A bicycle frame is disclosed. In certain examples, the bicycle frame includes a head tube coupled to a top tube and a down tube, a seat tube coupled to the top tube and the down tube, and an upper pivot point disposed in the seat tube configured to pivotally couple to a rear suspension system. In certain examples, the bicycle frame includes a plurality of lower pivot points disposed in the seat tube configured to pivotally couple to the rear suspension system, each of the plurality of lower pivot points causing, when coupled to the rear suspension system, the rear suspension system to define a different wheel path as a rear wheel of the rear suspension system travels from an extended position to a compressed position.

The invention relates to a variable-geometry bicycle frame. The bicycle frame consisting of a bearing element (1) comprises a front fork mount (2) and a crankset mount (3), a seat constructional part (10) comprises a saddle’s (4) clamp, an adjustment part (7), a rear wheel suspension set (20) comprises a swingarm (21) and a shock absorber (22) characterized in that, the bearing element (1) is connected by at least one articulated joint to the seat constructional part (10) and by at least one articulated joint to the rear wheel suspension set (20), and the seat constructional part (10) is connected by at least one articulated joint to the rear wheel suspension set (20) and the adjustment part (7) is movable within the range from the X position to Y position.

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.

A pedal driven cycle comprising a cantilevered frame member coupled to a power input sprocket and a driven sprocket; a belt drive connecting the power input sprocket to the driven sprocket; and a side mounted rear wheel releasably coupled to a multi-speed gear hub that is coaxial with the side mounted rear wheel, wherein the multi-speed gear hub is coupled to the driven sprocket.

A bicycle frame is discussed having a battery fully contained within a down tube of the bicycle frame. The battery may be inserted into or removed from the down tube via a through opening through a bottom bracket housing of the bicycle frame. Weakness in the bottom bracket housing due to the through opening may be compensated for, fully or partially, by utilizing a bottom bracket bearing assembly that has a structural component, or structural component assembly, that extends completely through the bottom bracket housing and removably couples to the bottom bracket housing.

A method of making a bicycle frame includes placing an impact resistant film into one or more portions of a bicycle frame mold. The method also includes placing a plurality of layers of carbon fiber into the bicycle frame mold. The method further includes applying heat to the bicycle frame mold to form a bicycle frame that has an exterior surface, wherein at least a portion of the exterior surface is covered by the impact resistant film.

A bicycle frame includes a top tube that connects to a head tube at a front portion of the bicycle frame. The bicycle frame also includes a first seat stay that connects to the top tube at a first point of intersection and a second seat stay that connects to the top tube at a second point of intersection such that a back portion of the top tube extends beyond the first point of intersection and the second point of intersection so that the top tube is a cantilever. The bicycle frame also includes a seatmast sized to receive a seatpost. The seatmast extends from the back portion of the top tube that forms the cantilever.
