What is Bike Trials?
International competition: the world stageThe classes above describe grassroots and national events — but bike trials is also a world sport with a full international calendar. Two federations govern it globally: the Union Cycliste Internationale (UCI), which has run the UCI Trials World Championships since 1986 and a World Cup series since 2000, and the Biketrial International Union (BIU), a trials-only body founded in 1992. Both crown world champions in the 20-inch and 26-inch classes, supported by continental titles such as the UEC European Championships and a deep network of national series.

Bike trials is a sport in which one's bike skills are tested. They are tested through a series of sections, or trials. I assume that this is how the name bike trials came about. Observed bicycle trials is another name for bike trials. "Observed" refers to the checker watching the rider and counting penalty points. Frequently asked questionsWhat is bike trials?Bike trials is an individual sport in which a rider maneuvers and balances a special bicycle through marked "sections" — artificial or natural obstacle courses — trying to get through with as little physical contact with the ground as possible. Each touch, called a "dab", adds penalty points. How is bike trials scored?A rider loses 1 penalty point each time a part of the body touches the course, and 5 points for touching with more than one part at once. Reaching 5 points ends that section for the rider until the next loop. The lowest total score wins. What are the competition classes?In the United States there are four classes — Beginner, Sport, Expert and Pro. Depending on class, riders get 2 or 3 minutes per section, usually across about five sections ridden two or three times. What is the difference between 20-inch and 26-inch trials bikes?20-inch "mod" bikes are purpose-built, single-gear machines favoured by beginners and younger riders for their simplicity and crash clearance. 26-inch "stock" bikes run larger wheels and multiple gears. Competition is held in separate categories for each. Where does the name "trials" come from?A "trial" is the act of testing.
