These are things you might hear at BMX tracks, pump tracks, or MTB bike parks. Some BMX'ers ride MTB too, and everyone rides pump tracks

· Backside: The downward side of an obstacle. Sometimes called downside.

· Bail: Leaping off the bike to avoid a more serious crash.

· Booter: A large jump that you have no choice but to send.

· Case: Coming up short on a jump. Most of the time casing ends in crashing.

· Class: 20-inch wheel bikes (the rim is actually 16" but with tire it is 20")

· Clips: A pedal with a mechanical piece to lock a special shoe into it for max power. Clips refer to clipless pedals. They don't use a toe clip, thus they are clipless.

· Cruiser: Cruising on 24-inch wheel bikes (the rim is actually 20" but with tire it is 24")

· Dialed: When your set up is perfect allowing you to ride to the top of your ability.

· Double: Two bumps on one obstacle.

· Face: The upward side of an obstacle.

· Flats: A pedal with a flat surface and no mechanical attachment to your shoe.

· Flow: When the track obstacles meld into another perfectly and everything just goes smoothly

· Gap: A jump with a space between the take-off and landing point, like a double

· Gate: It’s at the starting hill. The gate is where the race starts. There are a few styles of gates, but they all fall forward.

· Gear inches, rollout: How far your bike goes in one crank rotation based on gearing and tire diameter. There are online calculators for this like BMX Ultra.

· Gear Ratio: Divide the front teeth by the rear teeth and get a ratio. This ratio is a quick starting point for tuning. For ISO 406 starting point is 2.75 and ISO 451 about 2.6.

· Gearing: This means to the front and rear gears. If the front is 44 teeth and the rear is 16 it is 44/16.

· Holeshot: From the gate to the first turn, the first straight. The rider that leads the others down the first straight "took the holeshot."

· Loose: On the edge of control and losing control.

· Manual: Everyone has definitions for what is and isn't a manual. Basically, it's like pumping on one wheel. You lift the front up over the obstacle and push the rear down.

· Mash: Slow crank cadence.

· Moist: Getting’ moist, that’s moist boy, it means you did something sorta stupid and you crashed and you’re hurt.

· Moto: The race part. In most races there are three motos per rider group. In UCI races motos are also called ‘heats.’

· Obstacle: Anything not flat on the track.

· Pits: The area around the track where you can find food vendors and have your non-race space. Also, it is where hordes of semi-feral kids rove.

· Pro-section: A big jump. Pro-sections are basically two ramps; jump off one, land on the other. In between the jumps there is a wild jungle filled with saltwater crocs.

· Pumping: Pumping is used to maintain or gain speed over obstacles. It's the up-down rhythm you use to get your bike across rollers.

· Rad: Awesome, cool

· Rail: To ride a corner fast and high in one line like you are on rails.

· Rhythm Section: A rhythm section is several rolling bumps (rollers) placed together in a grouping. Kinda like 'whoops' at a motocross track.

· Roller: A single low rounded bump.

· Send: Full send, send it! Going all out, max performance

· Spin: Fast crank cadence. Spin to win in BMX.

· Staging: The area on or near the hill where riders are organized into their motos before loading in the gate.

· Starting Hill, The Hill: The place where you start races. Can’t miss it.

· Step-down: A step down is like going down the stairs.

· Step-up: A step up is like going up the stairs.

· Tabletop: A tabletop is like a butte in geography. They are great to learn jumping skills on. Everyone likes tables.

· Taco: When a wheel has been bent and folds over like a taco shell

· Triple: Three bumps on one obstacle.

· Turn: A turn is a banked corner, sometimes called a berm. They are made of dirt or asphalt. Most BMX tracks have 3 turns. Some have 4.

· Whip: When the rear of bike is thrown sideways in the air for a little style
