There are actually several types of skateboards but the most common ones are the longboard, cruiser, and carve skateboards. A longboard is usually at least 33 inches. It is a great mode of transportation and works well for cruising around. The cruiser also works well as a mode of transportation but many consider it more beneficial as it has a shorter skateboard, which promotes ease in transporting around.

The skateboard has a solid and stiff mini-deck, which is around 22 inches and constructed out of 100% plastic material. Such deck is very lightweight. It is only four pounds but you have an assurance that it can handle up to 198 lbs. of weight. You will also fall in love with the board as it comes in 23 graphics and colors, so picking a favorite is much easier.

To summarize, a skateboarder's feet need to do two things successfully to complete an ollie. They need to provide a changing force to move the board correctly (so that the combined force of gravity and the skater's feet add up to the green arrows above), and they need to provide different amounts of force with each foot (shown by the red and blue arrows above) to steer and turn the board into the right orientation.
Now, I might not be able to skate to save my life, but I can do a little physics. So here's a thought - maybe I can use physics to learn how to do an ollie. Here's the plan. I'm going to open up the above video of skateboarder Adam Shomsky doing an ollie, filmed in glorious 1000 frames-per-second slow motion, and analyze it in the open source physics video analysis tool Tracker.
Get used to sliding your front foot up the length of the board. Once you’ve perfected lifting the front of the board up, use your back foot to hold the board in that position. Slide your front foot up the board towards the front, rotating it as you do so. The side of your foot just below the toes should grate along the deck of your board until it reaches the top.[5]
EXPERIENCED SKATER! This board is amazing for the price! (notice i said FOR THE PRICE) At the time of this review, the board was $44.40 and for that price the board i got was phenomenal. It is a 7-ply deck with aluminum trucks (havent figured out the bearings but they definitely feel like the abec 5 they claim to be). The trucks arent the best quality out there and the board can be a little thinner (maybe 5-ply) but the overall board is amazing. There are only two complaints. The hole in the wheels is a tiny TINY TIIINYYY bit off center, but nothing that cant be fixed with a new set. I can see what another review said by it not coming assembled, as a couple of the bolts on the wheels are a little loose, but the board does come assembled.
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.
4 amazing skateboards in one nice lot. 1. 1990's Tony Hawk Conplete Skateboard, original falcon 3 design. With Rekon trucks and firelite classic wheels. 2. Sk8mafia Lucero deck. Signed by John Lucero. Brand new deck. 3. 1031 deck signed by entire team on a brand new creepy crawl deck. 4. Brand new super rare Big Mess deck with Blast design. This deck is extremely rare and is a must have for any collector. Both the signed decks are personalized to a guy named Jason that owned a skate shop here in Grant's Pass Or. Those guys were on his wall for a long time before he went out of business. If you have any questions or concerns please let me know. Thanks for looking. Steve
