How did cycling become popular
In the 1800s, early forms of bicycles existed. Although the invention of the bicycle, to this day, is not entirely clear, cycling, as a sport and hobby, soon did become of great interest to the public. Shortly after the bicycle was invented, cycle races began to spread in many areas.
When was the Bicycle invented?
Bicycles, of some types, appear as early as Leonardo da Vinci’s sketches from 1493. It is not clear if this device was actualized but indicates concepts that became used later on. By the early 1800s, several types of bicycles were made. Initially, different forms existed. However, among the earliest forms of what would become the forerunner to the modern bicycle was the Draisine (Figure 1), a two-wheeled vehicle invented by Karl Drais. This bicycle consisted of front steering and was pushed along by a person's feet, as pedals had not been introduced. The bicycle frame is familiar to us, which made it different from earlier forms and gave it an appearance we would recognize.
After this development, the next big innovation was the use of pedals. This is not clear when this happened, but Kirkpatrick Macmillan could have invented a Scottish blacksmith. The key design modification was when Pierre Michaux and Pierre Lallemen put the pedals at the front wheel and put a seat on the support beam in 1863. This now made the bicycle much easier to control and power, enabling the rider to stay stationary while directing the bike.
With that innovation, cycling soon began to develop as a recreational activity and sport. In particular, cycle races began to develop by the 1860s. The first documented cycle race of a measured distance was in Paris, a 1200 meter event held in Saint-Cloud Park. Bicycles, some similar to our own forms, now began to appear throughout Europe and North America. In the United States, early bicycle manufacturers were also carriage manufacturers.
Riding schools and competitions began to develop by 1869, although in the United States already by then the sport of cycling began to decline because early bicycles were often uncomfortable, particularly the seats.
How did bicycling change at the end of the 19th Century?
In the 1880s, the so-called safety bicycle was developed, emphasizing greater steering control and more even wheel sizes, giving the rider greater control and greater comfort by now giving back wheel chain control. By improving safety and comfort for cycling, these new so-called safety bikes also became the first bikes to be popular among both sexes and for different age groups. At this point, cycling begins to be pervasive among the wider population and at different age groups, including the elderly.
In the late 1880s, improvements with rubber wheels made bicycles also more able to travel rougher surfaces. The oldest cycling club in the US was soon established, in 1887, in St. Louis, called the St. Louis Cycling Club. In the 1890s, the roadster bike became among the most popular designs, which saw now bicycles developed for men and women, where women's bikes accommodated the fact they wore skirts and dresses which could get caught on the back wheels. Thus a design to prevent this was developed.
While bicycle design continued to improve in the early 1900s, Europe and the United States soon diverged in their cycling perceptions. In the United States before 1910, the automobile, such as the Model T, began to gain much greater popularity, which led to a major decline in cycling. In fact, in the United States, cycling soon began to be associated with a children's activity, and adults largely stopped using cycling as a means of transport to work or recreation. In Europe, cycling, even with the introduction of cars, continued to be popular.
Clubs, tours, and racing contests continued in their popularity. The Tour de France is perhaps among the best known European cycling events, where it has been running since 1903. In the 1930s, multiple gears were introduced for racing bikes. This now made cyclists have easier control of their bikes as they changed and focused on different inclines in their rides.
What is the History of the Bicycle Lock?
Not surprisingly, as soon as bicycles became more popular, people began stealing them. In parallel with the development of bikes, people began to develop bike locks to protect their investment. Starting in the early 20th century, companies began creating bicycle locks. The earliest bike locks were either larger steel locks designed to fit between the spokes or bicycle locks attached to chains that connected the wheels to the frame. 
In the 1930s, Optimus, a German company, began manufacturing several different-sized steel locks that could be used on a large range of bicycles. Companies in the United States were also manufacturing bike locks and selling them worldwide. Eventually, Optimus switched to pressed steel to create stronger, more secure locks. Even during World War II, companies continued to sell bike locks to militaries fighting during the war.  Today, bicycle locks are made by hundreds of companies across the world to protect bikes. Bicycle safety is still important, and you can check out some of the best modern bicycle locks made today in this article. Fortunately, modern locks do a better job securing bikes than the ones made back in the 1920s.
Why did bicycling become less popular in Europe after World War II?
In parts of Europe, there were declines in the use of bicycles after World War 2. For the most part, most countries began to focus their transport spending on building roads or rail throughout the second half of the 20th century, and in particular as part of the reconstruction period after the war. In the Netherlands, in the 1960s, it was evident cycling did begin to decline as cars displaced cyclists from roads.
In the early 20th century, the Dutch had among the highest per capita use of bikes globally. By 1970, it was evident that motor deaths became a leading cause of death for young people, which led to a re-emergence of the importance of the bicycle in the Netherlands as a means for transport. Major campaigns began to pressure politicians to develop specific infrastructure that segregated cyclists from motor traffic.
This led to one of the first nationwide master plans for cycling that focused on developing nationwide bike routes and protected areas. The led to also dedicated bicycle garages, changing facilities, and parking areas throughout the country. The transformation and campaigns by Dutch activists to make cycling part of an integrated transport planning became the model where other countries have since tried to replicate, where now cycling is often seen as one of the best transport options or at least part of other options for short distances in urban regions and the countryside.
How did cycling become popular in the United States in the 1980s?
In the 1980s, what began as mainly an upper-class interest in health and fitness in the United States, began to renew interest in cycling. While the overall number of adult cyclists was low in the United States, weekend recreational use began to come back among some adults. By the 1980s, mountain biking was a new sport that helped put interest back in cycling forms. In the 1990s, renewed interests in bicycle racing also helped Americans take more interest in cycling.
Additionally, bicycling played an integral role in the extraordinarily popular movie E.T. directed by Steven Spielberg. After the movie played in theaters, supercharged bike sales for kids and pre-teens. Classic kid bikes were replaced by bicycles that mimicked the Kuwahara Model 3003 ridden by Elliot in the movie.
During the first decade of the 2000s, high oil prices also increased urban cycling popularity in the United States. Dedicated bicycle lanes began to reappear as pressure groups formed in American cities. The rise of oil prices, high traffic, and increased interests in health, with obesity becoming a major problem, has led to cycling being of high interest in many countries in Europe, the United States, and East Asia. Almost every major city now has a master plan for integrating cycling with urban transport. The biggest recent trends have been urban communities introducing docking stations and dock-less bicycles as part of their urban transport plans.
Cycling was developed as a sport and leisure activity in the early 1800s. Early bicycles were uncomfortable and often dangerous, making them less amenable to the wider public until the 1870s when bicycles began to be developed, having safety as a major priority. This led to the increase of cycling among the general population. That changed in the 1900s, as the automobile led to the decline of cycling. More recently, however, cycling has had a new lease, as it is now seen as part of larger urban transport plans and recreation and sport.
