Kickbike
A kickbike (bikeboard, footbike, pedicycle) is a type of kick scooter (also referred to as a push-scooter or scooter) and is a human-powered street vehicle with a handlebar, deck, and wheels propelled by a rider pushing off the ground. The kickbike often has a large standard size bicycle front wheel and a much smaller rear wheel, which allows for a much faster ride. History The modern kickbike was developed in the early 1990s by Hannu Vierikko who was active at the time in kicksled racing. (A kicksled is a type of human powered sled that is in common use in Scandanavia.) In 1994 Vierikko founded Kickbike Worldwide in Finland to produce and market kickbikes. Use Amish communities also use kickbikes in preference to bicycles since bicycles involve gearing mechanics and can be seen as a source of vanity. Kickbikes can be used for dryland mushing, also called "dog scootering." Sport Some former world champions include Jan Vlasek and Alpo Kuusisto. Gallery File:Amish - Mode ...

Kick Scooter
A kick scooter (also referred to as a push-scooter or scooter) is a human-powered street vehicle with a handlebar, deck, and wheels propelled by a rider pushing off the ground with their leg. Today the most common scooters are made of aluminum, titanium, and steel. Some kick scooters made for younger children have 3 to 4 wheels (but most common ones have 2 wheels) and are made of plastic and do not fold. High-performance kickbikes are also made. Motorized scooters, historically powered by internal combustion engines, and more recently electric motors, are self-propelled kick scooters capable of speeds sometimes exceeding . Models and history Early scooters Kick scooters have been handmade in industrial urban areas in Europe and the United States since the 1920s or earlier, often as play items made for children to roam the streets. One common home-made version is made by attaching roller skate wheelsets to a board with some kind of handle, usually an old box. To turn, riders c ...

Kicksled
The kicksled or spark is a small sled consisting of a chair mounted on a pair of flexible metal runners that extend backward to about twice the chair's length. The sled is propelled by kicking (''sparka'' or ''sparke'' in the Scandinavian languages) the ground by foot. There is a handlebar attached to the top of the chair back. "Kicksled" is a direct translation of the Finnish word ''potkukelkka''. Estonian calls it either "pushsled" (''tõukekelk'') or "Finnish sled" (''Soome kelk''). Some other possible translations are "kicker" and "chair-sled". Design The typical adult sized sled has runners about long, spaced apart. The steel runner blades are about wide.The handlebars are about above ground. The kicksled is driven forward by the driver standing on one runner, kicking backwards on the ground with the other foot, hence the name. The flexibility of the runners allows the driver to steer the kicksled by twisting the handlebars. One can have a passenger or luggage o ...

Kerava
Kerava (; sv, Kervo) is a town and municipality within the Uusimaa region of Finland. The municipalities of Vantaa, Sipoo and Tuusula are adjacent to Kerava, which is part of the Helsinki metropolitan area. The town has a population of () and covers an area of of which is water. The population density is . Kerava is the 30th largest municipality in terms of population, but the 5th smallest municipality in terms of area in Finland (and the second smallest in the Uusimaa region after Kauniainen). However, it is also the third most densely populated area in the sub-region after Helsinki and Kauniainen. The municipality is unilingually Finnish. The Sinebrychoff brewery operations are based in Kerava. There is also a well-known prison in the town (''Keravan vankila''), which includes 94 places in the open prison ward. History Until the Middle Ages, Kerava was a wilderness, until two villages, Ylikerava ("Upper Kerava") and Alikerava ("Lower Kerava"), were created along the Kera ...

Wheeled Vehicles
A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel. Common examples are found in transport applications. A wheel reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity or by the application of another external force or torque. Using the wheel, Sumerians invented a device that spins clay as a potter shapes it into the desired object. Terminology The English word '' wheel'' comes from the Old English word , from Proto-Germanic , fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sports Equipment
Sports equipment, sporting equipment, also called sporting goods, are the tools, materials, apparel, and gear used to compete in a sport and varies depending on the sport. The equipment ranges from balls, nets, and protective gear like helmets. Sporting equipment can be used as protective gear or a tool used to help the athletes play the sport. Over time, sporting equipment has evolved because sports have started to require more protective gear to prevent injuries. Sporting equipment may be found in any department store or specific sporting equipment shops. History and development of sports Historically many sports players have developed their own sporting equipment over time. For instance, the use of a football dates back to ancient China, between 225 BC and 220 AD. As football remains the most popular sport in the 21st century, the material of the ball has completely changed over the centuries; from being made out of animal skin, to being lined with multiple layers of polyest ...

Balance Bicycle
A balance bicycle, run bike or no pedal bike or dandy horse is a training bicycle that helps children learn balance and steering. It has no foot pedals, no drivetrain, no chain, no gears, no gear shifters, no derailleurs, and no freewheel. Designs Balance bikes have been made out of both metal and wood. It can be a normal bicycle with pedals and related parts removed, or it can be purpose-built (especially for very small children, for whom normal bicycles are generally not available). Some are fitted with brakes and come with either air tires or solid foam tires. Most commercially available designs have flat handlebars. To function properly, a balance bicycle must be small enough for the rider to be able to walk the bicycle while sitting comfortably in the saddle, putting both feet flat on the ground. The rider first walks the bicycle while standing over the saddle, then while sitting in the saddle. Eventually, the rider feels comfortable enough to run and "scoot" while ridin ...

Mushing
Mushing is a sport or transport method powered by dogs. It includes carting, pulka, dog scootering, sled dog racing, skijoring, freighting, and weight pulling. More specifically, it implies the use of one or more dogs to pull a sled, most commonly a specialized type of dog sled on snow, or a rig on dry land. History The practice of using dogs to pull sleds dates back to at least 6000 BC. Remnants of sleds and harnesses has been found with canine remains in Siberia which carbon-dated to 7800–8000 years ago. Native American cultures also used dogs to pull loads. In 1534, Jacques Cartier discovered the Gaspé Peninsula and claimed the land in the name of Francis I of France. For the better part of a century the Iroquois and French clashed in a series of attacks and reprisals. For this reason, Samuel de Champlain arranged to have young French men live with the natives, to learn their language and customs and help the French adapt to life in North America. These men, known as (ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
