| Abstract: |
Tubular spacers (28) are positioned between the wheels (10, 12) of a unicycle. Inboard portions of tie bolts (34) extend through the spacers (28). A threaded end portion (38) of the tie bolt (34) screws into a T-nut (40) provided within an opening (26) in a wheel (12). The shaft of the tie bolt (34) projects through an opening (24) in the other wheel (10) and projects outwardly beyond the wheel (10). A second tubular spacer (50) closely surrounds the outboard portion of the tie bolt (34). At one end (52) this spacer bears against an abutment (46). At its opposite end (54) it abuts against the inner surface of the tie bolt head (36). When the tie bolt (34) is tightly screwed into the T-nut (46), it is put into tension and the tubular spacers (28, 50) are put into compression. A pedal element (56) is mounted for rotation about the outboard tubular spacer (50).
