The '''Segway PT''' (formerly HT) is a two-wheeled, self-balancing ] device invented by ] and unveiled in December ]. It is available in various models and form factors produced by the company Segway Inc. of ]. The name "Segway PT" stands for "Segway Personal Transporter", while the older acronym, HT, stood for "Human Transporter". A '''Segway''' is a ], self-balancing ] device invented by ]. The name is a registered trademark of ]. 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."


Ninebot, a ]-based transportation robotics startup rival, acquired Segway Inc. in April 2015, broadening the company to include other transportation devices. In June 2020, it was announced that it would no longer make the Segway PT.<ref name=":0">{{Cite web|last=Wilson|first=Mark|date=2020-06-23|title=Segway, the most hyped invention since the Macintosh, ends production|url=https://www.fastcompany.com/90517971/exclusive-segway-the-most-hyped-invention-since-the-macintosh-to-end-production|access-date=2020-06-24|website=Fast Company|language=en-US}}</ref><ref name=":1">{{Cite web|date=2020-06-23|title=Segways scrapped after two decades of high-profile falls|url=https://www.abc.net.au/news/2020-06-24/segway-ends-production-of-vehicle-falls/12386530|access-date=2020-06-24|website=www.abc.net.au|language=en-AU}}</ref>
]s and motors in the base keep the Segway upright at all times. Users lean forward to go forward, and back to move backwards. In new models turning is also done by leaning left and right while in older/discontinued models via twisting a hand grip on the left handlebar. Segway PTs are driven by electric motors at up to 5.6 ] (12.5 ]/20 ]) (4.5 m/s in the small discontinued p-Series), about the speed an average person can run. ]s are used to detect departures from perfect balance. In laws that regulate it, the applicable category is sometimes called "electric personal assistive mobility device" (EPAMD).


==History==
The Segway is designed to replace larger forms of transportations like cars, vans, SUVs etc, much like other scooters or motorcycles do, yet be even lower impact (much cleaner, quieter, smaller and safer). Kamen's Vision: The EPA states that 500 million car trips per day in the US are less than 5 miles and contain only one person in the vehicle. If only a percentage of those used a tiny electric "car" instead, the positive effects could be considerable.

]]
In ], Segway discontinued all previous models and announced new second generation designs that upgraded many elements of the previous transporters. New materials, new industrial designs and new functionalities that affected nearly every part of the Personal Transporter were revealed. The new Gen II PT, marketed under the two product lines, i2 and x2, has a distinct new capability to allow users to steer by leaning to the right or left, which matched the intuitive nature of moving forward and backward. Other features were also announced, including numerous tech functions available on the machine as well as by wireless InfoKey access. The changes are substantial and allow the transportation device to become even more intuitive and a greater natural extension of the rider. The industrial design changes appear to appeal more to the motorcycle enthusiast with brushed aluminum and smoothed solder points on metal. The pricing structure remains the same for the most part. Much like the PC during its first 20 years, the PT appears to have a price point that sales and profits meet in an equilibrium that the manufacturers are happy with.


Segway Inc. was acquired by British businessman ] from its U.S. inventor ] in December 2009. A year later, Heselden died after he "plunged into the ] while riding a rugged country version" of Segway PT.<ref>{{cite news |url=https://www.nbcnews.com/id/wbna39377851 |title=Segway company owner rides scooter off cliff, dies |quote=A British businessman, who bought the Segway company less than a year ago, died after riding one of the scooters off a cliff and into a river near his Yorkshire estate. |publisher=] |accessdate=February 3, 2022}}</ref><ref>{{cite news|url=https://www.bbc.com/news/uk-england-leeds-11465512|title=Inquest into Segway head's death|work=BBC News|date=4 October 2010|publisher=}}</ref>
Although the company has faced disappointments, its sales have increased 50% year-over-year since its consumer sales began in March 2003 and totalled 23,500 by mid 2006 (when revealed by a voluntary recall for a software patch). Segway Inc is reported to be focused on expanding their presence in industry as well as consumer markets with the new models. The device's relatively high price for a scooter/small motorcycle (new units for sale between US$4000 and US$5500, depending upon the model) is believed to be the main factor responsible for consumer demand being lower than expected, yet also the reason the company is still making a profit. Segway Inc. has established independent dealerships (not franchises) throughout the ]s where people can examine and test-drive the Segway PTs. Segway Inc. has signed distribution agreements in several foreign markets, including ] and ]. The company currently has more than 100 dealers and distributors internationally.

