Monocycle
A monowheel, or uniwheel, is a one-wheeled single-track vehicle similar to a unicycle. Hand-cranked and pedal-powered monowheels were patented and built in the late 19th century; most built in the 20th and 21st century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. The world speed record for a motorized monowheel is 98.464 km/h (61.18 mph). Stability Similar to bicycles, monowheels are stable in the direction of travel, but have limited horizontal stability. This is in contrast to unicycles which are unstable in both directions. Monowheels have also been found to have a lower speed required for stability when compared to unicycles. A monowheel remains upright due to gyroscopic effects, but its lack of stability makes it highly dependent on forward momentum and the balance of the rider, who must maintain stability while steering.

Unicycle
A unicycle is a vehicle that touches the ground with only one wheel. The most common variation has a bicycle frame, frame with a bicycle saddle, saddle, and has a human-powered vehicle, pedal-driven direct-drive mechanism, direct-drive. A two speed hub is commercially available for faster unicycling. Unicycling is practiced professionally in circuses, by street performance, 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 Mountain bike trials, trials. History US patents for single-wheeled 'velocipedes' were published in 1869 by Frederick Myers and in 1881 by Battista Scuri. Unicycle design has developed since the Penny Farthing and later the advent of the first unicycle into many variations including: the seatless unicycle ("ultimate wheel") and the tall ("giraffe") unicycle.

Twisted Metal
''Twisted Metal'' is a series of vehicular combat video games published by Sony Computer Entertainment, and developed by various companies. The series has appeared on the PlayStation, PlayStation 2, PlayStation Portable and PlayStation 3. As of October 31, 2000, the series has sold 5 million copies. Several of the games in the series were re-released as part of the Sony Greatest Hits program. The original game and its first sequel were also released for the PC. Overview In concept, ''Twisted Metal'' is a demolition derby that emphasizes the usage of ballistic projectiles, machine guns, mines, and other types of weapons (up to and including satellite-based weapons and nuclear weapons). Players choose a vehicle, and an arena—or a series of arenas in the story mode—to engage in battle with opposing drivers. A variety of weapons and upgrades are obtainable by pick-ups scattered throughout the stage. The last driver alive is the winner. Although each individual game featur ...

Uno (dicycle)
The Uno is a novel self-balancing electric motorcycle using two wheels side by side (the configuration used by dicycles). The Uno III adds a third wheel that allows it to transform into a tricycle. Description The original Uno is controlled in forward motion by the rider shifting weight over the centre of gravity. When the rider shifts forward, the vehicle speeds up to regain balance, when the rider leans back, the vehicle slows. Steering is controlled by side-to-side motion of the rider. The vehicle senses this shift and raises one of the two wheels to allow the vehicle to tilt in the desired turn direction. The Uno III has two configurations, as a dicycle and as a tricycle. As a dicycle it operates much the same as the original Uno with forward and back motion of the rider affecting acceleration. The Uno III also utilizes a hand throttle to affect acceleration and braking. Instead of using rider side-to-side movement to control steering, the Uno III uses a rotating handleba ...

Electric Unicycle
An electric unicycle (often initialized as EUC or acronymized yuke or Uni) is a self-balancing personal transporter with a unicycle, 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, gyroscopes, and a magnetometer. In 2020, suspension models were introduced by three major manufacturers Begode, Kingsong and Inmotion. Operation Commercial units are self-balancing in a forward and backward direction, with side-to-side (lateral) stability being provided by the steering motions of the rider, similar to Bicycle and motorcycle dynamics. As of 2022, no commercial human-rideable unicycle has lateral self-balancing capabilities. However, a non-ridable, dual-axis self-balancing unicycle was demonstrated in 2012, with small, lightweight robots using a large weighted reaction wheel or control moment gyroscope. The control of a unicycle can be considered to be an inv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outline Of Cycling
:''This article is an outline about the activity of cycling. For an outline about bicycles themselves, see outline of bicycles.'' :The following ''outline'' is provided as an overview of, as well as a topical guide to cycling: Cycling, also called bicycling or biking, is the activity of using / riding bicycles, (at least partially) human-powered, wheeled vehicles (typically by foot pedalling), for purposes including transport, recreation, social interaction, exercise, sport, therapy, other purposes, or any combination thereof. Persons engaged in cycling are called cyclists, bikers, or sometimes bicyclists. They typically either dress for where they are going, or for the cycling, sometimes having another set of clothing with them, or arranged. Apart from regular two-wheeled bicycles, cycling also includes riding unicycles, tricycles, quadricycles, and other similar human-powered wheeled vehicles (HPVs). Some bicycles are sold with (electric) motors (e-bikes), or ot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onewheel
Onewheel is a self-balancing single wheel electric board-sport, recreational personal transporter, often described as an electric skateboard. Unlike the electric unicycle, the rider's feet (and body) are typically pointed at a perpendicular angle to the wheel and direction of travel. History The first device similar to a Onewheel was invented by Ben Smither in 2007. Future Motion Inc. founder and CEO Kyle Doerksen created a commercial version of the concept several years later. Doerksen holds two engineering degrees from Stanford University, including a master's degree in mechanical engineering. In 2013, he left his job at IDEO and started Future Motion Inc. in Santa Cruz. He launched Onewheel on Kickstarter on January 6, 2014; the Kickstarter exceeded its campaign goal of $100,000 and reached over $630,000 by January 27, 2014. The original Onewheel was released in 2015. It was followed by the Onewheel+ in 2017, the Onewheel+ XR in 2018, and the Onewheel Pint in 2019. Future ...

