This is a Segway a i180. I am the second owner and have owned it since 2011. When I bought the unit the batteries were no good. I spent over $1,000 to have the batteries rebuilt, and to a higher amp hour life. The Segway is capable of 20 + miles on its current batteries. Everything on the Segway is still in good shape. The tires still have plenty of tread. The Segway also comes with an accessory bar with a bag which is capable of carrying many items. The bag is also removable and becomes a carry bag. I have all three keys for the Segway. I also have the original box and packing material. I used the Segway as a handicap transport. I was looking for something more portable. That is why I am selling the unit. This unit has lithium ion batteries. I will pay for shipping.
