A skateboard is a type of sports equipment used primarily for skateboarding. It usually consists of a specially designed maplewood board combined with a polyurethane coating used to create smoother slides and stronger durability. Most skateboards are made with 7 layers of this wood.
The skateboard is moved by pushing with one leg while the other remains on the board, or by pumping one's feet in a structure like a bowl or half pipe. Skateboards can also be used only by standing on the deck while on a downward slope and allowing gravity to push boards and riders. If the riders' main legs are their right legs, they are said to go up "silly;" if the riders' main legs are their left legs, they are said to rise "regular." If the riders are usually ordinary but choose to ride silly, they are said to ride "switches," and vice versa. A skater is usually more comfortable pushing with their hind legs; choosing to push with the front foot is often referred to as riding "mongo", and has a negative connotation of style and effectiveness in the skateboard community.
Recently, electric skateboards have also emerged. It no longer requires a boost from a skateboard by using a foot; not an electric motor pushing board, fed by an electric battery.
There is no regulatory body that declares any rules about what is a skateboard or part of which it is assembled. Historically, skateboarding has been well suited to contemporary trends and to the ever evolving sequence of action performed by riders/users, who require certain functions of the board. The shape of the board depends on the desired function. Longboards are a type of skateboard with a longer wheelbase and larger and softer wheels.
The two main types of skateboards are long boards and short boards. The shape of the board is also important: the skateboard should be rolled up to do the trick. Longboards are usually faster and mostly used for cruising and racing, while short boards are mostly used for performing tricks.

History
- View: Skateboard
- Skateboarding started in California in the 1950s.
The first skateboard is made of roller skates (attached to the board). Skateboarding gained popularity due to surf; in fact, the skateboard was originally referred to as a "curb in the curb". Initially, skateboards are made by hand from wooden boxes and boards by individuals. As the sport becomes more popular, companies start producing skateboards.
Skateboards have gone through the ebb and flow for years. However, since 2000, due to the attention in media and products such as skateboard video games, kids skateboards and commercialization, skateboards have been drawn to the mainstream. As more interest and money are invested in skateboarding, the more skate parks, the better skateboards are available. In addition, sustained interest has motivated skateboarding companies to keep innovating and creating new things.
Skateboarding is a very individual activity. There is no right or wrong way to glide. Skateboarding still has not stopped growing, and skaters will come up with new tricks every time.
The board also continues to evolve as companies try to make them lighter and stronger or improve their performance.
By 2020, Skateboarding will appear for the first time at the Olympics in Tokyo, Japan.

Section
The following description includes the most common skateboards in popular and modern skateboards. Many parts exist with exotic or alternative construction. A complete traditional skateboard consists of a deck (often with griptape applied on top to increase traction), truck (with urethane bus), wheels (with sealed pads), rings, nuts and bolts to accelerate the truck and wheel assembly to the bottom of the deck. The older deck also includes plastic parts such as sides, tails, and guard noses.
Dek
Modern decks vary in size, but most are 7 to 10.5 inches (18 to 27 cm) wide. Wider decks can be used for better stability when skateboarding. Standard skateboard decks are usually measuring between 28 and 33 inches (71 and 84 cm). The bottom of the deck can be printed by design by the manufacturer, blank, or decorated in other ways.
The "Long" board is usually 36 inches (91 cm) long. Plastic board "penny" usually has a length of about 22 inches (56 cm). Some of the larger 27-inch (69 cm) long penny boards are called "nickel" boards.
Longboards, a common variant of skateboards, are used for high speed and rough surfaces, and they are much more expensive. The "old school" boards (made in the 1970s-80s or modern boards that mimic their shape) are generally wider and often have only one pigtail. Variants of the 1970s often have little or no esophagus, while the 1980s model has deeper wrinkles and steeper pigtails.
Grip record
Grip tape is a piece of paper or cloth with adhesive on one side and a surface similar to fine sandpaper on the other side. Grip tape is applied to the top surface of the board to allow the rider's feet to hold the surface and help the skater stay on board while performing the trick. Grip tape is usually black, but also available in various colors such as pink, red, yellow, plaid, camouflage, and even clear. Often, they have a die-cut design to show board colors, or to display the company logo board. Grip tape accumulates dirt and other substances that will inhibit grip, so use a rubber eraser or eraser is required after riding mud or with dirty shoes.
