Human-powered Vehicles
Human-powered land vehicles are land vehicles propelled over ground by human power, The main ways to support the weight of a human-powered land vehicle and its contents above the ground are rolling contact; sliding contact; intermittent contact; no contact at all as with anything carried; or some combination of the above. The main methods of using human power to propel a land vehicle are some kind of drivetrain; pushing laterally against the ground with a wheel, skate, or ski that simultaneously moves forward; by pushing against the ground directly with an appendage opposite to the direction of travel; or by propeller. Human-powered land vehicles can be propelled by persons riding in the vehicle or by persons walking or running and not supported by the vehicle. Many human-powered land vehicles can also be gravity-powered land vehicles, and vice versa, although some of the latter are quite awkward to use as the former. For example: street luges, gravity racers, and snow boards. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roller Ski
Roller skiing is an off-snow equivalent to cross-country skiing. Roller skis have wheels on their ends and are used on a hard surface to emulate .Bryhn, Rolf and Knut Are Tvedt (eds.): ''Kunnskapsforlagets idrettsleksikon''. (Norwegian Encyclopedia of Sports). Oslo: Kunnskapsforlaget, 1990. The skiing techniques used are very similar to techniques used in cross-country skiing on snow. First created as a summer training exercise, roller skiing grew into a competition#Sports, competitive sport in its own right. Annual championships are held in various locations around the world. Most, if not all, national cross-country ski teams around the world roller ski during the off-season for specific physical training simulating winter skiing. In Norway, separate roller ski facilities have been constructed to allow exercise off public roads. History The first roller skis were built in the mid-1930s in Italy and North Europe. In the early 1950s, when cross-country skiing started to evolve to a ... [...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] |
Penny Board
A Penny board is a type of skateboard that is characterized by a short and narrow plastic deck. Although such skateboards were first manufactured during the 1970s, their name and contemporary popularity come from the Australian brand Penny Skateboards, founded in 2010. The company's name has since been widely genericized to describe all small plastic skateboards. History The first line of plastic skateboards was launched in the 1970s by Larry Stevenson for his brand. Greentech also began to manufacture plastic skateboards.Courtney RubinPenny Skateboards Find a Niche ''Nytimes.com'', 22 July 2015 These plastic skateboards were widely popular during the early 1970s, although the era's professional skaters still shunned them in favor of wooden boards. By 1978, laminated wooden decks had become the industry standard. Ben Mackay created the Penny board in 2010, from which the brand Penny Skateboards was born. MacKay named the brand for his sister, Penny. The idea behind the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longboard (skateboard)
A longboard is a type of skateboard typified by longer decks and wheelbases, larger-diameter and softer (lower-durometer) wheels, and often lower riding height compared to street skateboards, though there is wide variation in the geometry and construction of longboards. Among the earliest types of skateboards, longboards were inspired by surfing, with early longboards drawing from the design of surfboards, resembling and mimicking the motion of riding a surfboard, but adapted to riding on streets in a practice known as ''sidewalk surfing''. Available in a wide variety of shapes, longboards are typically designed and optimized for ''cruising'' (covering distances at moderate speeds), commuting (as a practical means of personal transport), and ''downhill (racing)''. The act of riding on a longboard in general is known as longboarding, which can also include more specialized forms such as longboard ''dancing'', which involves stepping up and down a board and other movements and mot ...

Skateboard
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] |
Shopping Trolley (caddy)
A shopping caddy or shopping trolley is a large bag on wheels, used for carrying a large amount of shopping home on foot. The bag is typically made from a waterproof fabric, and wicker basket designs are also sold. The trolleys commonly have two parallel wheels on a hand truck style frame (with a handle and stand), but some designs have four or six wheels. In some countries the trolleys are traditionally regarded as being used by pensioner-age women, with granny cart being an American slang term for the four-wheeled wire-framed trolleys, which are sometimes used without a bag. In the UK they are known as a granny trolley and are available in foldable versions. In 2023, the ''Farino Carrier'' with rollerblade wheels was pitched as a unique new product on Dragons' Den.

Stroller
Various methods of transporting children have been used in different cultures and times. These methods include baby carriages (prams in British English), infant car seats, portable bassinets (carrycots), strollers (pushchairs), slings, backpacks, baskets and bicycle carriers. The large, heavy prams (short for perambulator), which had become popular during the Victorian era, were replaced by lighter designs during the latter half of the 1900s. Baskets, slings and backpacks Infant carrying likely emerged early in human evolution as the emergence of bipedalism would have necessitated some means of carrying babies who could no longer cling to their mothers and/or simply sit on top of their mother's back. On-the-body carriers are designed in various forms such as baby sling, backpack carriers, and soft front or hip carriers, with varying materials and degrees of rigidity, decoration, support and confinement of the child. Slings, soft front carriers, and "baby carriages" are typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rickshaw
Rickshaw originally denoted a pulled rickshaw, which is a two- or three-wheeled cart generally pulled by one person carrying one passenger. The first known use of the term was in 1879. Over time, cycle rickshaws (also known as pedicabs or trishaws), auto rickshaws, and electric rickshaws were invented, and have replaced the original pulled rickshaws, with a few exceptions for their use in tourism. Pulled rickshaws created a popular form of transportation, and a source of employment for male labourers, within Asian cities in the 19th century. Their appearance was related to newly acquired knowledge of ball-bearing systems. Their popularity declined as cars, trains and other forms of transportation became widely available. Auto rickshaws are becoming more popular in some cities in the 21st century as an alternative to taxis because of their low cost of hire. Bangladesh holds the record of hosting highest number of rickshaws in the world with 40,000 rickshaws operating in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Scooter
In geometry, a square is a regular quadrilateral. It has four straight sides of equal length and four equal angles. Squares are special cases of rectangles, which have four equal angles, and of rhombuses, which have four equal sides. As with all rectangles, a square's angles are right angles (90 degrees, or /2 radians), making adjacent sides perpendicular. The area of a square is the side length multiplied by itself, and so in algebra, multiplying a number by itself is called squaring. Equal squares can tile the plane edge-to-edge in the square tiling. Square tilings are ubiquitous in tiled floors and walls, graph paper, image pixels, and game boards. Square shapes are also often seen in building floor plans, origami paper, food servings, in graphic design and heraldry, and in instant photos and fine art. The formula for the area of a square forms the basis of the calculation of area and motivates the search for methods for squaring the circle by compass and straightedge, now ...
