| Abstract: |
A trailer for a dynamically balanced transporter that allows leaning of the transporter such as for control of the combination of transporter and trailer. The trailer has a platform and an arm with two ends, one of which ends is coupled to the platform and the other of which is pivotally coupled about a horizontal axis to the transporter. The trailer has a ground-contacting member that may be a wheel, or a ski or a skid. A locking mechanism may lock the pivot in response to a fault condition. The platform of the trailer may support a rider in a seated or standing position and may have a characteristic transverse linear dimension comparable to the shoulder width of the rider.

What is claimed is:
1. A trailer for carrying a user behind a dynamically balanced transporter, the trailer comprising:
- a) a platform for supporting the user in a standing position;
- b) a ground-contacting member supporting the platform, the ground-contacting member capable of swiveling about a vertical axis in a first rotation direction;
- c) a pivot arm having a pivot end with a pivot and a trailer end, the trailer end coupled to the platform, the trailer end capable of swiveling about a trailer end vertical axis in a trailer end rotation direction; and
- d) a scissor linkage coupled to the pivot arm and ground contacting member so that the first rotation direction is counter to the trailer end rotation direction.
