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.
Land at the same time – Again, this is probably silly to repeat, but you’d be surprised to find out how many people execute a successful jump, and then throw their hands up in the air to celebrate their new-found triumph, and forget the most important part: landing. The best position for your feet to be in is as close to the trucks as possible. Don’t land too close to the nose or tail, or you could end up breaking off those the board itself. Also, remember to bend your knees to absorb the jump. Don’t want to land straight-legged: that’s how kneecaps are destroyed.
The Bamboo Mini Cruiser deck is 6-inches-by-22.5-inches with that classic cruiser shape. The board is made with 6-ply bamboo and maple construction, which is lightweight, flexible and eco-friendly. Bamboo Skateboards claims this board has a turning radius not seen in most mini decks. The small, blank deck is heavy duty and durable in a way not all mini cruisers are. The non-carbonized board is ready for you to slap on the grip tape and artwork you want and then get riding.
In fact, we can work out how you need to steer the skateboard. Tracker has a nice feature that we'll call 'force arrows'. These arrows show you how much force acts on an object at every instant, and in which direction the force acts. So for example, if you were to kick a ball into the air, while the ball was mid-flight, this arrow would always point down and be the same length, even though the ball is moving forward. That's because the only force acting on the ball is gravity, which pulls it straight down, and acts with a constant strength. (For those of you who've studied physics, these arrows denote the acceleration of the center of mass, which by Newton's second law is proportional to the net force acting on the skateboard.)
In the case that you didn't gave up after a hundred over tries, you'll start to develop a reaction to landing it. After a few hundred more tries, you'll feel you are getting off the ground and getting little air. And once you reach the thousandth try, you'll already be doing it whilst rolling and the next thousandth tries will be spent on clearing small cracks n obstacles and working towards ollieng up bigger obstacles n up ledges.
This is how I learned how to ollie. Place your skateboard next to a curb, right up against it. This will help keep your board from rolling. Next, do everything that I just described, but don’t worry about what your board does. Just do it, and land up on top of the curb, on the sidewalk. Don’t stress about whether the skateboard will be there, or if you will get hurt – just go through the motions of ollying up the curb. If you do it right, the skateboard will be there. If you do it wrong, you’ll probably just land on your feet on the sidewalk. Here’s the key – just do it and expect it to work. Your body understands what you are trying to do, and the less you stress, the more it can kick in and fill in the blanks.

The KPC Series Pro Skateboard measures 8.0” x 32”. This is a common width most often associated with pro skateboarders. Wider and stronger than the rookies, this model is the perfect size for someone who is better at skating and looking for an upgrade from the rookie models. The pro features a modern concave which allows for not only comfort, but more pop making it easier to learn tricks.
For sale I have a Powell peralta old school ripper complete red and black with 169mm independent blackout trucks blue cambria 3md 62mm wheels and bones reds bearings The deck has only been skated twice with minor scrapes on the tail and wheel wells I added the independent blackout 69mm trucks and the Cambria wheels im selling it because I’m moving in a different direction I’m building a longboard for myself for this summer anyway the deck is a reissue ripper you can’t get it anymore great overall skater very durable

Skateboarding is all about creativity and finding new challenges. A great way to explore skateboarding is to ride different shaped boards, wider trucks, and different size wheels. As you progress and start to ride new terrain and skate different kinds of spots, you may find one wheel size or board shape works better for you than another. There’s no wrong or right anything. There are no rules. Except for maybe one, and that is to keep skating. Skate as often as you can. Never is this more true than in the beginning while you’re developing your style and fundamentals.
The Landwalker 22″ Complete Skateboard has a sturdy 7 layer Canadian maple deck. It’s best for downhill, U table and slider because of its enormous stability. This board is best for teens and adults. It comes with Abec 7″ Bearings, PU wheels, Black Grip Tape, and hardware. It measures 79 x 20 x 10 cm. This board is an awesome gift for Christmas or Halloween.
The wheels are also impressive. Unlike some other skateboards that have wheels that are quite stiff, causing them to feel like they will lock up when you ride on them, the wheels in this complete skateboard for beginners are smooth and comfortable. These are also easily controllable, so rest assured that they offer a smooth and friction-free glide.
