After you’ve properly applied a burst of force to the tail, the top-side of your front foot’s toe should start dragging up your board almost automatically. Eventually, the higher you are able to bring your front foot during lift will determine the apex of your ollie, so work gradually towards lifting your front foot as high as your body allows. Skateboarders who record the highest ollies usually (somehow manage to!) bring their feet higher than their hips!
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.
If you’ve ever watched a skateboarder roll down the street and then all of a sudden pop into the air on a skateboard, you’re probably wondering the same question a lot of people do: how on earth do they do that? It almost seems magical how they just seem to explode off the ground, and then just kind of float. Skateboarder, meet, the ollie. It’s not in the category of “easy skateboard tricks,” but if you learn how to ollie, you’re well on your way to fame and fortune as a professional skater.
My fiancee purchased this via my account and he says that it has good concave shape and pop.Assembling was fairly simple, easier if you have a box cutter on hand to help with laying the grip tape. The deck was the best part but the bearings were good too. He thought the bushings were the worst, after about two hours of skating, both bushings were crushed and stuck in one direction. He's been skating for almost 13 years. Hope this helps!
A rushed take-off might be the problem here. Steps 2-4 of this trick tip could help you out. In order to make your feet “stick” to the board, you have to do the movement fluidly. But don’t stress yourself out! You should rather start with some preliminary exercises until you feel safe while ollieing. It is also important to pull your foot up to your board’s nose in a straight manner to prevent it from spinning.
