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.
Claims1
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;
- a shock absorber having first and second opposing ends and first and second eyelets at each end, the first eyelet at the first end connected to the main frame;
- and
- an extension body comprising a first end connected to the shock absorber at the second eyelet and a second end comprising a pair of extension arms, each extension arm connected to the sub-frame, wherein a rear pivot of the shock absorber is defined by a connection point between each extension arm and the sub-frame, and the rear pivot configured to be at the sides of a rear wheel;
- 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, such that the extension body forms a rigid, non-rotating connection with the second eyelet.