Truck
Attached on the deck are two metal trucks (usually made of aluminum alloy), which connect the wheel and pads to the deck. The trucks consist of two parts.
The top of the truck is screwed onto the deck and is called baseplate , and below it is hangers . The shaft runs through a hanger. Between the baseplate and the hangers are bushing , also rubber or grommet , which provides a bearing mechanism to rotate the skateboard. Busing protects the truck when it spins. The more rigid the busing, the more the skateboard holds to spin. The slower the bushing, the easier it is to turn. Bushing comes in various forms and formulas of urethane as well as durometer, which can affect turning, rebound and endurance. A bolt called kingpin holds these parts together and fits inside the bushings. So by tightening or loosening the kingpin nut, the truck can be adjusted loosely for better and tighter rotation for better stability (useful when landing tricks). The standard kingpin nut size is 3/8 "- 24tpi.The position of the hanger in accordance with the baseplate is also determined by pivot , the rod that enters the appropriate seat in the baseplate.Pivot stops the hanger from rotating around the kingpin. allows some movement around the bushing and therefore is not perfect. The space between the pivot and its seat in the baseplate is filled by pivot cup , the plastic part that will take most of the pivot wear and helps in centering the hanger.
In general the axle width should be chosen close to the width of the deck to be used. For example, the 7.75 "wide deck will usually be fitted with a truck that has axle between a width of 7.5" and a width of 8.0 inches. (The axle size of a standard axle truck is 5/16 "-24tpi UNF, and a thinner" jam "style with an optional nylon key.) A truck that is too wide can make tricks do difficult and can cause the wheels to block when a skateboard is being driven. too small can be difficult to maintain stability and can cause wheel bites to occur while turning.
Longboard special trucks are a newer development. A longboard truck has a king pin placed in a more blunt corner (usually between 38 and 50 degrees) onto the deck, giving it a larger level to rotate the same slope of the deck. Many special longboard trucks also have an inverted padlock arrangement with a kingpin facing out.
Wheel
Skateboard wheels are usually made of polyurethane, and come in different sizes and different shapes according to different types of skating. The larger diameter (55-85 mm) scrolls faster, and moves more easily over cracks on the sidewalk and is better for skateboard transitions. The smaller diameter (48-54 mm) keeps the board closer to the ground, requiring less power to accelerate and produce a lower center of gravity that allows better response time, but also makes slower top speed and better for road skateboard. The wheels are also available in a variety of hardness usually measured on a "A" Shore durometer scale. Again like a car tire, the wheels range from very soft (about Shore A 75) to very hard (around Shore A 101). Since scale A stops at 100, each wheel labeled 101A or higher is more difficult, but do not use the appropriate durometer scale. Some wheel manufacturers now use the "B" or "D" scale, which has a wider and more accurate range of violence. Modern street skaters prefer medium-sized wheels (usually 51-54 mm), because small wheels with lighter trucks can make tricks like kicks and other flip tricks easier by keeping the skateboard's gravity center closer to the deck, making the deck easier spinning. The wheels are harder (A 100/A 101). Vertical ramp or "vert" skating requires larger wheels (usually 55-65 mm), as it involves higher speeds. Vert wheels are also usually slightly lighter (A 98/A 99), allowing them to maintain high speeds on the ramp without sliding. Slalom skating requires larger wheels (60-75 mm) to maintain the highest speed. They should also be gentle and have a better grip to make tight and frequent slalom turns. Even larger wheels are used in longboarding and downhill skateboards. Sizes range from 65 mm to 100 mm. The size of this extreme wheel almost always has a hard plastic core that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, because the large soft wheels allow for smooth and easy movement over all terrain.
