One big group leads all bike races. 
They give licenses to the riders. This helps people race fairly. They also run the World Championships. Winners of these races get a special shirt. It is white with five bright colors. It is called a rainbow jersey.
This group helps keep the sport safe. They made rules for wearing helmets. Now, riders must wear them all the time. It is a very big job to lead the world of cycling.
The Union Cycliste Internationale, or UCI, leads the world of cycling. 
The UCI manages many ways to ride bikes. This includes road racing and track cycling. It also covers mountain biking, BMX, and gravel riding. They run the World Championships for men and women. Winners of these races earn a rainbow jersey. This is a white shirt with five colored bands.
The group also makes sure races are fair. They give licenses to riders. They also make rules about doping, which is using drugs to win. They even made rules for wearing helmets to keep riders safe.
In 2004, the UCI built a large track in Switzerland. This is called a velodrome. It is 200 meters long. The UCI also helps organize races all over the world. In 2007, they gave special status to a race in Australia. This showed that cycling is a global sport.
The Union Cycliste Internationale, or UCI, is the main group that runs cycling sports around the world. 
Running a global sport involves many important steps. The UCI issues racing licenses to riders so they can compete. They also make sure everyone follows the rules. This includes making rules about doping, which is using drugs to win unfairly. They even worked on rules for safety, like wearing helmets. For a long time, many professional road riders refused to wear them. After a rider named Andrei Kivilev died during a race in 2003, new rules were made. At first, riders could take them off during long climbs. Later, the rules changed so that helmets must be worn at all times.
History shows how the UCI grew from a small group into a large one. It was founded on April 14, 1900, in Paris. Five countries helped start it: Belgium, the United States, France, Italy, and Switzerland. In the beginning, not every country had an equal vote. Votes were handed out based on how many tracks, or velodromes, a country had. France had the most with 18 votes, while Germany and Italy had 14 each. Later, the group split into two parts to manage amateur and professional riders. They stayed split for many years until they merged back into one UCI in 1992.
There are many interesting facts about how the UCI works today. In 2004, they built a 200-meter velodrome at their World Cycling Centre. In 2007, they gave special status to the Tour Down Under in Adelaide, Australia. This was the first time a major event outside of Europe received this honor. The UCI has also had to make very tough decisions about international politics. After the Russian invasion of Ukraine in 2022, the UCI stopped Russian and Belarusian teams from competing in international events. In 2023, they started a process to let those riders compete as neutral individuals instead.
Cycling is a sport filled with skill and many different types of machines. In the past, people raced on many kinds of bikes. Some were called tandems, which are bikes for two people. Others were called recumbents, where the rider lies down flat. The UCI banned recumbent bikes from official competitions in 1934. They also made rules about how bike frames should look. In 2000, they banned any frames that did not have a seat tube. These rules help make sure that racing stays fair for everyone. Whether on a mountain or a paved road, the UCI keeps the sport moving forward.
The Union Cycliste Internationale, commonly known as the UCI, is the global governing body for the sport of cycling. 
To manage the sport effectively, the UCI uses several administrative mechanisms. It manages the classification of races and maintains a complex points ranking system for men and women. The organization also oversees the World Championships, which are major global competitions. To fund these activities, the UCI uses a specific system for championship events. When a member nation hosts a championship, they must pay the UCI 30 percent of ticket receipts for track events and 10 percent for road events. From that collected amount, the UCI keeps 30 percent and distributes the remainder to the competing nations based on how many events they entered. In the early 1900s, the highest gate money recorded was 600,000 francs during a 1903 event in Paris.
Cycling is divided into several distinct disciplines and categories. The UCI oversees road racing, which can take different forms. Some races use a massed start, where many riders begin together. Other formats, like those historically organized in Britain, use a time trial, where riders race against the clock. There are also track disciplines, such as the keirin, which was added to the Olympic program. The UCI also regulates the equipment used in these categories. For example, they banned recumbent bicycles—machines where the rider lies in a horizontal position—from official competitions in 1934. In 2000, they also banned all bicycle frames that did not include a seat tube.
The history of the UCI is rooted in the early days of organized cycling. It was founded on April 14, 1900, in Paris by the national cycling organizations of Belgium, the United States, France, Italy, and Switzerland. The UCI was created to replace the International Cycling Association (ICA) following a dispute over how Great Britain should be represented at championships. Initially, voting power within the union was not equal among all members. Instead, votes were distributed based on the number of velodromes, or cycling tracks, a nation possessed. France held the highest number with 18 votes, followed by Germany and Italy with 14 each. Britain held eight votes, a number attributed to the inclusion of many doubtful grass tracks.
As the sport grew, the UCI underwent significant structural changes. In 1965, under pressure from the International Olympic Committee (IOC), the UCI created two separate bodies to manage different types of athletes. The International Amateur Cycling Federation (FIAC) was based in Rome, while the International Professional Cycling Federation (FICP) was based in Luxembourg. The FIAC was a larger organization with 127 member federations and was largely dominated by amateur cyclists from the Eastern Bloc. These two groups operated mostly separately until 1992, when the UCI reunified them into a single organization. Following this merger, the UCI relocated its headquarters to Aigle, placing it near the IOC in Lausanne.
The UCI has also navigated complex political and safety challenges. For many years, professional road cyclists resisted wearing helmets. Following the death of Andrei Kivilev during the 2003 Paris–Nice race, the UCI introduced new safety rules. Initially, riders could remove helmets during climbs longer than five kilometers, but rules were later revised to make helmet use mandatory at all times. The organization also deals with international geopolitics. After the 2022 Russian invasion of Ukraine, the UCI prohibited Russian and Belarusian teams from international events and stripped them of scheduled events. By May 2023, the UCI approved a process to allow these riders to compete as individual neutral athletes.
Beyond rules and politics, the UCI manages the prestige of the sport through symbols and major events. The winner of a UCI World Championship is awarded a highly recognizable rainbow jersey. This white jersey features five colored bands across the chest and can only be worn in the specific discipline and category for which it was won. In 2007, the UCI expanded its influence by awarding ProTour status to the Tour Down Under in Adelaide, Australia. This marked the first time an event outside of Europe received such status. Through these rules, rankings, and traditions, the UCI continues to shape the global landscape of cycling.
