Segway
battery-powered electric vehicle
The Segway ( SEG-way) was a two-wheeled, self-balancing personal transporter 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 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 manufacture 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 the University of Plymouth in conjunction with BAE Systems and Sumitomo Precision Products. The first patent for a 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. Steve Jobs was quoted as saying that it was "as big a deal as the PC".
This brief starts where responsible research should: with the source description of “Segway” as battery-powered electric vehicle. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as battery-powered electric vehicle. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q214893. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2001, 2015, 2020 and 1994.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
