Electric bicycle laws
Many countries have enacted electric bicycle laws to regulate the use of electric bicycles. Countries such as the United States and Canada have federal regulations governing the safety requirements and standards of manufacture. Other countries like the signatories of the European Union have agreed to wider-ranging legislation covering use and safety of their term EPAC (electric pedal-assisted cycles). However, confusion remains regarding the various laws involving electric bicycles. This stems from the fact that while some countries have national regulations, the legality of road use is left to states and provinces, and then complicated further by municipal laws and restrictions.
Three-wheeler
A three-wheeler is a vehicle with three wheels. Some are motorized tricycles, which may be legally classed as motorcycles, while others are tricycles without a motor, some of which are human powered vehicles and animal powered vehicles. Many three-wheelers which exist in the form of motorcycle-based machines are often called trikes and often have the front single wheel and mechanics similar to that of a motorcycle and the rear axle similar to that of a car. Often such vehicles are owner-constructed using a portion of a rear-engine, rear-drive Volkswagen Beetle in combination with a motorcycle front end.
Bicycle and motorcycle dynamics
Bicycle and motorcycle dynamics is the science of the motion of bicycles and motorcycles and their components, due to the forces acting on them. Dynamics falls under a branch of physics known as classical mechanics. Bike motions of interest include balancing, steering, braking, accelerating, suspension activation, and vibration. The study of these motions began in the late 19th century and continues today. Bicycles and motorcycles are both single-track vehicles and so their motions have many fundamental attributes in common and are fundamentally different from and more difficult to study than other wheeled vehicles such as dicycles, tricycles, and quadracycles.
Countersteering
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.
All-terrain vehicle
An all-terrain vehicle (ATV), also known as a quad, quad bike, three-wheeler, four-wheeler or quadricycle as defined by the American National Standards Institute (ANSI) is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger.
Wheelchair
A wheelchair, often abbreviated to just "chair", is a chair with wheels, used when walking is difficult or impossible due to illness, injury, or disability. Wheelchairs come in a wide variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The most widely recognised distinction is between powered wheelchairs ("powerchairs"), where propulsion is provided by batteries and electric motors, and manually propelled wheelchairs, where the propulsive force is provided either by the wheelchair user/occupant pushing the wheelchair by hand ("self-propelled"), or by an attendant pushing from the rear ("attendant propelled").
Electric motorcycles and scooters
Electric motorcycles and scooters are plug-in electric vehicles with two or three wheels powered by electricity. The electricity is stored on board in a rechargeable battery, which drives one or more electric motors. Electric scooters (as distinct from motorcycles) have a step-through frame. The early history of electric motorcycles is somewhat unclear. On 19 September 1895, a patent application for an "electrical bicycle" was filed by Ogden Bolton Jr. of Canton Ohio. On 8 November of the same year, another patent application for an "electric bicycle" was filed by Hosea W. Libbey of Boston. At the Stanley Cycle Show in 1896 in London, England, bicycle manufacturer Humber exhibited an electric tandem bicycle.

Bradbury Motor Cycles
Bradbury Motor Cycles was a British motorcycle manufacturer based in Oldham, England and established in 1902. Originally involved in the manufacture of machine tools, sewing machines and cycles, their first motorcycles were bicycles with clip-on Minerva engines. The Bradbury factory went on to develop and produce a range of single-cylinder motorcycle, V-twins and horizontally opposed twins. The 1912 Bradbury motorcycles were one of the earliest with variable gearing. Although the factory survived the First World War it closed in 1924. The company was established in 1852 as Bradbury & Co., and was Britain's and Europe's first sewing machine manufacturer.
C J Edwards Chambers
C J Edwards Chambers is a heritage-listed riparian office building at 174 Quay Street, Rockhampton, Rockhampton Region, Queensland, Australia. It was designed by Edwin Morton Hockings and built in 1914. It is also known as River Motors Pty Ltd, Rockhampton Motors Garage and Engineers, and Sydney V Golik and Co Motor and Car Truck Dealers. It was added to the Queensland Heritage Register on 21 October 1992. Edwards Chambers was constructed in 1914 as a motor garage for the Howard Motor & Cycle company of Rockhampton. It is representative of an early motor garage in a provincial city. The Archer brothers had made a private expedition to the Rockhampton district in 1853, and were the first Europeans to record and chart the Fitzroy River.