Monowheel Tractor
A monowheel tractor or monowheel-drive tractor is a light transport and agricultural vehicle that is driven and controlled by an engine and steering mechanism mounted on a single large wheel, with the load-carrying body trailing behind. Despite the name, they are tricycles. Development Monowheel tractors developed in two periods, both during times of rapid upheaval after warfare. Both types had quite different circumstances and goals. Small wheel tractors appeared after World War I, during a time of new opportunity. Large-wheel tractors appeared after World War II, during a period of austerity. Small wheel tractors The first monowheel tractors appeared in the 1920s, as a result of technical developments in small petrol engines. These had been driven by improving engine technology, particularly for motorbikes. Such engines now represented an affordable and portable power source. An entire powertrain could be constructed as a single monobloc unit, carried on a single wheel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kugelpanzer
The ''Kugelpanzer'' ("ball tank") is a one-man armoured vehicle built by Nazi Germany during World War II. The history of the vehicle is practically unknown other than the fact that at least one example was exported to the Empire of Japan and used by the Kwantung Army. The machine remains something of a mystery due to the lack of records and the incompleteness of the sole surviving model. Surviving example Only one example of the ''Kugelpanzer'' still exists today. It was captured by the Red Army in Manchuria and is on display in the collection of German armoured vehicles at the Kubinka Tank Museum in Moscow where it is described simply as "exhibit no. 37". There is no record of it ever having been used in combat. However, another report states that it was captured at the Kummersdorf proving grounds along with the infamous ''Maus'' super-heavy tank. The vehicle was modified after its capture, repainted and its drive removed. In 2000 the original paintwork was restored. Theo ...

Centreless Wheel
A centreless wheel is a wheel that lacks a centre or hub, instead being supported and driven at the rim. Design Centreless wheels are toroidal in shape and have one or multiple bearings along the rim. Propulsion can be achieved in different ways, such as with gear teeth along the inner surface of the rim. They can be made lighter than solid and spoked wheels, resulting in better handling and less rotational inertia. The lack of spokes or a traditional hub also allows for more space, which can be used to more easily package a hub motor. While Franco Sbarro was the first to replace vehicles' conventional wheels with hubless wheels in 1989, monowheels, which are similar in practice, predate Sbarro's hubless-wheel vehicles by more than 100 years. The research and development of centreless wheels has not been pursued by any large company due to their complexity, with their use limited to small companies and scientific analyses.

Cyr Wheel
The Cyr wheel (also known as the roue Cyr, mono wheel, or simple wheel) is an acrobatic apparatus that consists of a single large ring made of aluminum or steel with a diameter approximately taller than the performer. The performer stands inside the Cyr wheel and grasps its rim, causing it to roll and spin gyroscopically while performing acrobatic moves in and around the rotating wheel. The apparatus and its movement vocabulary have some similarities with the German wheel, but while the German wheel consists of two large rings linked together by horizontal crossbars and has handles for the performer to hold onto, the modern Cyr wheel consists of a single ring and has no handles. The Cyr wheel takes its name from Daniel Cyr, who revived its popularity, utilising it as a circus apparatus at the end of the 20th century. Cyr wheel requires a solid, non-slippery surface such as a dance floor, concrete or stage and a relatively large performance area. Origin There are records of pe ...