Bearing
Each skateboard wheel is mounted on its axle through two bearings. With a few exceptions, the bearing is an industry standard "608" size, with a bore 8 mm (or 10mm depending on the shaft), an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, although silicon nitride, high-tech ceramics, are sometimes used. Many skateboard bearings are rated according to the ABEC scale. The scale starts with ABEC1 as the lowest, followed by 3, 5, 7, and 9. It is a common misconception that higher ABEC is better for skateboarding, because ABEC rating only measures tolerance, which does not always apply to skateboards. The bearing performance is determined by how well bearing maintenance is. Treatments on the pads include periodic cleaning and lubrication [1]. Unkempt bearings have very low performance and will soon need to be replaced. Cleaning pads are generally available on the market. ABEC rating does not specify the speed or durability of skateboard bearings. Specifically, the ABEC rating does not say anything about how well the bearings handle axial load (side to side), which is very severe in most skateboard applications. Many companies do not show ABEC ratings, such as Bones Bearings, which make special bearings for skateboards, often marketed as "Skate Rated". Each bearing usually contains 7 bearing balls of steel or ceramic, although other configurations are also used.
Hardware
Hardware installation is a set of eight UNF screws 10-32, usually Allen or Phillips heads, and nylon key matching. They are used to install trucks (and all types of stairs) to the boards. Some sets have one different colored bolts to show which side is the nose of the skateboard. Hardware is available in various sizes for truck installation with or without stairs.
Optional components
Rung/wedge
The stairs increase the space between the truck and the deck. This allows the truck to spin even further without causing wheel bites (when the wheel touches the deck and stops spinning). Wedges can be used to change the truck's turning characteristics.
Shock Bearing
Shock pads made of polyurethane and rubber. They are very similar to the rungs but vary in the fact that their sole purpose is to protect the board from the truck. Because trucks are metal and wooden boards, every time the board touches the ground after doing the trick, energy flows through the truck to the board - this causes the board to crack, split, or even break into two, and shock pads are made to prevent this.
BLOCK Riser
BLOCK riser is a functional version of a standard riser/wedge containing an open end that receives replaceable components such as GoPro Mount, Light Mount, Stash Drawer, Skate Tool, or Carry Strap & amp; Lock.
Rel/rib
The rail (or rib), is a narrow strip of plastic or metal attached under a long deck along the edges. They are used for additional grips up for grabs, and to improve sliding while protecting the deck graphs at the same time. The rails also give a more consistent feel to the slide, as regular skateboard slides will suffer from wear and tear of paint or varnish on the bottom of the board. Although rarely used again, they are useful for experienced skaters who are able to be contested.
Sliptape
Sliptape is a piece of self-adhesive plastic attached to the bottom of the deck. It helps protect the board graphics and allows the board to glide easier. Another name for this is everslick.
Lapper
Lapper is a plastic cover that is fastened to the rear truck and serves to protect the kingpin when grinding. It also prevents hang-ups by providing smoother transitions for trucks when crashing into obstructions or metal pipes or round bars.
Nose guard
The nose guard is a plastic bumper used to protect the skateboard front that was once popular but is now only commonly seen on older board models.
Tailor (skid a.k.a)
Dashed to the bottom of the skateboard tip, the tail guard (also known as the "slip plate") protects the tail end from the skid stop and other maneuvers that will erode the wood (commonly known as razors) and reduce the longevity of the tail. Usually made of plastic, it was very popular in the 80s but its use was quickly reduced by the appearance of a two-tailed board design, which became increasingly popular in the 90s.
Tail Devil
A "tailed demon" is a trigger device made of stone placed either on the tail or skateboard nose (or both) to create a triggering effect especially noticeable after dark when the tail or nose board is scratching the ground.
Copers
A half plastic tube that protects the truck's axle. In the 1980-85 period, shopping cart carts were cut by several people to serve as emergency coper.
Sublimated graphics
Sublimation (phase transition) is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. Sublimation is an endothermic phase transition occurring at the temperature and pressure below the triple point of a substance in the phase diagram. In this case, the ink is transferred to the base layer, fiberglass for example, through heat and pressure, the result is a full color graph that will not easily escape like a more general heat transfer. These applications are often found with bamboo boards and longboard composite construction where fiberglass can allow varying degrees of flexibility or stiffness depending on the journey you are looking for, cruising and engraving versus slalom and downhill.
