BEDFORD— Segway Inc. is celebrating the 10th anniversary of its Personal Transporter, unveiled on “Good Morning America” in December 2001.

The electric, two-wheeled, self-balancing transportation device, which became available to customers in 2002, has expanded over the decade into international, robotics, public safety and tourism markets.

A company spokesman told the New Hampshire Union Leader in an email Tuesday that Segway has sold “close to 100,000 Personal Transporters” during the decade. Segway, a private company, routinely does not disclose sales figures or revenues or financial details.

Segway Tours stores operate in a dozen markets in the U.S. and Canada, including one on Hanover Street in Manchester.

The company, founded by inventor Dean Kamen, has expanded its sales outlets to Europe, the Middle East, Asia and Africa, and Segway PTs have been deployed in more than 1,200 police departments and public safety organizations worldwide, Segway said in a news release.

The company was acquired in 2010 by James “Jimi” Heselden, a British entrepreneur and owner of Hesco Bastion, who accidentally drove one of the vehicles over a cliff in West Yorkshire, England in September 2010 and plunged to his death.

Segway, based in Bedford, has a network of more than 250 distributors, dealers and experience centers in 80 countries.
