P.U.M.A. Segway Advanced Development

Think of it as a digital solution to an analog problem. Segway's P.U.M.A. (Personal
Urban Mobility & Accessibility) prototype represents the shift that's needed for the future of transportation. It values less over more; taking up less space, using less energy, produced more efficiently with fewer parts, creating fewer emissions during production and operation, all while offering more enjoyment, productivity, and connectivity.

Take a test drive and you quickly understand that this is something completely different. The elegance and maneuverability of dynamic stabilization combined with proven battery, sensing, and controls technologies come together to solve real transportation challenges. This prototype represents only the first step of what's possible in a technology collaboration between Segway and General Motors.

The P.U.M.A. Prototype in Action

Project P.U.M.A. Prototype

Segway's Top Tech - Developments in our house are more than just taking existing technologies and slapping a battery on them. We develop systems; not individual components. It's a completely new approach that combines expertise in the following areas:

Dynamic Stabilization

That's fancy speak for the tech that enables balancing. It's proprietary and full of benefits such as incredible maneuverability (true zero turning radius), a small footprint and providing a fantastically unique riding experience.

Electric Propulsion

Electric Propulsion

Besides being clean and extremely efficient, electric propulsion enables fine adjustments to be made to each wheel (for turning and smoothing out the ride), and a precise, software-based approach to traction control and braking.


Intuitive User Interfaces

When you feel it, you know it. Segway's approach to user control is that of minimalism and a natural connection between man and machine. Our innovative sensing technologies allow us to look beyond traditional controls that haven't changed dramatically since the introduction of the automatic transmission.

Smarty Battery Management

Smart battery management

Segway is one of the world's largest customers of large format batteries, and was at the forefront of the development of Lithium Ion batteries for transportation. We've learned a lot about the advanced sensing needed inside and applied this expertise to allow for more efficient energy use that leads to a longer battery life. Add in regenerative braking capability (being able to recharge while decelerating) and that's some smart battery tech.

Advanced Sensing

Advanced Sensing

If there's a feeling you get when trying a Segway product, it's like it can almost read your mind. Well, it's not magic. It's the combination of propulsion, energy, inertial sensing and an incredibly intuitive user interface that enables a ride that will force you to hold back a smile. Hopefully someday you'll have a chance to try it out and feel good about your commute instead of fearing it.

Drive-by-wire

Drive-by-wire

Mechanical controls are so yesterday. We're all about using the latest in sensory technology to enable safe control through redundant systems that provide input for acceleration, braking, steering, and other functions.

Q: What are the specifications for this prototype?
A: Passengers: Currently configured for 2, but could carry more
Top speed: Aimed to travel between 25 and 35 mph (40 – 56 kph)
Range: Aimed to have a 25 – 35 mile range (40 – 56 km)
Weight: Currently ~300 lbs/136 kg
Key/system information: Wireless via handheld
Charge time: ~8-10 hours
Turning radius: Zero
(All specs are approximate and do not imply intended configuration if it or a variant were ever to productized.)

Q: How much does it cost in electricity to recharge?
A: Based on the current battery configuration, it's about $.60 in electricity to recharge.

Q: How do you accelerate?
A: Push the steering console forward to alter the position of the center of mass of the vehicle and it'll naturally accelerate forward.

Q: How does it brake?
A: Perform the opposite by pulling the steering console toward you.

Q: How does it balance?
A: It uses an array of angular rate sensors and accelerometers to determine the orientation and motion of the vehicle's platform. As the platform leans forward, the balance sensor assembly notices and responds by requesting power to the motors to drive the wheels forward to maintain balance.

Q: When can I get one?
A: This is only a prototype with no current plans to offer it for sale, but you can sign up for our company newsletter here to receive more information about Segway.

Q: In what weather conditions can this be ridden?
A: The prototype has not been tested in adverse weather. Additional development would be necessary to determine the proper enclosure to protect against the elements and maintain traction control.

Q: What sort of terrain does it travel over?
A: The prototype was developed to travel over smooth terrain as a demonstration of what's possible with existing technology.

Q: What would this cost if it were to come to market tomorrow?
A: Think about this prototype as building up from a Segway PT, not down from a car. As such, there are a lot of components that can be eliminated and cost saved. Still, batteries are a significant portion of any electric transportation product. Range configurations would sway any figure significantly. So we're not going to share a figure at this time, but it's probably less than most current small car prices.

Q: How can I get one?
A: There's only one in the world. If you'd like to sign up to keep informed about future updates, we recommend that you subscribe to our company newsletter, read the Segway blog, and follow us on Twitter.
