## Abstract

A water shield structure for a transportation device and the transportation device having such a water shield structure. The transportation device is preferably a self-balancing device and may include a friction drive motor. The water shield structure helps reduce the entry of moisture from a riding surface into the wheel envelope or drive mechanism of the device. The water shield structure may extend laterally from a wheel and be enclosed, at least in part, in a housing.

## Claims

### Claim 1

A transportation device, comprising:
a first wheel structure including a first rim structure and a first tire;
a friction drive motor having a drive head, the drive head being in contact with a drive surface associated with the rim structure;
a foot platform for receiving the feet of a rider; and
a water shield member extending laterally from one side of at least one of the first rim structure and the tire and configure to impede the movement of water from the wheel structure to the drive surface when the device is used in wet conditions.
