Mounting hardware is a set of eight 10-32 UNF bolts, usually an Allen or Phillips head, and matching nylon locknuts. They are used to attach the trucks (and any type of risers) to the board. Some sets have one different colored bolt to show which side is the nose of the skateboard. Hardware is available in various lengths for mounting trucks with or without risers.
There are other types of ollies that you can do either alongside or combine with the ones listed above, like the tailgrab, indy grab, melon grab, stalefish, tweak, and dolphin nose. All of those skateboard tricks are performed more or less how they sound, but you might want to watch some videos on youtube to see a pro in action (as well as awesome cat videos).
In general an axle width should be chosen that is close to the width of the deck it will be used with. 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.
Pop in your earbuds and head to the skate park with a skateboard that rolls through impressive stunts with ease. Most skateboards for sale offer strong wood decks that create a stable feel beneath your feet as you work on your grind and backslide techniques, but models with polypropylene construction offer a lightweight alternative with plenty of toughness. Try a surfboard-inspired design to cruise the streets like you'd ride a wave, or select a drop-through deck for smooth cruising. Grip tape promotes sure footing that helps you ride with confidence, but always put safety first - wear a skate helmet and skate pads from our Skateboard Shop for protection against mid-move falls.
