A start gate can be made from various materials

Main:
The final race of the event in any one given class. Once riders have qualified through their motos and other quarter and semi finals, the main determines the riders final placings for awards and points at any given race event.

Holeshot:
The first person to take the lead in the race at a certain point. Loosely defined in BMX as the first rider to reach turn one during a moto.

Starting gate:
The structure at the beginning of the track that holds up to eight riders. When triggered by an electronic voice box, the front portion of the gate falls forward allowing the riders an equal chance to start racing on the track.

Berm:
The raised portion of dirt in any one of the corners (turns) on the track that allows riders to ride through corners and maintain speed and momentum. Most modern day turns on BMX courses are bermed corners although some may be flat or level.

Lip:
The top part of the front of a jump, which can send a rider into the air over the obstacle. The “lip” is also known as the “takeoff”.

Getting ‘Air’/Jumping:
When a riders wheels leave the ground over any given jump or obstacle.

Manualing a jump keeps a riders wheel on the track

Manual:
When a rider keeps their back wheel on the surface of the track over any given jump to keep traction and/or improve momentum.

Roller:
A small, usually no larger than three foot tall, obstacle (jump) on a BMX course with a smooth, rounded, front and top with a long backside.

Tabletop:
An flat-top obstacle on a BMX track, varying in size, with a “lip” on the front side, a flattened top and smooth, rolling backside.

Double:
A variably sized jump consisting of two “rollers”, the first roller is the “takeoff”, with the back part of the second being the landing (or backside).

Step-up:
Similar to a Double, but with two different sized rollers. Typically the first roller is smaller and the second roller is taller, forcing a rider to jump higher (Step-up) to clear the obstacle.
