This is a box package with front and rear stabilizers for when you decide to park the machine and shut it off you're able to also recharge it then. This is for people who are handicapped that would like to be mobile with everybody else or maybe go for a bike ride with your family since the Segway travel at 12.5 mile an hour!! You can put any kind of seat on top of this box. This box mounts to the Segway I2 or X2. Please feel free to email me with any questions. Buyer is responsible for shipping cost. The Segway is not included it's just to show you how this box mounts and looks on one.
