A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. It is a registered trademark of Segway Inc. It was brought to market in 2001 as the Segway HT, and then subsequently as the Segway PT.HT is an initialism for "human transporter" and PT for "personal transporter."
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a frame with a saddle, and has a pedal-driven direct-drive. A two speed hub is commercially available for faster unicycling. Unicycling is practiced professionally in circuses, by street performers, in festivals, and as a hobby. Unicycles have also been used to create new sports such as unicycle hockey. In recent years, unicycles have also been used in mountain unicycling, an activity similar to mountain biking or trials.
An electric unicycle is a self-balancing personal transporter with a single wheel. The rider controls speed by leaning forwards or backwards, and steers by twisting or tilting the unit side to side. The self-balancing mechanism uses accelerometers and gyroscopes. Most manufacturers of EUCs are based out of China, including Segway, Inmotion, Kingsong, Begode, and Leaperkim.
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.
Longboarding is a variation of skateboarding typified by the use of longer boards ("decks") with longer wheelbases and softer wheels. While longboards vary widely in shape and size, compared to street skateboards longboards are designed to be more stable at speed and to have more traction due to larger wheel sizes and softer wheel durometers. While standard street skateboards may typically be between 28 and 34 inches long, longboards can range anywhere from 32 to 50 inches in length. Ride characteristics of longboards generally differ from that of street skateboards due to the use of specialized longboard trucks that have different properties than those typically used with skateboards; while street skateboards use "traditional kingpin" (TKP) trucks that are optimized for tight turning radii, ollie and flip tricks, slides, grinds, and transition skating, longboards are typically paired with "reverse kingpin" (RKP) trucks that are designed for increased stability at higher speeds, more "surfy" carving characteristics, and/or greater ride comfort for commuting over longer distances.
The Trikke is a chainless, pedalless, personal vehicle with a three-wheel frame. The rider stands on two foot platforms above the two rear wheels and steers the vehicle with handlebars attached to the lone front wheel. The cambering system is designed to provide a stable, three-point platform that lets the rider lean into turns while all three wheels remain in contact with the ground. There are several variations of the Trikke, from body-powered fitness machines, to battery-powered transportation and personal mobility vehicles.
The Honda XR series is a range of four-stroke off-road motorcycles that were designed in Japan but assembled all over the world.
The Saturn Aura is a four-door, five-passenger front engine/front-wheel drive mid-sized sedan manufactured and marketed by GM's Saturn subsidiary over a single generation from 2006 to 2009. The car launched one year before the seventh generation Chevrolet Malibu, its most closely related platform companion.
Speed wobble is a rapid side-to-side shaking of a vehicle's wheel(s) that occurs at high speeds and can lead to loss of control. It presents as a quick (4–10 Hz) oscillation of primarily the steerable wheel(s), and is caused by a combination of factors, including initial disturbances and insufficient damping, which can create a resonance effect. Initially, the rest of the vehicle remains mostly unaffected, until translated into a vehicle yaw oscillation of increasing amplitude, producing loss of control.
Venturi is a Monaco-based automotive manufacturer. Founded in 1984 by French engineers Claude Poiraud and Gérard Godfroy as MVS. Venturi operated for nearly sixteen years, before declaring bankruptcy in 2000. The same year, Monegasque Gildo Pallanca Pastor purchased Venturi, and decided to focus on electric-powered motors.
A kick 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 and are made of plastic and do not fold. High-performance kickbikes are also made. A company that had once made the Razor Scooters revitalized the design in the mid-nineties and early two-thousands. Three-wheel models where the frame forks into two decks are known as Y scooters or trikkes.
A motorized scooter is a stand-up scooter powered by either a small internal combustion engine or electric hub motor in its front and/or rear wheel. Classified as a form of micromobility, they are generally designed with a large center deck on which the rider stands. The first motorized scooter was manufactured by Autoped in 1915.
A caster board, vigorboard or waveboard is a two-wheeled, human-powered land vehicle. Other names are J-board and RipStik, both of which are derived from commercial brands.
Flowriding is a late 20th century alternative boardsport incorporating elements of surfing, bodyboarding, skateboarding, skimboarding, snowboarding and wakeboarding.
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 KTM X-Bow is an ultra-light sports car manufactured by Austrian automotive manufacturer KTM, a company known for their production of motorcycles. The X-Bow was the first mass-produced car in their product range and was unveiled and launched at the Geneva Motor Show in 2008. The X-Bow road car was developed in collaboration with KISKA, Audi, and Dallara.
An electric skateboard is a personal transporter based on a skateboard. The speed is usually controlled by a wireless hand-held throttle remote, or rider body weight-shifting between front of the board for forward motion and rear for braking. As for the direction of travel to the right or left, it is adjusted by tilting the board to one side or the other. The classification of electric skateboards and legality of their use on roads or pavements varies between countries.
A self-balancing scooter 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.
Boosted was an American manufacturer of electric skateboards and electric scooters based in Mountain View, California.
A personal transporter is any of a class of compact, mostly recent, motorised micromobility vehicle for transporting an individual at speeds that do not normally exceed 25 km/h (16 mph). They include electric skateboards, kick scooters, self-balancing unicycles and Segways, as well as gasoline-fueled motorised scooters or skateboards, typically using two-stroke engines of less than 49 cc (3.0 cu in) displacement. Many newer versions use recent advances in vehicle battery and motor-control technologies. They are growing in popularity, and legislators are in the process of determining how these devices should be classified, regulated and accommodated during a period of rapid innovation.
