Invented in the late 1970s by Alan "Ollie" Gelfand, the ollie has become a skateboarding fundamental, the basis for many other more complicated tricks. In its simplest form, the ollie is a jumping technique that allows skaters to hop over obstacles and onto curbs, etc. What's so amazing about the ollie is the way the skateboard seems to stick to the skater's feet in midair. Seeing pictures of skaters performing soaring 4-foot ollies, many people assume that the board is somehow attached to the skater's feet. It's not. What's even more amazing about the ollie is that to get the skateboard to jump up, the skater pushes down on the board! The secret to this paradoxical maneuver is rotation around multiple axes. Let's take a closer look.
Sizing plays an important role in the performance of any deck. A large majority range in size from 7.75" to 8.5" in width. These will provide a great platform for shredding any obstacle and will excel in street and skatepark environments alike. For those who prefer a smaller board, decks are offered down to 7.5" in width- benefiting people with smaller feet or the technical skater. Conversely, those looking for a wider board will enjoy our selection ranging up to 8.9" wide. Larger decks will accommodate those with very large feet, as well as offer an amazing experience for cruising and shredding large ramps and transitions.
The laws for skateboarding helmets vary from state to state. Many states require that skaters wear a helmet under a certain age, and some states like California make all skaters under 18 wear a CPSC Certified helmet at all times. CSPC skateboard helmets usually have an EPS protective liner that meets the safety standards for skateboarding. Make sure you check your state's regulations before ordering.
The longboard, a common variant of the skateboard, is used for higher speed and rough surface boarding, and they are much more expensive. "Old school" boards (those made in the 1970s–80s or modern boards that mimic their shape) are generally wider and often have only one kicktail. Variants of the 1970s often have little or no concavity, whereas 1980s models have deeper concavities and steeper kicktails.[7]
The wheels of a skateboard are usually made of polyurethane, and come in many different sizes and shapes to suit different types of skating. Larger diameters (55–85 mm) roll faster, and move more easily over cracks in pavement and are better for transition skateboarding. Smaller diameters (48–54 mm) keep the board closer to the ground, require less force to accelerate and produce a lower center of gravity which allows for a better response time, but also make for a slower top speed and are better for street skateboarding. Wheels also are available in a variety of hardnesses usually measured on the Shore durometer "A" scale. Again like car tires, wheels range from the very soft (about Shore A 75) to the very hard (about Shore A 101). As the A scale stops at 100, any wheels labeled 101A or higher are harder, but do not use the appropriate durometer scale. Some wheel manufacturers now use the "B" or "D" scales, which have a larger and more accurate range of hardness. Modern street skaters prefer medium-sized wheels (usually 51–54 mm), as small wheels with lighter trucks can make tricks like kickflips and other flip tricks easier by keeping the center of gravity of the skateboard closer to the deck, thus making the deck easier to spin. Street 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 softer (A 98/ A 99), allowing them to maintain high speed on ramps without sliding. Slalom skating requires even larger wheels (60–75 mm) to sustain the highest speeds possible. They also need to be soft and have better grip to make the tight and frequent turns in slalom racing. Even larger wheels are used in longboarding and downhill skateboarding. Sizes range from 65 mm to 100 mm. These extreme sizes of wheels almost always have cores of hard plastic that can be made thinner and lighter than a solid polyurethane wheel. They are often used by skateboard videographers as well, as the large soft wheels allow for smooth and easy movement over any terrain.

Shock pads are made of polyurethane and rubber. They are very similar to risers but vary in the fact that their sole purpose is to cushion the board from the trucks. Since the trucks are metal and the board wood, whenever the board hits the ground after doing a trick, the energy goes through the truck to the board ─ this has caused boards to crack, split, or even break in half, and shock pads were created to prevent this.

In general an axle width should be chosen that is close to the width of the deck it will be used with.[8] For example, a 7.75" wide deck will usually be fitted with trucks that have axles between 7.5" wide and 8.0" wide. (Standard truck axle nut size is 5/16"-24tpi UNF, and the thinner "jam" style with an optional nylon lock.) Trucks that are too wide can make doing tricks difficult and can cause the wheels to get in the way when the skateboard is being ridden. Trucks that are too small can be hard to maintain stability and can cause wheel bite to occur when turning.

Almost is proud to announce a collaboration with Skateistan, the award-winning non-profit organization empowering children and youth through skateboarding and education. They recently launched a new Skate School in Phnom Penh, Cambodia on Friday (February 23rd, 2018). Over 100 children celebrated alongside special guests from around the world, including Almost flow skater Sky Brown. 
After that I went to my regular Olley spot to practice, fell so hard three times. My legs were so fucked up from the day before. Now I feel like shit because I had problem with a 20cm ledge I landed at least 100 times up and down yesterday. I’m even capable of 50cm ledges at slow speed, but I only get the front wheel and the board up so I have to put pressure on the nose to get it all the way up.
Also called the mounting hardware, the skateboard hardware is useful in connecting the trucks to the deck. Every truck is actually in need of 4 bolts and locknuts. If you are planning to buy hardware for your custom skateboard, then note that they are often sold in sets composed of 8 parts, though it is also possible for you to buy individual parts separately when required.
Here we have an original Z Jimmy Plumer model. It has some handling scuffing from being around for several decades, but displays great. Grip has no holes at trucks which leads me to believe it’s never had any mounted. This is one heavy fiberglass mamma jamma. Get this piece of history at a fair price. I will throw in free priority insured shipping for the con us. Everywhere else at actual cost. Thanks for looking.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
