| Abstract: |
A bicycle with an eccentric rear wheel including a inner rim with two plates set in parallel with each other across a diameter of the inner rim and an outer rim. A sleeve with a seat formed on it is provided around a hub of the eccentric wheel and serves to receive a shaft head extending from one end of a threaded shaft. The threaded shaft has a pinion on an end thereof opposite to said shaft head. Toothed blocks are slidably mounted on each seat stay to be engageable with the toothed pinion so as to cause the wheel to rotate more or less eccentrically about the hub.

I claim:
1. A bicycle having a frame, a seat, a front wheel, a couple of seat stays and a rear wheel, characterized in that:
- said rear wheel has an inner rim with two plates set in parallel with each other across a diameter of said inner rim and an outer rim, a plurality of spokes being radially oriented between said inner rim and outer rim;
- a sleeve with a seat formed thereon is provided around a hub of said eccentric wheel; said sleeve receiving a shaft head extending from one end of a threaded shaft, said threaded shaft being threadably positioned between said two plates by two nuts which are fixed between said two plates and against respective supporting means which are positioned between said two plates in appropriate position, said threaded shaft having a pinion on an end thereof opposite to said shaft head; and
- respective toothed blocks are slidably mounted on each seat stay to be engageable with said toothed pinion; said toothed blocks being slidable to adjust a relative position of said hub with respect to said plates by engaging with and rotating said pinion so as to cause said wheel to rotate more or less eccentrically about said hub.
