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.
