                  Top speed and turning rate 
                   
                  The maximum forward speed and turning rate of your Segway PT 
                  can be set at different values based upon which key 
                  is used:

                    The range for the i180 Police varies with type of battery, terrain, 
                    riding style and payload. Under normal riding conditions, 
                    you can expect to ride within the range noted for that battery 
                    type.

                    When stored and charged at room temperature, the i180 Police can 
                    perform in a wide range of operating environments. Actual 
                    performance is dependent on battery temperature, terrain, 
                    riding style and payload.

                  The i180 Police's large tires and tall profile make it suitable for 
                  a wide range of applications and terrains. The Segway HT's 
                  inertial sensors constantly monitor the rider's position relative 
                  to gravity. This allows the Segway HT to adjust for changes 
                  in terrain while keeping the rider upright.

                    The i180 Police can accommodate up to 260 lbs., including cargo in the 25.0 Side Cargo and 12.0 Handlebar bags.

                    We designed the Segway PT to take up no more space than the 
                    average person. About as wide as the average person's shoulders, 
                    it raises you 8 inches off the ground, providing a clear sight 
                    line of your surroundings.

                  Portability was a key design objective. That's why we made 
                  the Segway PT light enough to handle, small enough to store in the 
                  trunk of a midsize sedan, and collapsible enough to fit in 
                  tight storage spaces.

                  One characteristic of a pedestrian is the ability to turn in 
                  place without impacting any nearby person or object, something 
                  few vehicles can do. By balancing on a single axle, Segway PT 
                  riders can also turn in place.

                  Lithium-ion (Li-ion) Battery Packs 
                  The i180 is one of the first Segway PTs that comes with optional 
                    Saphion lithium-ion battery packs. The batteries are designed 
                    with on-board electronics that automatically monitor both 
                    the condition and temperature of the batteries. Batteries 
                    can be recharged by utilizing any 90 to 260 volt and 50 to 
                    60 Hz AC outlet (typically accessible in most countries). 
                    A complete cycle charge will take eight to ten hours, which 
                    at 10 cents per KW-h, equates to less than 10 cents of electricity. 
                    Li-ion batteries are designed for approximately 300-500 full 
                    charge/discharge cycles. 
                  Range, battery life and recharge times can be affected by 
                    factors such as terrain, temperature, speed of operation, 
                    rider weight and load, proper storage techniques and environmental 
                    conditions.

                  Redundant electrical systems.  
                  Robust mechanical systems. 
                   
                  Safety is our top priority in both design and operation. To 
                  help ensure that both Segway PT users and those near them remain 
                  safe, we built redundancy into the balancing and electrical 
                  systems. If any system begins operating at diminished capacity, 
                  the other is programmed to assume responsibility. This allows the Segway PT to 
                  maintain balance and bring the rider to a safe stop.
The highest design standards were implemented in building the Segway 
                    PT's mechanical structures, and each part has been thoroughly 
                    tested and analyzed to ensure such high standards were met.