In March 2014, Segway Inc. announced third generation designs, including the i2 SE and x2 SE sport, new LeanSteer frame and powerbase designs, with integrated lighting.<ref name=SELaunch>{{cite press release| url=https://www.prnewswire.com/news-releases/segway-launches-new-se-personal-transporters-pts-and-segsolution-accessory-packages-251918501.html|title=Segway Launches New SE Personal Transporters (PTs) And SegSolution Accessory Packages|publisher=Segway|date=24 March 2014|access-date=2 January 2020}}</ref>
Though its creators believe the new Segway PT is ideal for dense urban areas, some Americans believe that US cities (such as ], ], or ]) were designed to be navigated primarily by automobiles alone through use of ]s and the ] system and that there is little room for alternative forms of transportation. Communities in which the Segway PT would be most successful would be those that are pedestrian-friendly, that is, in walkable communities. In professional planning, "smart growth" encourages communities with shorter distances between home, work, stores, and recreational areas. Therefore, the success of the Segway PT in the market of personal transportation (as opposed to as a recreational device) depends largely on both urban development trends toward "smart growth" rather than toward "]," as well as the availability of future more affordable Segway models. Its acceptance may also depend on something less complex: the price of gasoline in the United States. If the price of gas passes $4/gallon, alternative forms of transportation may quickly gain respect (as they have for years in Europe).].]]


===Subsidiary of Ninebot===
If the distance to travel is short, a Segway PT can be used for personal transportation between home and office, for getting around the city center, shopping, outdoor trips, etc. It is already used in some ]s by both visitors and employees. Numerous companies organize guided group tours on Segway HTs in the USA, France, Thailand and other countries. Several organizations have run pilot tests on Segway business use, among them police departments, post offices, warehouses, and utility companies. Some of these pilot programs have demonstrated that Segway PTs can often significantly reduce cost and quickly repay the investment; however, the massive fleet sales which Kamen and others predicted have not yet been forthcoming. New second-generation models and new lithium ion batteries that double range may alter this dynamic. Change is hard, for example, during a trial by ] to deliver mail on foot, some mail carriers noted that they could not sort mail or hold an umbrella while operating a Segway PT and thus would rather drive large trucks.

] ] patrolling on a Segway.]]The Segway PT was developed after the ] ] and was intended to be used primarily by able-bodied users. Still, an increasing number of disabled people (4000-7000, according to a group called ) use Segways to enhance their limited mobility. Among these users are people with ] or ], ] and even ]s in particular a growing group of war veterans. Using a Segway PT instead of a traditional wheelchair or an expensive iBOT (that costs four to five times as much as a Segway PT) allows them to easily travel around the city, while easing social interactions. This has also been supported by a product called the that adds a seat to the Segway PT for users with limited capacity to stand for long periods. However, Segways cannot be marketed as medical devices, because Segways have not been approved by the ] as a medical device and because ] has exclusive rights to the medical uses of the balancing technology found within the ] and Segway PT.


