A suspension system for a vehicle comprising a wheel link floating pivot, a wheel rotation axis, a wheel link, a control link, a control link fixed pivot, a brake link, and a shock absorber; wherein said wheel link floating pivot is concentric with said wheel rotation axis; wherein said shock absorber is selected from the group consisting of a damper, a compression gas spring, a leaf spring, a coil spring, and a fluid; and wherein said shock absorber is mounted to a link selected from the group consisting of the brake link and the control link, such that said shock absorber is able to respond to movement of a rear wheel; wherein said brake link is pivotally connected to said control link; wherein movement of said control link about said control link fixed pivot consists of one degree of freedom; wherein as the suspension is compressed or extended, said shock absorber is compressed or extended, so that force that compresses or extends said shock absorber is transmitted through said brake link and said wheel link floating pivot; wherein said suspension system comprises a compressible wheel suspension travel distance that features a beginning travel point where the suspension is completely uncompressed to a point where no further suspension extension can take place, and an end travel point where a suspension is completely compressed to a point where no further suspension compression can take place; and wherein a leverage ratio curve of said suspension system has a negative or a positive slope in the beginning ⅓ (third) and in the end ⅓ (third), and a change in slope value in the middle ⅓ (third).

92. The suspension system of claim 91 , wherein force is transmitted to said shock absorber through said control link and a control link floating pivot.

93. The suspension system of claim 91 , said suspension system further comprising an instant force center that is in different locations when the suspension is fully compressed compared to the when the suspension is uncompressed.

94. The suspension system of claim 91 , wherein said leverage ratio curve of said suspension system has a negative slope in the beginning ⅓ (third) and a positive slope in the end ⅓ (third), and a change in slope value in the middle ⅓ (third).

95. The suspension system of claim 91 , wherein said leverage ratio curve of said suspension system has a positive slope in the beginning ⅓ (third) and a negative slope in the end ⅓ (third), and a change in slope value in the middle ⅓ (third).

96. The suspension system of claim 91 , said suspension system further comprising a removable pivot axle; wherein said removable pivot axle has a feature for positioning a rear hub in relation to a said wheel rotation axis, wherein said removable pivot axle can receive a thru axle selected from the group consisting of a solid axle, a thru axle, a hollow axle, a quick release, a skewer, a quick release skewer, and a through bolt.

97. The suspension system of claim 91 , said suspension system further comprising a rear hub, a derailleur hanger, and a brake mount, said derailleur hanger being adjacent to one side of said rear hub, and said brake mount and brake link being positioned adjacent to the opposite side of said rear hub; wherein said wheel link is mounted outboard of and adjacent to said brake mount and said brake link.
