transport and were used for many activities, including tourism and sports competitions. Since then, the bicycle has continued to evolve and adapt to the needs of society. Today, there are many different types of bicycles, suited to activities such as performance cycling, mountain biking, road cycling, folding bikes, etc. The bicycle is also considered a sustainable and eco-friendly means of transport, and more and more people are choosing to use it for daily commuting.
