Abstract: A bicycle assembly can have a main frame, a subframe, and a shock absorber. The subframe can move in relation to the main frame, and the shock absorber can be used to regulate that relationship. A linkage can be connected to the shock absorber, the main frame, and a chain stay of the subframe to drive the shock absorber as the subframe is moved with respect to the main frame.

Abstract: A bicycle comprises a front wheel; a rear wheel; a frame comprising a main frame portion and an articulating frame portion, the articulating frame portion comprising: a lower arm pivotally supported at a first axis by the main frame portion; an upper frame link pivotally supported at a second axis by the main frame portion; an upper arm pivotally coupled to the upper frame link at a third axis; an upper shock link pivotally coupled to the upper frame link and the upper arm at the third axis; and a lower shock link pivotally coupled to the main frame portion and the lower arm at the first axis; and a shock absorber having a first end pivotally supported at a fourth axis by the main frame portion, and a second end pivotally supported at a fifth axis by the upper shock link and the lower shock link.
