What is BMX?

BMX bikes are a type of off-road bicycle that are designed for riding on dirt tracks, BMX parks, and concrete streets. BMX stands for “Bicycle Motorcross”. BMX bikes are typically single-speed with 20-inch wheels. The first BMX bikes were made in the 1970s and were inspired by motocross motorcycles. BMX bikes have since evolved into different types of bikes designed for different riding styles

What is a BMX Bike?

A BMX bike is a small, lightweight bicycle designed for off-road riding on dirt tracks, BMX parks, and concrete streets. BMX bikes typically have 20-inch wheels, one gear, and no brakes. The first BMX bikes were made in the 1970s and were inspired by motocross motorcycles. BMX bikes have since evolved into different types of bikes designed for different riding styles.

History of BMX Bikes

BMX bikes were first created in the 1970s as off-road bicycles for riding on dirt tracks. The first BMX bikes were inspired by motocross motorcycles and were designed to be lightweight and durable. BMX bikes quickly gained popularity among young riders who enjoyed riding on dirt tracks and doing tricks. In the 1980s, BMX bikes evolved into different types of bikes designed for different riding styles, such as freestyle and racing. Today, BMX bikes are ridden by people of all ages all over the world.

Types of BMX Bikes

There are two main types of BMX bikes: freestyle and racing. Freestyle BMX bikes are designed for riding on ramps and doing tricks, while racing BMX bikes are designed for racing on dirt tracks. There are also two sub-types of freestyle BMX bikes: vert and street. Vert BMX bikes are designed for riding on vert ramps, while street BMX bikes are designed for riding on concrete streets.

Freestyle

Freestyle BMX bikes are designed for riding on ramps and doing tricks. Freestyle BMX bikes have a shorter wheelbase than racing BMX bikes, which makes them more maneuverable. Freestyle BMX bikes also have thicker tires than racing BMX bikes, which makes them better suited for riding on ramps and concrete streets.

Vert

Vert BMX bikes are designed for riding on vert ramps. Vert BMX bikes have a shorter wheelbase than street BMX bikes, which makes them more maneuverable. Vert BMX bikes also have thicker tires than street BMX bikes, which makes them better suited for riding on vert ramps.

Street

Street BMX bikes are designed for riding on concrete streets. Street BMX bikes have a longer wheelbase than vert BMX bikes, which makes them more stable at higher speeds. Street BMX bikes also have thinner tires than vert BMX bikes, which makes them better suited for riding on concrete streets.

Jumping/Dirt

Jumping/dirt BMX bikes are a hybrid of street and vert BMX bikes. Jumping/dirt BMX bikes have a shorter wheelbase than street BMX bikes, which makes them more maneuverable, but they also have thicker tires than street BMX bikes, which makes them better suited for riding on dirt tracks and concrete streets.

Racing

Racing BMX bikes are designed for racing on dirt tracks. Racing BMX bikes have a longer wheelbase than freestyle BMX bikes, which makes them more stable at higher speeds. Racing BMX bikes also have thinner tires than freestyle BMX bikes, which makes them better suited for racing on dirt tracks.

BMX Bike Sizes

BMX bikes come in two main sizes: 20-inch and 24-inch. The size of the bike is determined by the size of the wheels. The 20-inch BMX bike is the most popular size and is suited for riders of all ages and sizes. The 24-inch BMX bike is typically ridden by taller or older riders.

Anatomy of a Modern BMX Bike

A BMX bike typically has the following parts:

  • Frame: The frame is the main structure of the bike and is made out of metal (usually steel or aluminum). The frame includes the following parts:
  • Top tube: The top tube is the horizontal tube that runs from the front of the bike to the back.
  • Down tube: The down tube is the vertical tube that runs from the head tube to the bottom bracket.
  • Head tube: The head tube is the part of the frame that the fork and handlebars attach to.
  • Bottom bracket: The bottom bracket is where the pedals attach to the frame.
  • Seat tube: The seat tube is the part of the frame that the seat post and saddle attach to.
  • Chain stays: The chain stays are the tubes that run from the bottom bracket to the rear dropouts.
  • Seat stays: The seat stays are the tubes that run from the seat tube to the rear dropouts.
  • Rear dropouts: The rear dropouts are the parts of the frame where the rear wheel attaches.
  • Fork: The fork is the part of the bike that the front wheel attaches to. The fork is attached to the frame at the head tube.
  • Handlebars: The handlebars are the part of the bike that the rider holds on to. BMX bikes typically have handlebars that are higher than the seat.
  • Wheels: BMX bikes have two wheels, a front wheel and a rear wheel. The front wheel is typically smaller than the rear wheel.
  • Tires: BMX bikes have tires that are designed for riding on dirt and concrete. The tires are typically wider than the tires on a road bike.
  • Brakes: BMX bikes typically have either coaster brakes or hand brakes. Coaster brakes are brakes that are activated by pedaling backwards. Hand brakes are brakes that are activated by pulling on a lever.
  • Seat: The seat is the part of the bike that the rider sits on. BMX seats are typically smaller than the seats on other types of bikes.

BMX Frame Categories

BMX frames are typically categorized by the following:

  • Size: BMX frames come in two main sizes: 20-inch and 24-inch.
  • Material: BMX frames are typically made out of steel or aluminum.
  • Style: BMX frames come in three main styles: freestyle, race, and jump.

BMX Frame Dimensions and Abbreviations

BMX frames are typically measured by the following dimensions:

  • Top tube length (TT): The TT is the horizontal distance between the head tube and the seat tube.
  • Chainstay length (CS): The CS is the horizontal distance between the bottom bracket and the rear dropouts.
  • Wheelbase (WB): The WB is the distance between the front and rear wheels.

BMX Frame Materials

BMX frames are typically made out of steel or aluminum. Steel frames are typically heavier than aluminum frames. Aluminum frames are typically more expensive than steel frames.

BMX Forks

BMX forks are the part of the bike that the front wheel attaches to. BMX forks are typically made out of steel or aluminum.

Drivetrain

The drivetrain is the part of the bike that transfers power from the pedals to the wheels. BMX bikes typically have a single-speed drivetrain.

Handlebars

BMX handlebars are the part of the bike that the rider holds on to. BMX handlebars are typically made out of steel or aluminum.

Brakes

BMX brakes are the part of the bike that stops the wheels from turning. BMX brakes are typically coaster brakes or hand brakes.

Seat

The seat is the part of the bike that the rider sits on. BMX seats are typically smaller than the seats on other types of bikes.

BMX Bike Gearing Explained

BMX bikes typically have a single-speed drivetrain. This means that the bike has one gear and does not have a derailleur. The gear ratio on a BMX bike is the ratio of the front sprocket to the rear sprocket. The gear ratio determines how easy it is to pedal the bike. A higher gear ratio makes it easier to pedal the bike. A lower gear ratio makes it harder to pedal the bike.

Popular BMX Bike Brands

Some popular BMX bike brands include:

  • Haro Bikes.
  • Mongoose.
  • Kink BMX.
  • Elite BMX.
  • Eastern Bikes.
  • Sunday Bikes.
