[6] Prior to its introduction, a news report[7] about a proposal for a book about the invention, development, and financing of the Segway PT [8] led to speculation about the device and its importance.

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.

[16] 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,[17] 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.

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.

A year later, Heselden died after he "plunged into the River Wharfe while riding a rugged country version" of Segway PT.

[24][25] 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.

[1] 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.
