a rear frame coupled to the front frame at two connections; a link creating a first connection of the two connections, the first connection defines a pivotal connection between the front frame and the rear frame; and a shock absorber creating a second connection of the two connections, the shock absorber having a first section translationally moveable relative to a second section of the shock absorber, and a first end of the first section is fixedly connected to the front frame and a second end of the second section is rotationally connected to the rear frame. ### Claim 2 (depends on 1) The bicycle suspension of claim 1, wherein the front frame comprises a linear form in which a portion of the shock absorber is positionable therein and extending out of. ### Claim 3 (depends on 2) The bicycle suspension of claim 2, wherein the front frame comprises a structure defining a closed shape in which an angled portion of the front frame extends from the linear form and away from the shock absorber at an end of the linear form in which the shock absorber extends, the angled portion forming an angle relative to the linear form to permit a linear extension and contraction of the shock absorber. ### Claim 4 (depends on 1) The bicycle suspension of claim 1, wherein the front frame defines a closed shape having a first apex of the closed shape adjacent to or comprising a bottom bracket, and a second apex of the closed shape configured to support a head tube for connection to a front wheel, wherein the closed shape is rigid and the first section of the shock absorber is integrated into a portion of a side defining the closed shape to rigidly couple the first section to the front frame. ### Claim 5 (depends on 1) The bicycle suspension of claim 1, wherein the front frame defines a generally triangular shape that has a first apex of the generally triangular shape adjacent to or comprising a pivotal attachment to the link, and a second apex of the generally triangular shape configured to support a head tube for connection to a front wheel, wherein the generally triangular shape is closed and rigid and the first section of the shock absorber forms part of the closed shape of the front frame to rigidly integrate the first section of the shock absorber to the front frame. ### Claim 6 (depends on 1) The bicycle suspension of claim 1, wherein the link has a first end and a second end, the first end pivotally coupled to the front frame and the second end pivotally coupled to the rear frame. ### Claim 7 (depends on 1) The bicycle suspension of claim 1, wherein the link comprises a bottom bracket. ### Claim 8 (depends on 1) The bicycle suspension of claim 1, wherein the front frame comprises a bottom bracket and the link is rotationally coupled to the front frame adjacent to the bottom bracket. ### Claim 9 (depends on 1) The bicycle suspension of claim 1, wherein the front frame comprises a bottom bracket and the link is rotationali coupled to the front frame concentric with the bottom bracket. ### Claim 10 (depends on 1) The bicycle suspension of claim 1, wherein the rear frame comprises a generally triangular shape that has a first apex having a first connection configured to carry a rear wheel having a rear wheel axis, a second apex having a second connection to the shock absorber, and a third apex. ### Claim 11 (depends on 10) The bicycle suspension of claim 10, wherein a third connection to the link is at or adjacent to the third apex. ### Claim 12 (depends on 1) The bicycle suspension of claim 1, wherein the first section of the shock absorber is integrated into the front frame, such that the front frame and the first section of the shock absorber define a rigid structure. ### Claim 13 A bicycle suspension, comprising: a front frame having a bottom bracket; a rear frame coupled to the front frame at two connections; a link creating a first connection of the two connections, the first connection defines a pivotal connection between the front frame and the rear frame, and the link is rotationally coupled to the front frame adjacent to the bottom bracket; and a shock absorber creating a second connection of the two connections, the shock absorber having a first section translationally moveable relative to a second section of the shock absorber, and a first end of the first section is fixedly connected to the rear frame and a second end of the second section is rotationally connected to the front frame. ### Claim 14 (depends on 13) The bicycle suspension of claim 13, wherein the rear frame comprises a linear form in which a portion of the shock absorber may be positioned therein and extend out of. ### Claim 15 (depends on 13) The bicycle suspension of claim 13, wherein the front frame defines a generally triangular shape that has a first apex of the generally triangular shape adjacent to or comprising the bottom bracket, and a second apex of the generally triangular shape configured to support a head tube for connection to a front wheel. ### Claim 16 (depends on 13) The bicycle suspension of claim 13, wherein the front frame defines a generally triangular shape that has a first apex of the generally triangular shape adjacent to or comprising a pivotal attachment to the link, and a second apex of the generally triangular shape configured to support a head tube for connection to a front wheel. ### Claim 17 (depends on 13) The bicycle suspension of claim 13, wherein the link has a first end and a second end, the first end pivotally coupled to the front frame and the second end pivotally coupled to the rear frame. ### Claim 18 (depends on 13) The bicycle suspension of claim 13, wherein the rear frame comprises a generally triangular shape that has a first apex having a first connection configured to carry a rear wheel having a rear wheel axis, a second apex having a second connection to the shock absorber, and a third apex. ### Claim 19 (depends on 18) The bicycle suspension of claim 18, wherein the rear frame has a third connection to the link at or adjacent to the third apex.
