Segway Inc. is an American manufacturer of two-wheeled personal transporters, chiefly through its Segway PT and Segway miniPro product lines. Since 2015, it has been owned by the Chinese company Ninebot. Founded by inventor Dean Kamen in 1999, the company's name is a homophone of the word "segue".
Segway Inc. is headquartered in the U.S. state of New Hampshire and primarily markets its products to various niche markets, including police departments, military bases, warehouses, corporate campuses, and industrial sites. It has held some key patents on designs for self-balancing personal transporters, although some of them have since expired. Since being acquired by Ninebot, Segway Inc. has focused on developing a stronger presence in the consumer market with smaller products such as the Segway miniPro.
The first patent by Dean Kamen for a self-balancing transportation device was filed on February 23, 1993, and granted on December 30, 1997, in relation to the iBOT, a self-balancing wheelchair which he developed at DEKA, a company that he had founded in 1982. That patent has since expired, although it was followed by various others, and some patents assigned to the company have not yet expired (as of early 2019).
Development of the iBOT started in 1990 with the first working prototypes available in 1992. In late 1994, DEKA signed a deal with Johnson & Johnson to manufacture the unit, with Johnson & Johnson paying for all subsequent R&D with DEKA received a smaller royalty fee than normal in return for their retaining rights to all non-medical applications of the technology. The iBOT was revealed to the public on Dateline NBC in a segment by John Hockenberry on June 30, 1999.
Segway Inc. was founded in July 1999 to develop non-medical applications for the self-balancing technology, and the Segway PT, a two-wheeled personal transporter, was launched in December 2001, with first deliveries to customers in early 2002.
When it was launched in December 2001, the annual sales target was 40,000 units, and the company expected to sell 50,000 to 100,000 units in the first 13 months. By 2003, the company had sold 6,000 units, and by September 2006 approximately 23,500, when all units sold up to that point were recalled due to a software glitch that could cause the units to reverse, potentially causing riders to fall off. In a March 2009 interview, a company official said the firm "has shipped over 50,000" Segway PTs.
Segway Inc's investors remained optimistic. Dean Kamen predicted that the Segway "will be to the car what the car was to the horse and buggy" and John Doerr, a venture capitalist who invested in the company, predicted that Segway Inc would be the fastest company to reach US$1 billion in sales.
By 2007, cumulative sales were 30,000 units. Critics pointed to Segway Inc's silence over its financial performance as an indication that the company was still not profitable, following expenditure of some US$100 million developing the Segway PT.
In 2009 General Motors announced that it was building a prototype two-seat electric vehicle with Segway. An early prototype of the Personal Urban Mobility and Accessibility vehicle, dubbed Project P.U.M.A., was demonstrated in New York a day ahead of the press previews for the 2009 New York International Auto Show. At Expo 2010 in Shanghai, the successor was presented, the "EN-V project".
James Norrod served as the President and Chief Executive Officer of Segway Inc. from April 2005 to January 2010 and steered the sale of the company to a group led by British millionaire Jimi Heselden, chairman of Hesco Bastion in December 2009. After the sale, Dean Kamen was no longer involved with the company.
The new owner died in 2010 when he drove off a cliff while riding a Segway.
In February 2013, Summit Strategic Investments, LLC, announced it had acquired the company, saying that it planned to refocus, grow its product portfolio and expand its worldwide network. In September 2014, Segway filed a complaint with the United States International Trade Commission about the infringement of several of its patents by several Chinese companies, including Ninebot, Shenzhen INMOTION Technologies and Robstep Robot.
