Frame assembly for a bicycle |
摘要 |
A frame assembly for a bicycle having a front wheel and a rear wheel. The frame assembly preferably includes a main frame and a sub-frame, which is movable relative to the main frame and configured to carry the rear wheel. A shock absorber extends between and is connected to the main frame and the sub-frame. The main frame includes a down tube and a monolithic bottom bracket support. The monolithic bottom bracket support is connected to a rearward end of the down tube and preferably includes an opening configured to support a pedal crank assembly for rotation about a crank axis. Preferably, the shock absorber is connected to the main frame for rotation about a pivot axis positioned forward of the opening of the bottom bracket support. Desirably, the shock absorber pivot axis is positioned forward of a line passing through the crank axis and a center point of the down tube at the junction of the down tube and the head tube. In one arrangement, the monolithic bottom bracket support surrounds a portion of the shock absorber.
