BMX Racing

What is BMX Racing?

BMX Racing (Bicycle Motocross Racing) is a spectacular cycling discipline in which up to eight riders compete simultaneously on a specially designed off-road track with jumps, banked turns and obstacles. Races last only 30-40 seconds and are characterized by explosive speed, technical skill and tactical ability.

The discipline was developed in California in the 1970s and has evolved into a globally recognized Olympic sport. BMX Racing combines elements from motocross, track cycling and sprint disciplines into a unique competition format.

History and Development

Origins in the 1970s

BMX Racing originated in Southern California, where children and teenagers rode their bicycles on self-built off-road tracks and imitated their motocross idols. The first official BMX track opened in 1970 in Long Beach, California.

Internationalization and UCI Recognition

In the 1980s, the sport spread worldwide. The Union Cycliste Internationale (UCI) took responsibility for BMX Racing in 1993 and has organized world championships annually since then.

Olympic Recognition

BMX Racing debuted at the 2008 Olympic Games in Beijing and has since established itself as a permanent Olympic discipline. More details on Olympic history can be found under BMX at the Olympics.

Track Layout and Characteristics

Start Ramp (Start Hill)

The start ramp is an 8-meter high platform from which all riders start simultaneously. An electronic gate releases the start and ensures fair conditions. The first meters after the start are crucial for positioning in the race.

Track Length and Layout

A standard BMX Racing track is 350-400 meters long and contains various elements:

Track Surface

Professional BMX Racing tracks are built from compacted clay or asphalt. The surface must be grippy while enabling fast riding.

Competition Format and Rules

Qualification Rounds

Each rider first completes several time trials to determine their starting position for the knockout rounds. The best times qualify directly for later rounds.

Knockout System (Motos)

After qualification, eight riders each compete in so-called "motos". The first four riders of each heat advance to the next round:

1. 1/16 Final - Riders are divided according to qualification times
2. 1/8 Final - Top 4 of each heat advance
3. Quarterfinals - Further reduction to 32 riders
4. Semifinals - The best 24 riders
5. Final - The top 8 compete for victory

Race Rules

Allowed:

• Body contact within reasonable limits
• Overtaking in turns and on straights
• Pumping and manualing over obstacles

Prohibited:

• Intentional pushing or blocking
• Cutting corners outside the track
• Holding onto other riders
• False start before gate opening

Riding Technique and Tactics

Start Phase - The First 3 Seconds

The start is crucial in BMX Racing. A poor starting position is difficult to recover from on the short track.

Optimal Start Technique:

1. Shift body weight forward, just before gate opening
2. Explosive acceleration with maximum leg power
3. Rapid cadence in the first 3-4 pedal strokes
4. Transition to high gear for speed building

Jumping Techniques

Manual (Rolling over Jumps):

On smaller jumps, it is often faster to lift the front wheel and "roll" over the jump instead of jumping. This saves time and maintains speed.

Jumping (Active Jumping):

On larger jumps, active jumping is necessary. The technique requires:

• Compression before takeoff
• Explosive extension at takeoff
• Body tension in the air
• Soft landing with bent knees

Pumping:

By moving the body up and down, energy is converted into speed without pedaling. This technique is essential in rhythm sections.

Cornering Strategy

Banked Turns (Berms):

• Maintain high speed
• Ideal line at the top edge of the turn
• Lean body inward
• Don't brake, but pump

Flat Corners:

• Controlled drifting
• Brief braking before the corner
• Low position, elbows out
• Fast acceleration exit

Overtaking Maneuvers

Overtaking in BMX Racing is risky but sometimes necessary:

• Outside overtaking: Safer, but longer path
• Inside overtaking: Riskier, requires perfect timing
• Overtaking in the air: For professionals on large jumps

BMX Racing Bike Specifications

Frame and Geometry

BMX Racing bikes are specifically designed for speed and agility:

Gear Ratio

The gear ratio is individually adjusted to rider and track. Typical values range between 41:16 and 43:16.

Tires and Air Pressure

BMX Racing tires are narrow (1.75 - 1.95 inches) with low profile. Air pressure ranges between 5.5 and 7.5 bar, depending on track surface and rider weight.

Equipment and Safety

Mandatory Equipment

Helmet:

A full-face integral helmet is mandatory. Modern BMX helmets meet the ASTM F1952 standard. More information on helmets in cycling.

Additional Protective Equipment:

• Long-sleeved jersey and long pants
• Gloves
• Shin guards
• Elbow protectors
• Neck brace (optional, but recommended)

Number Plate

Each rider wears a number plate on the handlebar with start number and national flag.

Training and Preparation

Physical Requirements

BMX Racing requires explosive power, speed strength and excellent coordination:

Training Components:

1. Strength Training - Leg press, squats, plyometric exercises
2. Sprint Training - 30-50m sprints for start phase
3. Technique Training - Track-specific riding
4. Endurance Training - Aerobic base for competition day with many heats
5. Coordination Training - Balance, timing, reaction speed

Mental Preparation

The short race duration and knockout format require extreme mental strength:

• Focus on the moment
• Dealing with pressure in final heats
• Quick recovery after mistakes
• Risk willingness vs. control

Important Competitions

UCI BMX World Championships

The annual world championship is the most prestigious event outside the Olympic Games. Categories include Elite, U23, Juniors and various age groups.

UCI BMX World Cup

The World Cup series consists of several races worldwide, bringing world-class riders into competition over an entire season.

Olympic Games

Since 2008, BMX Racing has been part of the Olympic program. Qualification is through UCI ranking and continental quota places. Details can be found under BMX at the Olympics.

National Championships

Every nation with organized BMX sport hosts annual championships that serve as qualification for international competitions.

BMX Racing vs. BMX Freestyle

Although both disciplines use BMX bikes, they differ fundamentally:

Professional BMX Racing Scene

Leading Nations

Traditionally, the following countries dominate BMX Racing:

• Netherlands - Strongest nation with many world champions
• USA - Country of origin with large infrastructure
• Colombia - Emerging nation with strong youth development
• France - Top European nation
• Australia - Strong presence at World Cups
