BMX freestyle: official game rules briefly
Freestyle BMX is today considered one of the most developing extreme disciplines in the world. The essence of the competition lies in performing various tricks on special BMX class bikes. Currently, tournaments in this extreme sport are held in 5 categories:
- a park;
Each BMX freestyle variation has its own rules, requirements and features.
The International Cyclists Union (UCI), founded in April 1900 in Switzerland, is responsible for setting the rules and organizing the largest world championships in this sport. It consists of 5 confederations uniting the national federations of their continents:
- UEC (Europe);
- ACC (Asia);
- COPACI (America);
- CAC (Africa);
- OCC (Oceania).
Under the auspices of the International Cycling Union, the BMX Freestyle World Championships are held every fall in every odd year. In addition, the UCI leadership has achieved the inclusion of this type of motorcycling in the program of the 2020 Summer Olympics.
The main variations of the BMX freestyle are the following:
In this type of freestyle motorbike riders (riders) use public and city places to perform their stunts. The most common “figures” for tricks are curbs, ledges, handrails, shores, stairs and other obstacles. The styles of street cyclists can be different, but the complexity of the elements is judged equally by the judges.
Athletes use BMX bikes with shortened wheelbases and steep corners to simplify acrobatic stunts in Street Freestyle competitions. This makes bicycles light and easy to maneuver. Among the minuses, it is worth highlighting the decrease in stability at high speeds, for example, on the ground or ramp.
As part of the street BMX competition, several competitions are traditionally held. Some are corporate, while others are tournament ones. In the first case, we are talking about a performance to attract sponsors, in the second – to advance on the grid of the main competitions.
- Plain (Flatland).
This type of BMX freestyle requires special skills, but is ideal for beginner riders. Cyclists spend several hours a day training tricks on the plain.
Flatland is wrong to call a simple freestyle because it has so many nuances. To perform the tricks, riders use a flat, smooth surface, for example, a basketball court or recently paved parking. All major elements are performed by rotating and balancing the bike and various body positions. Professionals prefer to use knurled aluminum pegs to make cycling more difficult.
The classic plain BMX features a short wheelbase and a reinforced frame. On short wheels it is easier to stand and carry out rotations, and a reinforced frame allows the projectile to withstand a serious vertical load on different parts of the structure. Freestylers often add extra pegs to the bike at the end of each wheel axis. Brakes are allowed of any type.
The most difficult and spectacular BMX freestyle disciplines include:
The essence of the competition in demonstrating tricks in skateparks. This discipline is characterized by ski jumping and frequent transitions in more often. Skateparks can be made of concrete, metal or wood. The main requirement for them is the reliability of the design. The style of riding depends on the style of the park. The wooden structure is suitable for a smooth style, the concrete structure for a rhythmic one.
To date, the organizers of major international competitions prefer to equip concrete skateparks in the open air. They are more expensive, but differ in a large number of monolithic obstacles, in addition, they are always reliable and durable. Wooden structures are used in short-term commercial tournaments.
- Vert (Vert Ramp).
This freestyle discipline involves performing stunts on a special track in the form of 1/2 pipe (like a halfpipe in snowboarding). Two quarters of the work are set opposite each other, acting as a mini-ramp with a height of 2.5 to 3.5 m. At the World Extreme Games, a large air ramp is used at an altitude of 8.2 m. The pipe faces should have extensions for a vertical transition. Also, coping (a special metal tube) is always installed on the edges of the ramp, which helps riders to grind.
All tricks are performed in the air after lifting with each jump. The result of the element should be a 180 degree rotation to go to the next acceleration. Professionals manage to do tricks in the upper part of the ramp before the exit to its center.
- Track (Trail).
Rough trails are used as official race tracks. Frequent jumping riders lead to a strong compaction of dirt. Jumps on one line in Trail-BMX are called “packs”. Experts identify a series of 4, 6 or 8 “packs”. Such tracks are characterized by a high level of sliding and a large number of irregularities associated with mounds and depressions from the wheels.
A “dirty” jump involves a steep take-off and a sharp, difficult landing. These elements are performed on the mounds. There should be enough space between them to land the bike. A moderate gap between obstacles is 0.7 m. To complicate the route, organizers can add low earthen or wooden jumps.
In this type of freestyle, experienced riders use only the rear brake.
Only athletes with BMX bikes are allowed in official competitions. The frame of such bicycles should be durable and light. The reliability of the design is ensured by a double triangle with a common base, as well as special mountings for the sleeve, which have a relatively large thickness and area. To increase the strength, additional kerchiefs are used for the rear feathers of the frame and the main pipes.
Wheels should be between 30.5 and 50.8 cm in diameter (depending on the freestyle discipline). Rims have a wide profile and can be single, double or triple. The standard number of knitting needles is 36 pieces in 3 crosses. Recommended pressure in the chambers is from 3 to 7 atm.
The steering wheel is a two- or four-tube design with a crossbar to increase strength. Grips are traditionally pulled at the ends of the steering wheel (handles for improved grip of hands with tubes). The steering wheel mount with a fork should be made of a single block of aluminum. The fork itself consists of a stem, two legs and support plates.
A plastic, carbon or metal peg is installed on the axis, which is needed to perform tricks on the railing and faces.
Pedals are allowed magnesium, plastic or aluminum.
Brakes can be of different types. Some riders do not “load” the BMX with the braking system at all.
In training and competitions, athletes must wear a protective helmet with a chin. Optional but recommended protective equipment in the BMX freestyle includes knee pads, elbow pieces, gloves, plastic safety glasses, an elastic suit with reinforcements on the shoulders, spine and lower back.