===End of production===
Most of the Segway PT technology is concentrated in its base with the handle being only useful for the ] rider. Stripped of the handle, the Segway PT becomes a universal ]ic platform that is still capable of balancing whatever is installed and of moving around as easily as with a human. The Segway robotic platform is widely used by robotics developers in universities and private companies.
Only 140,000 units were sold during the lifetime of the product, and in the later years the Segway PT only made up 1.5% of total company profit.<ref name=":0" /> Factors contributing to the end of production include the price (US$5,000 at launch), and the learning curve in learning to balance on a Segway PT which has led to notable accidents involving ], ], ], ], and Segway Inc. previous owner ].<ref name=":1" /> While the Segway has remained popular for security and tourism, ] have been more popular for personal mobility.<ref name=":0" /><ref name=":1" />


== Technology == === UTVs ===
In February 2022, Segway entered the UTV (]) market.{{Citation needed|reason=No current reference|date=April 2024}}
The Segway PT has ]s powered by ] which can be charged from household current. It balances with the help of dual ]s with proprietary software, two tilt sensors, and five ]s. (The gyroscopes do not affect the balance; they are merely used as sensors, see detail below.) The servo motors rotate the wheels forwards or backwards as needed for balance or propulsion. The rider accelerates or decelerates by leaning forward or backwards in the direction he or she wishes to travel. On older models, steering is controlled by a twist grip on the left handlebar, which simply varies the speeds between the two motors, rotating the Segway PT (a decrease in the speed of the left wheel would turn the Segway PT to the left). Newer models enable the use of "leaning" to steer as well as move forwards or backwards.


==Products==
The Segway PT is built simply to stay balanced in one place. Designed to mirror the process of human walking, if the rider standing on an initially balanced Segway PT leans forward, therefore offsetting the balance, the PT moves forward to regain balance just as in walking a leg moves forward to retain balance. With the Segway PT, changes from a balanced status are first detected by the gyroscopes, and signals are passed on to the onboard computers which then direct motors to regain balance. This process occurs about 100 times per second, so small adjustments to maintain balance occur almost immediately after the balance is offset by the rider.
At the end of production in 2020, Segway Inc. was selling these five self-balancing scooters:


;Professional
The side effect of this balancing system is that as the Segway PT balances itself the entire unit changes position in the direction it has moved to restore balance. (For example, if the rider leans forward, the entire Segway PT will move forward from its original position, until the rider restores an upright position on the unit.) This is precisely how the Segway PT is controlled -- the balancing and movement is essentially one combined system. Designed much like the physiology of human walking, the Segway system is a balancing system that leads to intuitive motion.

;Consumer
Riders who have had experience with the Segway PT have undoubtedly felt its ] (speed limiting) mechanism. When the Segway PT approaches the maximum speed allowed by the software, it intentionally begins to tilt slightly backwards. This moves the platform out in front, and leans the handlebars backwards towards the rider, eventually nudging the rider to lean back slightly and slow the Segway PT down. If not for the governor, riders would be able to lean farther than the motor could even compensate for, like running faster than your legs can keep up with. The Segway PT also slows or stops immediately if the handlebar of the unit (or forward bag) nudges into any obstacle in front of it.

== Operation ==
Although bicycles and traditional scooters must be "at speed" to balance, the Segway PT can balance while standing still. Yet, a Segway PT must be turned on before it is usable. While it is off, the Segway PT is unable to balance, and the kickstand will not hold a person's weight. The original Segway models were activated using one of three keys:

*Black Key &mdash; for beginners. Slowest speed (electronically limited to no more than 6 mph); slower turning rate.
*Yellow Key &mdash; for intermediate users and/or sidewalks. Faster speed-up to 8 mph; faster turning rate.
*Red Key &mdash; for more advanced users in open areas. Maximum speed-up to 10 mph on p-Series and 12.5mph on i-Series; and max turning rate.

For the new i2 and x2, you use an InfoKey instead to control settings. The Infokey can turn on the PT from up to 15 feet away, as well as turn on beginner mode (the equivalent of the old Black Key) or advanced mode (the equivalent of the Red Key), show mileage and a trip odometer, as well as put the Segway into Security mode, which locks the wheels and will set off an alarm if moved, to prevent theft.

