| Abstract: |
A multi-wheeled cycle comprising a frame, a main wheel, and at least one auxiliary wheel secured for rotation at one end of the frame forwardly or rearwardly of the main wheel, and a spaced-apart pair of auxiliary wheels secured for rotation at the other end of the frame rearwardly or forwardly of the main wheel. The main wheel is held for rotation to the mid-portion of the frame and includes a conventional crank and pedal assembly for foot rotation of the main wheel while the user is seated atop the cycle. The bottom of the main wheel lies below the plane defined by the bottoms of the auxiliary wheels to facilitate unique maneuvering and operation. The main wheel may also be pivotable about a vertical axis passing through it. All axes of rotation of the wheels are generally horizontal.

What is claimed is:
1. A multi-wheeled cycle operable as a unicycle comprising:
- a frame having a mid-portion and first and second portions extending from said mid-portion in opposite directions;
- a vertical axis extending through said mid-portion of said frame at the center thereof;
- said frame mid-portion including a user support means located on said vertical axis for supporting the user while seated with legs astride said frame;
- a main wheel rigidly connected for rotation to, and disposed from, said frame mid-portion in a fork;
- said fork being generally upright, located on said vertical axis and having an upper end, and said main wheel having a horizontal axis located on said vertical axis;
- a collar on said frame mid-portion having a vertical portion for receiving and supporting said upper end of said fork;
- said main wheel having opposing pedals disposed from a crank operatively connected to said main wheel on said horizontal axis for propelling said cycle;
- at least one auxiliary wheel rigidly connected for rotation to said frame first portion;
- at least two spaced apart auxiliary wheels rigidly connected for rotation to said frame second portion;
- the axes of rotation of said auxiliary wheels generally horizontal and parallel;
- the bottom of said main wheel lying below the plane formed by the bottoms of said auxiliary wheels.
