are faster than a folding scooter and more convenient than a utility bicycle. Some are made for off-road use and are described as mountain scooters. In addition to commuting, sports competition, and off-road use, large wheel scooters are a favorite for dog scootering, an activity in which single or team dogs, such as huskies, pull a scooter and its rider in the same way that a sled is pulled across snow. Some Amish are not allowed to ride bicycles, so they ride scooters instead. Today, variations on the kicksled with scooter design features are also available, such as the Kickspark. Kickbike The development of the kickbike in Finland in 1994 changed the way scooters are viewed. The Kickbike has a large standard size bicycle front wheel and a much smaller rear wheel, which allows for a much faster ride. The Footbike Eurocup has been held since 2001. Folding scooters In 1990, a foldable aluminium scooter with inline skates wheels was created by Wim Ouboter of Micro Mobility Systems in Switzerland. The scooter was sold as "Micro Skate Scooter," "Razor," and "JDBUG/JDRAZOR MS-130A". The Razor was introduced to Japan in 1999, with many early adopters being young Japanese who used it for portable transport. It later became a worldwide fad and these small scooters also became popular toys for children. TurboAnt's folding scooters are known for their detachable battery designs. Its electric scooters have a range between 18 to 30 miles. Pro scooters Kick scooters used for extreme sport stunts and tricks and made to withstand stresses and frustrations, are called pro scooters. Numerous brands specialize in stunt scooters and accessories including lightweight and high strength parts, helmets, pads, ramps, grind wax, griptape and clothing. Three wheels Three-wheeled scooters similar to tricycles have been produced for little children. In 1999, Micro Mobility Systems and K2 Sports produced a reverse-three-wheeled scooter called "Kickboard". Micro also produced the Kickboard-like children's scooters "Mini Micro" and "Maxi Micro". The reverse design inherently provides greater stability than the standard: a standing person will tend to stand at the front of a scooter rather than at the back. However, the steering geometry is inherently weak and requires design adaptation to improve its response. An example is the Mini Micro, which uses a spring-loaded system to translate lateral force on the handbars (child leaning) into turning motion on the wheels, referred by its makers as "lean and steer".
