Segway I170 Electric Scooters

*Top speed: 12.5 miles per hour (20 kph). This is about three times  typical walking speed.
*Weight: 80 lbs (36 kg)
*Width:TheSegway'sfootprint (how much space it covers on the ground)  is 19by 25inches(48 by 63.5 cm). This makes the Segway about the  samewidth asanaverage size person, so it doesn't take up much space  onthe street.Theplatform is 8 inches (20 cm) off the ground.
*Weight capacity: 250 pound (110 kg) person with 75 pounds (34 kg) of  cargo.
*Range:About17miles (28 km) on even ground, with a single charge. Takinguneventerrain into account, Segway's designers estimate the vehiclehas arange of 11 miles (17 km) on a single charge.
*Driverinterface:TheSegway has a small LCD screen that tells the  driver howmuchbatterypower is left and how well the vehicle is  functioning.Thescreendisplays a cartoon face, which expresses the  generalcondition ofthevehicle. The driver interface is designed to  besimple and intuitive.
*Motors: Each of the Segway's wheels is driven by a 2horse power   electric motor that produce no emissions.
*Transmission:Thetwostage transmission, built by Segway and Axicon  Technologies,hasacompact 24:1 gear ratio. It uses a helical gear assemblythatsignificantly reduces noise. The Segway team configured the twomeshesin the gear box (the points where gears connect) to  makesoundexactly two octaves apart.
*Computer: The Segway's brainismadeup of two circuit boards, housed  in the vehicle's chassis.Thecircuitboards, which boast a total of  10 microprocessors,normallyworktogether, but each can function  independently in the eventofacomputer problem. If one breaks, the  other circuit board willslowthevehicle down gradually to avoid an  accident.
*Power: TheSegwayispowered by two rechargeable batteries. Segways  come witheithernickelcadmium (NiCd) or nickel metal hydride (NIMH)   batteries.
*Sensors:TheSegwayuses five gyroscopes and a collection of other  tilt sensorstokeepitself upright. Only three gyroscopes are needed   theextrasensors areincluded as a safety precaution. The Segway has anadditional weightsensor built into its platform to tell the computerwhen a rider hasstepped on.
*Brakes: The Segway doesn'thave abraking system. Tostop, the rider  stands upright withoutleaningforward or backward, andthe vehicle  maintains its position.
*Turningradius:Since it onlyhas two wheels, the Segway can rotate  around asingleaxis (the wheelsturn in opposite directions). This  gives theSegway aturning radius ofzero.
*Wheels: The Segway wheel consistsof aforged steel wheel hubwith  glass reinforced thermoplastic rim.Eachwheel is secured to thedrive  shaft with a single nut. The tiresaremade of a silica compound, which provides good traction even onwetsurfaces.
*Security: TheSegway uses an electronic key system.Thekey, which  looks somethinglike a car lighter, stores a 128bitencrypted digital  code. The vehiclewon't start unless the keyisplugged into its port.
*Chassis: The Segway's sensitive electronic equipment is housed in a   sturdy die cast aluminum chassis.
*Controlshaft: The aluminum shaft that holds up the Segway's    handlebars canbe adjusted to different heights. Business Card Business Card