Once it is turned on, the original Segways enter a "Power-Assist" mode (for help pulling it up steps and ramps) and the new Gen II models enter a "Riderless Balance" mode. In the older models in Power-Assist mode twisting the left handlebar grip like a motorcycle throttle moves it forward and backward. In power-assist mode it is still not balancing and is not safe to ride. Once powered on and in Power-Assist mode, "Balance mode" is entered by holding the Segway level and pressing down its mode button (red or blue in newer models). In Balance mode, the rider mounts and rides. While riding, there is no traditional throttle. Leaning forward accelerates; leaning back decelerates and goes in reverse. Twisting the left handlebar grip now turns the HT to the right or left.

The dashboard indicator window on the handlebar indicates battery charge level by a ring of black bars around a green smiling face icon. The face smiles and is backlit in green during standard operation. If the battery runs too low or a subsystem is not functioning well, the Segway face will frown and backlight turn red. If it's unsure of the rider's safety it will perform a "safety shutdown" and will vibrate and beep for seven seconds (to warn the rider to dismount) before shutting off.

The Segway is turned off by stepping off the platform and then pressing and holding the red or blue-colored mode button until shutdown tones and the face icon's sleeping appearance indicate the shutdown process is engaged. When complete (takes 3 seconds to shutdown all CPUs and subsystems) the Segway and its display turns off.

== Recalls ==
In September of 2003 the Segway HT was recalled to patch its software to version 12.0, which negated the risk that a rider may completely drain the battery.

In September of 2006, all 23,500 of the vehicles were voluntarily recalled. A bug in the software was revealed that in a very rare sequence of events (including the rider jumping in the air at full speed) could cause the segway to get confused and try to stop. Segway released a patch to its software (version 14.2) to resolve the problem.

A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. The name 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."

Ninebot, a Beijing-based transportation robotics startup rival, acquired Segway Inc. in April 2015, broadening the company to include other transportation devices. In June 2020, it was announced that it would no longer make the Segway PT.

History

Independent company

The Segway PT, referred to during development and initial marketing as the Segway HT, was developed from the self-balancing iBOT wheelchair which was initially developed at University of Plymouth, in conjunction with BAE Systems and Sumitomo Precision Products. The first patent of human transporter was filed in 1994 and granted in 1997, followed by others, including one submitted in June 1999 and granted in October 2001.

Prior to its introduction, a news report about a proposal for a book about the invention, development, and financing of the Segway PT led to speculation about the device and its importance. John Doerr speculated that it would be more important than the Internet. South Park devoted an episode to making fun of the hype before the product was released. Steve Jobs was quoted as saying that it was "as big a deal as the PC", (he later expressed a negative opinion, saying that it "sucked", presumably referring to "the design" – but also referred to the (presumably high) price point, asking, "You're sure your market is upscale consumers for transportation?") The device was unveiled on 3 December 2001, following months of public speculation, in Bryant Park, New York City, on the ABC News morning program Good Morning America, with the first units delivered to customers in early 2002.

The original Segway PT models featured three speed settings: 6 miles per hour (9.7 km/h), 8 miles per hour (13 km/h) with faster turning, and 10 miles per hour (16 km/h). Steering of early versions was controlled using a twist grip that varied the speeds of the two motors. The range of the p-Series was 6–10 miles (9.7–16.1 km) on a fully charged nickel metal hydride (NiMH) battery with a recharge time of four to six hours. In September 2003, the Segway PT was recalled, because if users ignored repeated low-battery warnings on the PTs, it could ultimately lead them to fall.

In August 2006, Segway Inc. discontinued all previous models and introduced the i2 and x2 products, which were steered by leaning the handlebars to the right or left, had a maximum speed of 12.5 mph (20.1 km/h) from a pair of two-horsepower (1.5 kW) Brushless DC electric motors with regenerative braking and a range of up to 15–25 mi (24–40 km), depending on terrain, riding style, and state of the batteries. Recharging took eight to ten hours. The i2 and x2 also introduced the wireless InfoKey which could show mileage and a trip odometer, and put the vehicle into security mode, which locked the wheels and set off an alarm if it was moved, and could also be used to turn on the PT from up to 15 feet (4.6 m) away.

