Caster Board
A caster board, vigorboard or waveboard is a two-wheeled, human-powered land vehicle. Other names are J-board and RipStik (sometimes written ripstick or rip stick), both of which are derived from commercial brands. A caster board has two narrow platforms known as "decks" that are joined by a torsion bar, which consists of a metal beam, usually coated by rubber, that houses a strong spring. One polyurethane wheel is mounted to each deck with a caster so that each wheel can steer independently, and each caster has a steering axis that is tilted about 30° back from the vertical. Origins The original caster board was called an "EssBoard"—the brainchild of South Korean inventor Singi Kang (KANG Shin Ki), who came up with this radical redesign of the skateboard as early as 2002. His initial patent application that year (“The skateboard that go forward by swing”) was revised and resubmitted (“Skateboard with direction-caster”), with approval following in August 2003. Mea ...

Skateboarding Equipment
Skateboarding is an action sport that involves riding and performing tricks using a skateboard, as well as a recreational activity, an art form, an entertainment industry job, and a method of transportation. Originating in the United States, skateboarding has been shaped and influenced by many skateboarders throughout the years. A 2009 report found that the skateboarding market is worth an estimated $4.8 billion in annual revenue, with 11.08 million active skateboarders in the world. In 2016, it was announced that skateboarding would be represented at the 2020 Summer Olympics in Tokyo, for both male and female teams. Skateboarding made its Olympic debut in 2020 and was included in the 2024 games. Since the 1970s, skateparks have been constructed specifically for use by skateboarders, freestyle BMXers, aggressive skaters, and more recently, scooters. However, skateboarding has become controversial in areas in which the activity, although legal, has damaged curbs, stoneworks ...

Skateboards
A skateboard is a type of sports equipment used for skateboarding. It is usually made of a specially designed 7–8-ply maple plywood deck and has polyurethane wheels attached to the underside by a pair of skateboarding trucks. The skateboard moves by pushing with one foot while the other foot remains balanced on the board, or by Pump (skateboarding), pumping one's legs in structures such as a bowl or half pipe. A skateboard can also be used by standing on the deck while on a downward slope and allowing gravity to propel the board and the rider. If the rider's leading foot is their left foot, they are said to ride "regular". Conversely, they are said to ride "goofy" if their leading foot is their right foot. The two main types of skateboards are the longboard and shortboard. The shape of the board is also important: the skateboard must be concaved to perform tricks. History Skateboarding, as it exists today, was probably born sometime in the late 1940s, or early 1950s, when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Snowboard
Snowboards are boards where the user places both feet, usually secured, to the same board. The board itself is wider than most skis, with the ability to glide on snow."snowboarding." Dictionary.com Unabridged (v 1.1). Random House, Inc. 17 Mar. 2009. . Snowboards widths are between 6 and 12 inches or 15 to 30 centimeters. Snowboards are differentiated from monoskis by the stance of the user. In monoskiing, the user stands with feet inline with direction of travel (facing tip of monoski/downhill) (parallel to long axis of board), whereas in snowboarding, users stand with feet transverse (more or less) to the longitude of the board. Users of such equipment may be referred to as ''snowboarder''s. ''Commercial snowboards'' generally require extra equipment, such as bindings and special boots which help secure both feet of a snowboarder, who generally ride in an upright position. These types of boards are commonly used by people at ski hills, mountains, backcountry, or resorts for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snakeboard
A Snakeboard, also known as a Streetboard, or Pivotboard is a type of skateboard invented in South Africa in 1989 by James Fisher, Simon King and Oliver Macleod Smith. The concept was to fuse the original skateboard with elements of snowboarding and surfing to create a fun riding experience. The first prototype was constructed using two square wooden boards, an old roller skate chopped in half, and a piece of plumbing pipe to join them together. Many variants were tried before manufacturing began. The first boards to be mass-produced were made from a strong plastic nylon known as Zytel ST801. Performance The rider of a snakeboard stands with one foot on each footplate (the feet are usually fixed to the board using bindings) and, by moving their feet in and out in conjunction with the shoulders and hips, is able to propel the board in any direction using only body weight. This transfer of energy is called nonholonomic locomotion. The board moves in a motion similar to that of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Self-balancing Scooter
A self-balancing scooter (also hoverboard, self-balancing board, electric scooter board, or swegway) is a self-balancing personal transporter consisting of two motorized wheels connected to a pair of articulated pads on which the rider places their feet. The rider controls the speed by leaning forward or backward, and direction of travel by twisting the pads. Invented in its current form in early 2013, the device is the subject of complex patent infringement, patent disputes. Volume manufacture started in China in 2014 and early units were prone to catching fire due to an overheating battery which resulted in product recalls in 2016, including over 500,000 units sold in the United States by eight manufacturers. There have been 23 official recalls since 2016, affecting around 1,115,200 units in total. History Shane Chen, a China, Chinese businessman and founder of Inventist filed a patent for a device of this type in February 2013 and launched a Kickstarter fund-raising campaign ...

Freeline Skates
Freeskates consist of two separate metal or wooden plates with two wheels attached at an angle. People call it freeskating, freeline skating, or drift skating. History They were developed in 2003 in San Francisco by Ryan Farrelly. Farrelly founded a company called Freeline that has since gone out of business. Freeskating is practiced around the world. In 2015, former members of the original brand (Freeline) came together to create JMKRIDE. Based in San Diego, California JMKRIDE aimed to revive the sport they loved so much. The sport was rebranded to be called "freeskating" to reach worldwide riders. The Freeskates rider is positioned sideways and move their feet back-and-forth in a motion called pumping to accelerate. Pumping acceleration is enhanced by swinging of arms and hips, providing a counterweight to push the skates. To move forward, the two feet move in a sinusoidal motion with slightly different phase. To turn left or right, the rider would part the feet of their toes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truancy
Truancy is any intentional, unjustified, unauthorized, or illegal absence from compulsory education. It is a deliberate absence by a student's own free will and usually does not refer to legitimate excused absences, such as ones related to medical conditions. Truancy is usually explicitly defined in the school's handbook of policies and procedures. Attending school but not going to class is called ''internal truancy''. Some children whose parents claim to homeschool have also been found truant in the United States. In many countries, truancy is criminalized by law as either a criminal or a civil offense, and authorities can prosecute truant students ( under the age of 18), their parents, or both. Some countries, like Canada or Australia, reserve fines for truant minors and allow for their detainment (but not arrest) while skipping school. In Russia, Germany and some parts of the U.S. police officers even have the power to handcuff and arrest truant minors on the streets during ...