Freestyle skateboarding tricks
A freestyle skateboarding trick is a trick done on a skateboard while freestyle skateboarding. Some of these tricks are done in a stationary position, unlike many other skateboarding tricks. The keys to a good freestyle contest run are variety, difficulty, fluidity, and creativity. It should also be noted that this is a partial list, and a full list would never be possible, because new tricks and new combinations are always being created. Notes:   1970s skate competitions such as the ones shown in Lords of Dogtown would often have an event to see who could do the most consecutive 360 spins on a skateboard.
The Motor Cycle
The Motor Cycle was one of the first British magazines about motorcycles. Launched by Iliffe and Sons Ltd in 1903, its blue cover led to it being called "The Blue 'un" to help distinguish it from its rival publication "Motor Cycling", which, using a green background colour, was known as "The Green 'un". Many issues carried the strapline "Circulated throughout the World". The covers eventually used a variety of different background colours after 1962, with a name-change to "Motor Cycle". Noted for detailed road tests of contemporary motorcycles and articles on readers' bikes, the magazine had regular features, including "Current Chat" and "Letters to the Editor" where many of the key issues relating to British motorcycling of the day were debated.

That's really cool! What makes them different apart from having an extra wheel?
0_Wizard
They are better for long distance travel due to comfort while two wheel version is better for just cruising. 
Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sport including racing, and off-road riding.

Economy car
An economy car is an automobile that is designed for low-cost purchase and operation. Typical economy cars are small (compact or subcompact), lightweight, and inexpensive to buy. Economy car designers are forced by stringent design constraints to be inventive. Many innovations in automobile design were originally developed for economy cars, such as the Ford Model T and the Austin Mini. Gordon Murray, the Formula 1 and Mclaren F1 designer, said when designing his new Murray T.25 city car: "I would say that building a car to sell for six thousand pounds and designing that for a high-volume production, where you have all the quality issues under control, is a hundred times more difficult than designing a Mclaren F1, or even a racing car.
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both roadholding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear.
Four-wheel drive
Four-wheel drive, also called 4×4 ("four by four") or 4WD, refers a two-axled vehicle with a drivetrain capable of providing torque to all its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive-shaft and, in many instances, additional gear ranges. A four-wheeled vehicle with torque supplied to both axles is described as "all-wheel drive" (AWD). However, "four-wheel drive" typically refers to a set of specific components and functions, and/or intended offroad application, which generally complies with modern use of the terminology.
Tesla Model S
The Tesla Model S is a full-sized all-electric five-door, luxury liftback, produced by Tesla, Inc., and introduced on June 22, 2012. It scored a perfect 5.0 NHTSA automobile safety rating. The EPA official range for the 2017 Model S 100D, which is equipped with a battery pack, is , higher than any other electric car. The EPA rated the 2017 90D Model S's energy consumption at 200.9 watt-hours per kilometer (32.33 kWh/100 mi or 20.09 kWh/100 km) for a combined fuel economy of 104 miles per gallon gasoline equivalent ( or ). In 2016, Tesla updated the design of the Model S to closely match that of the Model X. , the following versions are available: 75D, 100D and P100D.
Citroën XM
The Citroën XM is an executive car that was produced by the French automaker Citroën between 1989 and 2000. Citroën sold 333,775 XMs during the model's 11 years of production. The XM was voted 1990 European Car of the Year. Launched on 23 May 1989, the XM was the modern iteration of the "Big Citroën", a flagship saloon replacement for the Citroën CX. It went on sale in its native France immediately afterwards, and was available in right-hand drive on the UK market from October 1989. The XM estate was launched in the spring of 1991, until which time the estate version of the CX remained in production.
Independent Transport Commission
The Independent Transport Commission, abbreviated to ITC, is a research charity and think tank based in the United Kingdom, devoted to exploring issues in the fields of transport, planning and land use. It is politically neutral, and has established a reputation as a nationally respected independent voice on transport and planning policy. It played a key role shaping policy in the 2000s (decade) with the publication of a series of authoritative and groundbreaking reports on road pricing, suburban planning, long distance travel, and the future of transport. The ITC increased its influence to policymakers since 2010 with a series of reports on UK aviation, freight and logistics, paying for roads, and the spatial effects of High-Speed Rail.
Trade route
A trade route is a logistical network identified as a series of pathways and stoppages used for the commercial transport of cargo. The term can also be used to refer to trade over bodies of water. Allowing goods to reach distant markets, a single trade route contains long distance arteries, which may further be connected to smaller networks of commercial and noncommercial transportation routes. Among notable trade routes was the Amber Road, which served as a dependable network for long-distance trade. Maritime trade along the Spice Route became prominent during the Middle Ages, when nations resorted to military means for control of this influential route.

