The Segway is a two-wheeled, self-balancing personal transporter invented by Dean Kamen and brought to market in 2001 as the Segway HT, subsequently as the Segway PT, and manufactured by Segway Inc. HT is an initialism for "human transporter" and PT for "personal transporter."


History

Independent company

The Segway PT, referred to during development and init porter}}</ref> 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 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", (but later retracted that, saying that it "sucked", presumably referring to "the design" but commenting about the boutique price, 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 models featured three speed settings: 6 miles per hour (9.7 km/h), 8 mph (13 km/h) with faster turning, and 10 mph (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 mi (9.7–16.1 km) on a fully charged nickel metal hydride (NiMH) battery with a recharge time of 4–6 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. With a software patch to version 12.0, the PT would automatically slow down and stop in response to detecting low battery power.

In August 2006, Segway 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 2 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 8–10 hours. The i2 and x2 also introduced the wireless InfoKey which could show mileage and a trip odometer, and put the Segway 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 police in Stockholm, Sweden.

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 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 Inc., a Beijing-based transportation robotics startup and a Segway rival, acquired Segway in April 2015, having raised $80M from Xiaomi and Sequoia Capital.

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

End of production

In June 2020, Ninebot, the owner of the Segway brand, announced that it would no longer make the namesake two-wheeled, self-balancing product.

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 which has led to notable accidents involving Usain Bolt, George W. Bush and the Segway Company owner Jimi Heselden. While the Segway has remained popular for security and tourism, electric scooters have been more popular for personal mobility.

Products

At the end of production in 2020, Segway was selling the following five following self-balancing scooters. (For other Segway products see Segway Inc.)

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)
  • Ninebot by Segway miniPro (smaller self-balancing scooter for general use, controlled by a 'knee control bar')

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. The wheels are driven forward or backward as needed to return its pitch to upright.

Usage

In 2011, the Segway i2 was being marketed to the emergency medical services community. In 2018, the police of Stockholm adopted Segways 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 mi (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.
