Countersteer
Countersteering is used by single-track vehicle operators, such as cyclists and motorcyclists, to initiate a turn toward a given direction by momentarily steering counter to the desired direction ("steer left to turn right"). To negotiate a turn successfully, the combined center of mass of the rider and the single-track vehicle must first be leaned in the direction of the turn, and steering briefly in the opposite direction causes that lean. The rider's action of countersteering is sometimes referred to as "giving a steering command". The scientific literature does not provide a clear and comprehensive definition of countersteering. In fact, "a proper distinction between steer torque and steer angle ... is not always made." How it works When countersteering to turn right, the following is performed: * A torque on the handlebars to the left is applied. * The front wheel will then rotate about the steering axis to the left and the tire will generate forces in the contact patch t ...

Tilting Three-wheeler
A tilting three-wheeler, tilting trike, leaning trike, or even just tilter, is a three-wheeled vehicle and usually a narrow-track vehicle whose body and or wheels tilt in the direction of a turn. Such vehicles can corner without rolling over despite having a narrow axle track because they can balance some or all of the roll moment caused by centripetal acceleration with an opposite roll moment caused by gravity, as bicycles and motorcycles do. This also reduces the lateral acceleration experienced by the rider, which some find more comfortable than the alternative. The narrow profile can result in reduced aerodynamic drag and increased fuel efficiency. These types of vehicles have also been described as "man-wide vehicles" (MWV). As with tricycles that do not tilt, there are a variety of feasible choices of how the wheels are arranged, which wheels are steered, and which wheels are driven. In addition, there are a variety of feasible choices for which wheels tilt and whic ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Motorcycle Safety
Motorcycle safety is the study of the risks and dangers of motorcycling, and the approaches to mitigate that risk, focusing on motorcycle design, road design and traffic rules, rider training, and the cultural attitudes of motorcyclists and other road users. Riding motorcycles on public roads carries several times the risk of riding in cars, which themselves are more risky than public conveyances like buses and trains. The human factors of motorcycle crashes are roughly equal between rider behavior and the actions of drivers sharing the roads. Technological changes, especially in the latter half of the 20th century, have made significant improvements in motorcycle safety. Serious research into motorcycle safety began in the US with the Hurt Report in 1981, followed by major studies in Europe and others. The main result of this research has been a greater emphasis on rider training and stricter licensing requirements. The US military recognized the need for their own focused motorcyc ...

Single-track Vehicle
A single-track vehicle is a vehicle that leaves a single ground track as it moves forward. Single-track vehicles usually have little or no lateral stability when stationary but develop it when moving forward or controlled. In the case of wheeled vehicles, the front and rear wheel usually follow slightly different paths when turning or when out of alignment. Single-track vehicles have unique dynamics that, in the case of wheeled vehicles, are discussed at length in bicycle and motorcycle dynamics, that usually require leaning into a turn, and that usually include countersteering. Single-track vehicles can roll on wheels, slide, float, or hydroplane.

Bicycle
A bicycle, also called a pedal cycle, bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe. By the early 21st century, more than 1 billion were in existence. These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved, especially since the advent of modern ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Canada Safety Council
The Canada Safety Council is a national, non-profit, charitable organization dedicated to safety. It works to prevent deaths and injuries by promoting education and awareness across Canada. It provides marketing opportunities for its sponsors. During the COVID-19 pandemic, CSC received a $220,000 grant from the Public Health Agency of Canada The Public Health Agency of Canada (PHAC; french: Agence de la santé publique du Canada, ASPC) is an agency of the Government of Canada that is responsible for public health, emergency preparedness and response, and infectious and chronic dis ...'s Immunization Partnership Fund for a project titled the “Elmer Vaccine Education and Awareness Program”.

Carver (automobile)
Carver Europe B.V. is a Dutch company that develops and manufactures three-wheeled electric enclosed man-wide vehicles. The company's core technology is the Dynamic Vehicle Control (DVC) system, which enables narrow vehicles to make banked turns, aiding stability when turning at higher speeds. Its headquarters, assembly factory, experience center, and sales and marketing activities, are in Leeuwarden. The engineering team is located in 's-Gravendeel and operates under the name Carver Technology B.V. The company was founded in 1994 by Chris van den Brink and Harry Kroonen as Brink Technologies Group B.V., although its history can be traced further back to 1990. Since then, the company has seen several changes to its name and structure. The current CEO is Anton Rosier and Chris van den Brink operates as CTO (Chief Technology Officer).

Motorcycling
Motorcycling is the act of riding a motorcycle. For some people, motorcycling may be the only affordable form of individual motorized transportation, and small-displacement motorcycles are the most common motor vehicle in the most populous countries, including India, China and Indonesia. In developing countries, motorcycles are overwhelmingly utilitarian due to lower prices and greater fuel economy. Of all motorcycles, 58% are in the Asia Pacific and Southern and Eastern Asia regions, excluding car-centric Japan. Motorcycles are mainly a luxury good in developed nations, where they are used mostly for recreation, as a lifestyle accessory or a symbol of personal identity. Beyond being a mode of motor transportation or sport, motorcycling has become a subculture and lifestyle. Although mainly a solo activity, motorcycling can be social and motorcyclists tend to have a sense of community with each other. Reasons for riding a motorcycle For most riders, a motorcycle is a che ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Piaggio MP3
The Piaggio MP3 (''Moto Piaggio a 3 ruote'', "Piaggio moto with 3 wheels") is a tilting three-wheeled scooter by Italian manufacturer Piaggio. First marketed in 2006, it is noted for its combination of two front wheels and a single rear wheel. Suspension mechanism Utilising its three-wheel mechanism developed by Piaggio together Marabese Design, the MP3 can be stopped and parked, without using a traditional kickstand or centre stand, and can be parked on irregular or side-sloping ground. The front suspension is similar to the single-sided trailing arm of Vespa-style suspensions, linked by an alloy parallelogram and a central steering arm. When moving at slow speeds or stopped, the rider maintains balance by maintaining forward motion or placing feet on the ground. The front suspension locks or unlocks using a switch, which is located just below the throttle on the right handlebar. The suspension lock can only be activated manually, at low speeds or at a stop; the lock is au ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
