In 1978, Alan Gelfand, who was given his nickname "Ollie" by Scott Goodman, learned to perform no-handed aerials in bowls and pools using a gentle raising of the nose and scooping motion to keep the board with the feet.[2][3] There are numerous references to Alan Gelfand's Ollie with most notably pictures in the 1970s skateboarding magazine "Skateboarder".
The rider begins the ollie by crouching and jumping directly upward. As the rider begins to leap, instead of lifting the feet from the board, he/she "pops" the tail by striking it against the ground, which raises the board nose-first. Maintaining contact with the board, the rider lifts the front leg and bends the front ankle so that the outer or top side of the shoe slides towards the nose of the board. The friction between the shoe and the board's grip tape helps to guide and pull the board upward, while the rear foot only maintains slight contact with board to help guide it. When nearing the peak of the jump, the rider lifts the rear leg and pushes the front foot forward, which levels the board and keeps it in contact with the back foot.
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!
Maybe you're new to skateboarding. We have lots of complete skateboards or longboards to get you started. All of our skateboard and longboard completes come fully assembled, so you can hit the streets without any of the hassle—try an Enjoi skateboard complete or check out our selection of Sector 9 longboard and skateboard completes. Or maybe you're an experienced skater looking to update and customize your ride. You probably want to start with the perfect skateboard deck before you do anything else. We carry high-quality skate decks to keep you steady and balanced while you bomb, slide, and carve the streets. We also have a variety of longboard decks in stock if you're looking for a smooth ride for cruising or commuting.
Cruiser - The name says it all. If you are looking to cruise around town then this is the right complete skateboard for you. These decks vary in length from between 20 inches all the way up to about 40 inches. The wheel diameters usually start at about 55 millimeters and use a much softer urethane than the previous Popsicle decks. These also come with all of the above but the decks do not always need grip tape. Some of the decks are plastic or composite material with grooves or gripping built directly into the deck mold. 
There is no governing body that declares any regulations on what constitutes a skateboard or the parts from which it is assembled. Historically, the skateboard has conformed both to contemporary trends and to the ever-evolving array of stunts performed by riders/users, who require a certain functionality from the board. The board shape depends largely upon its desired function. Longboards are a type of skateboard with a longer wheelbase and larger, softer wheels.
Krown burst on to the skate scene back in 1996 with the idea to provide a high quality skateboard to the rider on a budget. Krown recognized a big gap between the $20 big box retail skateboard and the $150 professional grade skateboard. The boards at big box retail stores have plastic wheels and don’t even roll! Krown’s idea to bring a price-point skateboard to the market that actually functions as a skateboard has proven to be successful after more than 20 years. With more than 20 years of industry knowledge and knowhow, Krown is able to source the best parts at the best prices, which allows Krown to pass the savings on to the consumer. This expertise has allowed Krown to venture into the world of skateboards, longboards, helmets, pads, and even tools. Krown is the best place to start for beginner and intermediate riders!
