BMX
Officially BMX (Bicycle Motocross)
Bicycle motocross — high-intensity 20-inch-wheel bike sport spanning motocross-style racing on 8-rider tracks with jumps, and freestyle disciplines (park, dirt jump, street, flatland, vert).
What is BMX?
BMX (Bicycle Motocross) is a family of cycling sports using 20-inch-wheel bicycles, originating in Southern California in the late 1960s when children mimicked motocross riders on their bikes. Two main disciplines exist today: BMX Racing (8-rider gate-start heats on 300-400 m dirt tracks with jumps and berms; race lasts 30-45 sec) and BMX Freestyle (spanning Park, Street, Dirt Jump, Flatland, and Vert sub-disciplines). Both are Olympic sports — Racing since Beijing 2008, Freestyle Park since Tokyo 2020. Freestyle Park was won by Charlotte Worthington (GB) in women's and Logan Martin (Australia) in men's at Tokyo 2020. BMX bikes have very short frames, a single gear, no suspension, and pegs (for freestyle) enabling grinds and tricks. Cultural pioneers include Bob Haro (freestyle founder), Mat Hoffman (vert legend), and Ricardo Peixoto (Brazilian street style).

How it works
Objective
Racing: cross finish line first over 3 heats (moto, semifinal, final). Freestyle: highest judge score on trick difficulty, style, and execution.
Match structure
Racing: 8 riders line up on hillside gate, drop = go, sprint down hill, navigate jumps and berms. Top 4 advance per round. Freestyle: 60-sec runs judged 0-100 on tricks, variety, execution, style, and use of course.
Rules
Basic rules
Racing gate start
Mechanical gate drops; 8 riders sprint down the starting hill.
Passing rules
Contact allowed but reckless riding penalised.
Racing distance
300-400 m; 3-4 straights with jumps + 3-4 banked corners.
Freestyle judging
Judges score 0-100 based on trick difficulty, execution, style, variety.
Freestyle bailout
Runners can bail without penalty; only landed tricks score.
Amateur/pro classes
Racing has age-based classes (Boys/Girls, Junior, Elite); freestyle has amateur and pro divisions.
Advanced rules
Racing 'strider' course
Elite BMX Racing tracks feature 8-m start hill and demanding pump-track sections.
Freestyle park elements
Runs typically feature 4-6 major tricks + spins/flips (bar spins, tail whips, 360s, 720s, flairs, front flips).
Vert BMX
Ramp discipline like skateboarding vert; 720 backflip and 1080 tail whips are contest-winning tricks.
Flatland
Balance and manoeuvring tricks on flat pavement — no ramps, no obstacles. Rare Olympic-recognised discipline.
Best Trick contests
Format at X Games — one big-trick attempt for top prize.
Scoring
Racing: finish position determines advancement. Freestyle: 0-100 judge score for runs and tricks.
| Action | Points |
|---|---|
| Racing 1st in heat | Advance to next round |
| Racing final 1st | Event win + UCI points |
| Freestyle Park run | 0-100 (judge panel average) |
| Freestyle best trick | 0-100 for single trick attempt |
Win condition · Racing: win final heat. Freestyle: highest cumulative score.
Playing area
Called
BMX track / freestyle park
Dimensions
Racing: 300-400 m dirt track with 5-8 m starting hill. Freestyle: skate/BMX park with quarterpipes, spines, boxes, rails.
Racing tracks feature 8-lane starting gate, high dropped starting hill, sequential jumps (rollers, tabletops, doubles), and 3-4 banked corners. Freestyle parks use concrete or plywood transitions.
Equipment
BMX bike
20-inch wheels, short chromoly steel frame, single gear (racing 45/16; freestyle typically 25/9 or similar micro gear), no suspension.
Racing helmet (full-face)
Mandatory in racing; DOT-rated.
Freestyle helmet
Skate-style helmet common in park/street.
Elbow, knee, gloves
Required in racing; optional freestyle (except contests).
Racing jersey and pants
Motocross-style protection.
Pegs (freestyle only)
4-6 inch metal tubes on axles for grinds and stalls.
Officiating
Racing: marshals enforce contact rules and DQ recklessness. Freestyle: 5 judges score runs.

- Track Marshals
- Freestyle Head Judge
- 5 Judges (freestyle)
Strategies
Racing gate start
Perfect the gate reaction and 8-pedal sprint — often decides the race.
Pumping over jumping
Elite racers pump the track (using body compression) rather than jumping — faster.
Line choice
Inside vs outside line through berms; choose based on start position.
Freestyle originality
Judges reward original combos and use of the entire park — same tricks in different sequences don't score as well.