Segway Inc. was acquired by British businessman Jimi Heselden from its U.S. inventor Dean Kamen in December 2009. A year later, Heselden died after he "plunged into the River Wharfe while riding a rugged country version" of Segway PT.

Versions of the product prior to 2011 included (in order of release):

  • Segway i167 (2001 revealed, 2002 shipped)
  • Segway e167: As i167, with addition of electric kickstand
  • Segway p133: Smaller platform and wheels and less powerful motors than the i and e Series with top speed of 10 miles per hour (16 km/h) in the p-Series
  • Segway i180: With lithium-ion batteries
  • Segway XT: The first Segway designed specifically for recreation
  • Segway i2 (2006): The first on-road Segway PT with LeanSteer
  • Segway x2 (2006): The first off-road Segway PT with LeanSteer

In March 2014, Segway Inc. announced third generation designs, including the i2 SE and x2 SE sport, new LeanSteer frame and powerbase designs, with integrated lighting.

Subsidiary of Ninebot

Ninebot, a Beijing-based transportation robotics startup and a rival of Segway Inc., acquired Segway Inc. in April 2015, having raised $80M from Xiaomi and Sequoia Capital. The acquisition came months after the U.S. International Trade Commission agreed to investigate Segway Inc.'s claim that Ninebot and other companies were infringing on its patents and copyrights. Segway Inc. requested the blocking of imports of competing scooters into the United States.

In June 2016, Segway Inc. launched the Segway miniPRO, a smaller self-balancing scooter.

End of production

Only 140,000 units were sold during the lifetime of the product, and in the later years the Segway PT only made up 1.5% of total company profit. Factors contributing to the end of production include the price (US$5,000 at launch), and the learning curve in learning to balance on a Segway PT which has led to notable accidents involving Usain Bolt, George W. Bush, Ellen DeGeneres, Ian Healy, and Segway Inc. previous owner Jimi Heselden. While the Segway has remained popular for security and tourism, electric scooters have been more popular for personal mobility.

UTVs

In February 2022, Segway entered the UTV (Utility Terrain Vehicle) market.

Products

At the end of production in 2020, Segway Inc. was selling these five self-balancing scooters:

Professional
  • Segway i2 SE (professional self-balancing scooter for use in warehouses and other locations)
  • Segway x2 SE (ruggedised self-balancing scooter for use on most challenging terrain)
  • Segway Robot (autonomous robot based on the Segway miniPro)
Consumer
  • Ninebot by Segway E+ (self-balancing scooter for general use)

  • E110S (battery electric motorcycle)
  • E125S (battery electric motorcycle)

Technology

The dynamics of the Segway PT are similar to a classic control problem, the inverted pendulum. It uses brushless DC electric motors in each wheel powered by lithium-ion batteries with balance achieved using tilt sensors, and gyroscopic sensors developed by BAE Systems' Advanced Technology Centre.

Usage

Two tourists on a Segway tour in Florence, Italy

In 2011, the Segway i2 was being marketed to the emergency medical services community.

In 2018, the police of Stockholm adopted Segway i2 as a permanent transportation method for the patrollers of the old town.

The Segway miniPro is also available to be used as the mobility section of a robot.

Disability Rights Advocates for Technology worked to supply Segway PTs to veterans who had trouble walking. (Segway Inc. cannot market its devices in the US as medical devices. Kamen sold the intellectual property rights for medical purposes to Johnson & Johnson, makers of the iBOT, a self-balancing wheelchair).

The maximum speed of the Segway PT is 12.5 miles per hour (20.1 km/h). The product is capable of covering 24 miles (39 km) on a fully charged lithium-ion battery, depending on terrain, riding style, and the condition of the batteries. The U.S. Consumer Product Safety Commission does not have Segway-specific recommendations but does say that bicycle helmets are adequate for "low-speed, motor-assisted" scooters.
