Abstract
A bicycle assembly can include a bicycle frame that can have a main frame, a sub-frame and a shock absorber. The sub-frame can move in relation to the main frame and the shock can be used to regulate that relationship. A extension body can be used to establish a rear pivot point of the shock absorber. In some embodiments, the extension body can also be used to adjust the length of the combined shock absorber and extension body.
Claims16
A bicycle assembly comprising:
- a main frame comprising a seat tube, a head tube and an intermediate tube connecting the seat tube and the head tube;
- a sub-frame configured to rotate with respect to the main frame, the sub-frame comprising a pair of seat stays and a pair of chain stays;
- a shock absorber having first and second opposing ends and a first eyelet connected to the main frame at the first end and a second eyelet at the second end, the shock absorber defining an axis between the first and second end;
- and
- an extension body comprising a first end and a second end, wherein the second eyelet at the second end of the shock absorber is positioned within the first end of the extension body and the second end of the extension body forming a rear pivot of the shock absorber, a front pivot of the shock absorber being at the first eyelet of the shock absorber, the shock absorber and extension body configured to regulate a positional relationship between the main frame and the sub-frame;
- wherein the first end of the extension body receives the second eyelet within the extension body and the axis of the center of the second eyelet is offset from the axis of the center of the first eyelet.

A bicycle assembly comprising:
- a main frame comprising a seat tube, a head tube, a top tube, and a bottom tube, the top and bottom tubes connecting the head and seat tubes;
- a sub-frame configured to rotate with respect to the main frame, the sub-frame comprising a pair of seat stays and a pair of chain stays, each chain stay pivotally connected to one of the seat stays;
- a shock absorber having first and second opposing ends and a first eyelet connected to the main frame at the first end and a second eyelet at the second end, the shock absorber defining an axis between the first and second end;
- and
- an extension body comprising a first end and a second end, wherein the second eyelet at the second end of the shock absorber is positioned within the first end of the extension body and the second end of the extension body forming a rear pivot of the shock absorber, a front pivot of the shock absorber being at the first eyelet of the shock absorber, the shock absorber and extension body configured to regulate a positional relationship between the main frame and the sub-frame;
- wherein the first end of the extension body receives the second eyelet within the extension body and the axis of the center of the second eyelet is at least about 15 degrees offset from the axis of the center of the first eyelet.
