Abstract: A bicycle includes a chainstay protector having an upper surface including a valley, a first peak, and a second peak. The first peak extends upwardly from the valley toward the chain and has a first contact surface positioned to contact the chain a first height above the valley. The second peak extends upwardly from the valley toward the chain and has a second contact surface positioned to contact the chain a second height above the valley. The first contact surface is spaced from the second contact surface by a gap that is at least 5 times the first height. Each of the first and second contact surfaces has a length that is less than the length of the gap and less than two times a pitch of the chain.

Abstract: A bicycle includes a frame having cross sectional profiles. The profiles are designed according to certain criteria to enhance bicycle performance. The profiles for multiple frame members may each fall within a range for each of aspect ratio, circumference, drag coefficient, first moment of inertia and/or second moment of inertia.

Abstract: A suspension assembly for a cycle includes a plurality of links pivotably connected to one another by a plurality of pivots. A rotation sensor measures an angular relationship between two links and a setpoint of the suspension assembly is adjusted based on the angular measurements.

Abstract: A bicycle assembly can include a bicycle frame having a main frame and a sub-frame, and a shock absorber assembly. The shock absorber assembly can comprise a shock absorber and an extension body. The sub-frame can rotate in relation to the main frame and the shock absorber assembly can be used to regulate that relationship. An eccentric insert positioned functionally between the shock absorber and extension body can be used to modify the overall length of the shock absorber assembly to beneficially alter the geometry of the bicycle frame.

A shock link has a shock link fixed pivot and a shock link floating pivot. A shock absorber has a shock gas spring comprising a shock spring body a shock gas piston having a first gas piston area, a spring unit has a spring gas spring comprising a spring body and a spring gas piston having a second gas piston area. The first gas piston area is not equal to the second gas piston area.

Abstract: A bicycle saddle includes: a base structure having a top portion; and a cushion coupled to the top portion of the base structure, the cushion including a first lateral side and a second lateral side separated by a longitudinal plane, wherein each of the first lateral side and the second lateral side includes: a first region having a first stiffness; a second region having a second stiffness that is less than the first stiffness; and a third region having a third stiffness that is less than the second stiffness, wherein a perimeter of the second region is at least 75% enclosed within the first region, and wherein a perimeter of the third region is at least 75% enclosed within the second region.

Abstract: A bicycle assembly can include a bicycle frame having a main frame and a sub-frame, and a shock absorber assembly. The shock absorber assembly can comprise a shock absorber and an extension body. The sub-frame can rotate in relation to the main frame and the shock absorber assembly can be used to regulate that relationship. An eccentric insert positioned functionally between the shock absorber and extension body can be used to modify the overall length of the shock absorber assembly to beneficially alter the geometry of the bicycle 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.

Abstract: A bicycle includes a front wheel; a rear wheel; a frame including a main frame portion and an articulating frame portion, the articulating frame portion including an upper frame link pivotally supported at a first axis by the main frame portion; and a lower shock link pivotally coupled to the main frame portion at a second axis; and a shock absorber having a first end pivotally supported by the main frame portion, and a second end pivotally supported by one or both of an upper shock link and the lower shock link, wherein, when the bicycle is positioned on a horizontal surface with the articulating frame portion in a relaxed configuration, the second axis is positioned forward of the first axis.

Abstract: A bicycle includes a frame, a suspension assembly and a steering assembly. The frame includes a head tube that rotatably receives a front fork assembly. A steerer tube extends axially away from a fork crown of the front fork assembly. The suspension assembly includes an upper tubular support longitudinally slidable relative to a lower tubular support. The upper and lower supports receive a first positive biasing means and a first negative biasing means. The lower and upper supports are respectively connected to the steerer tube and a stem of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.

Abstract: A bicycle according to the present disclosure comprises a frame assembly and a front fork. The frame assembly includes a head tube defining a steering axis. The front fork is rotatably coupled to the head tube and includes upper and lower supports aligned with the steering axis. The upper and lower supports project away from the fork assembly and rotationally couple the front fork assembly to the head tube. A buttress is coupled to the upper and lower supports at upper and lower buttress ends. A pair of laterally spaced fork legs project from the buttress lower end at one end of the fork legs. The buttress is disposed forward of the head tube and has a lateral width which tapers from a first width at the buttress lower end to a second width at the buttress upper end.

Abstract: A suspension assembly for a bicycle comprises a lower tubular support configured to be received within a steerer tube of a bicycle fork assembly; an upper tubular support configured to be connected to a stem of a steering assembly above an upper end of the steerer tube; and a spring configured to exert a force that biases the upper and lower tubular supports toward an extended position, wherein the upper and lower tubular supports are configured such that the upper tubular support slides longitudinally relative to the lower tubular support adjacent the stem and above a fork crown of the bicycle fork assembly.