That's true. Is the suspension any different on them?
0_Wizard
Not really. The big factor that makes them apart is that two wheeled motor cycles fatalities per mile traveled was 37 times higher for  than for cars. Three wheeled motor cycles was much less.
According to the United States Department of Transportation the number of fatalities per vehicle mile traveled was 37 times higher for motorcycles than for cars.

Motorcycle
A motorcycle often called a bike, motorbike, or cycle is a two- or three-wheeled motor vehicle. Motorcycle design varies greatly to suit a range of different purposes: long distance travel, commuting, cruising, sport including racing, and off-road riding. Motorcycling is riding a motorcycle and related social activity such as joining a motorcycle club and attending motorcycle rallies. In 1894, Hildebrand & Wolfmüller became the first series production motorcycle, and the first to be called a motorcycle. In 2014, the three top motorcycle producers globally by volume were Honda, Yamaha (both from Japan), and Hero MotoCorp (India).

Transportation safety in the United States
Transportation safety in the United States encompasses safety of transportation in the United States, including automobile accidents, airplane crashes, railroad and motorcoach fatalities and maimings, and other mass transit incidents, although the most fatalities are generated by road accidents. The U.S. government's National Center for Health Statistics reported 33,736 motor vehicle traffic deaths in 2014. This exceeded the number of firearm deaths, which was 33,599 in 2014. According to another U.S. government office, the National Highway Traffic Safety Administration, motor vehicle crashes on U.S. roadways claimed 32,744 lives in 2014 and 35,092 in 2015.

Plug-in electric vehicles in the United States
The adoption of plug-in electric vehicles in the United States is actively supported by the American federal government, and several state and local governments. , cumulative sales in the U.S. totaled 764,666 highway legal plug-in electric vehicles since the market launch of the Tesla Roadster in 2008, , the American stock represented 28.1% of the global light-duty plug-in stock, and the U.S. had the world's third largest stock of plug-in passenger cars after China and Europe. The U.S. market share of plug-in electric passenger cars increased from 0.14% in 2011 to 0.62% in 2013. The plug-in segment reached a market share of 0.75% in 2014 and fell to 0.66% in 2015.
Plug-in electric vehicle
A plug-in electric vehicle (PEV) is any motor vehicle that can be recharged from an external source of electricity, such as wall sockets, and the electricity stored in the rechargeable battery packs drives or contributes to drive the wheels. PEV is a subset of electric vehicles that includes all-electric or battery electric vehicles (BEVs), plug-in hybrid vehicles (PHEVs), and electric vehicle conversions of hybrid electric vehicles and conventional internal combustion engine vehicles. In China, plug-in electric vehicles are called new energy vehicles (NEVs). Plug-in cars have several benefits compared to conventional internal combustion engine vehicles.
Motorcycle safety
Motorcycle safety concerns many aspects of vehicle and equipment design as well as operator skill and training that are unique to motorcycle riding. According to the U.S. National Highway Traffic Safety Administration (NHTSA), in 2006, 13.10 cars out of 100,000 ended up in fatal crashes. The rate for motorcycles is 72.34 per 100,000 registered motorcycles. Motorcycles also have a higher fatality rate per unit of distance travelled when compared with automobiles. Per vehicle mile traveled, motorcyclists' risk of a fatal crash is 35 times greater than a passenger car. In 2004, figures from the UK Department for Transport indicated that motorcycles have 16 times the rate of serious injuries compared to cars.
