         12 . The stroller of  claim 2 , wherein the rear wheel support is pivotable with respect to a frame of the stroller. 
     
     
         13 . The stroller of  claim 1 , further comprising a pivot anchor assembly comprising a first portion adjacent to a second portion and being spaced from the second portion along the pivot axis, the pivot member extending between the first portion of the pivot anchor assembly and the second portion of the pivot anchor assembly. 
     
     
         14 . A stroller comprising:
 a first rotatable plate comprising a first central aperture and a first planar arm projecting from the first rotatable plate; and   a pivot member, wherein the first rotatable plate is rotatably mounted on the pivot member, the pivot member comprising a rear wheel support for the foldable stroller, the pivot member comprising:
 a bushing that extends through the first central aperture; 
 wherein when the first rotatable member is in a stationary position, a second rotatable member is also in a stationary position via a retractable tip extended from the pivot member. 
   
     
     
         15 . The stroller of  claim 14 , further comprising:
 the second rotatable plate comprising a second central aperture and a second planar arm projecting from the second rotatable plate;   wherein the first rotatable member and second rotatable member pivot about the pivot member, and the retractable tip is manipulated by a lever adjacent to the rear wheel support.   
     
     
         16 . The stroller of  claim 14 , further comprising:
 a front wheel support;   at least one front wheel coupled to the front wheel support;   a rear wheel support;   at least one rear wheel coupled to the rear wheel support; and   a handle member.   
     
     
         17 . The stroller of  claim 15 , wherein:
 the front wheel support is coupled to one of the first rotatable member, the second rotatable member, and the pivot member;   the rear wheel support is coupled to a different one of the first rotatable member, the second rotatable member, and the pivot member that the front wheel support; and   the handle member is coupled to another different one of the first rotatable member, the second rotatable member, and a third rotatable member than the rear wheel support.   
     
     
         18 . The stroller of  claim 14 , wherein the bushing facilitates a symmetric rotation of the first rotatable plate about a common pivot axis. 
     
     
         19 . The stroller of  claim 14 , further comprising a pivot anchor assembly comprising a first portion confronting a second portion and being spaced from the second portion along the pivot axis, the pivot member extending between the first portion of the pivot anchor assembly and the second portion of the pivot anchor assembly.
