1. A folding assembly for use with a foldable stroller comprising: a first pivot member comprising a first notch;a second pivot member comprising a second notch;a mounting member, wherein the first pivot member, second pivot member, and mounting member each include a through-aperture defining an axis of rotation about which the first pivot member and second pivot member rotate about with respect to the mounting member, the mounting member further comprising: a pivot end;a support end; anda locking mechanism configured to engage with the first notch and the second notch in a direction orthogonal to the axis of rotation when the first notch aligns with the second notch to selectively lock the first pivot member, second pivot member, and mounting member in a fixed position, preventing rotation there between; anda support member; wherein the first pivot member and the second pivot member are rotatably mounted to the pivot end of the mounting member. 2. The folding assembly of claim 1, wherein the mounting member comprises a tubular body defining a cavity and a longitudinal axis in the mounting member extending between the pivot end and the support end of the mounting member. 3. The folding assembly of claim 2, wherein the mounting member has a circular cross-section. 4. The folding assembly of claim 2, wherein the mounting member and the support member are aligned coaxially about the longitudinal axis of the mounting member. 5. The folding assembly of claim 2, wherein at least a portion of the support member extends into the cavity of the mounting member. 6. The folding assembly of claim 2, wherein the locking mechanism comprises: a locking head slidably mounted within the cavity of the mounting member; anda spring captured between the locking head and the support member, wherein the spring biases the locking head towards the pivot end and the first and second pivot members. 7. The folding assembly of claim 6, wherein the locking mechanism further comprises a lever pivotally mounted to the mounting member at a pivot point. 8. The folding assembly of claim 7, wherein the mounting member comprises a slot, extending along at least a portion of the outer surface of the mounting member, parallel to a longitudinal axis of the mounting member, through which the lever passes. 9. The folding assembly of claim 8, wherein the lever comprises a first lever end extending through the slot into the mounting member from the pivot point to the locking head and a second lever end extending from the pivot point outward from the mounting member. 10. A folding assembly for a foldable stroller comprising: a first rotatable member;a second rotatable member;a rear wheel support;wherein the first rotatable member and second rotatable member each comprise; a disk;a co-planar elongated arm extending outward from the disk; andan arcuate perimeter around the disk with a notch therein,wherein the first rotatable member and the second rotatable member are mounted to and rotatable with respect to the rear wheel support;a locking mechanism slidably mounted to the rear wheel support and biased towards engaging the notches in the first rotatable member and the second rotatable member to selectively lock the first rotatable member and the second rotatable member with respect to the rear wheel support; anda lever, pivotally mounted to the rear wheel support, and operably coupled to the locking mechanism. 11. The folding assembly of claim 10, wherein the lever is configured to retract the locking mechanism from the notches in the first rotatable member and the second rotatable member to allow for a rotation of the first rotatable member and second rotatable member with respect to the rear wheel support. 12. The folding assembly of claim 10, wherein each of the notches of the first rotatable member and the second rotatable member comprise: a first radial surface extending radially inward from the arcuate perimeter;a second radial surface extending radially inward from the arcuate perimeter; anda bottom surface extending between the first radial surface and the second radial surface. 13. The folding assembly of claim 10, wherein the locking mechanism further comprises a distal end comprising a distal end profile configured for selective engagement with each of the notches of the first rotatable member and the second rotatable member. 14. The folding assembly of claim 10, wherein the first rotatable member disk, the second rotatable member disk, and the rear wheel support each comprise an aperture therethrough, defining a common axis of rotation. 15. The folding assembly of claim 10, further comprising a pivot member passing through the aperture of the first rotatable member disk, the second rotatable disk, and the rear wheel support, the pivot member allowing the first rotatable member and the second rotatable member to pivot thereon and configured to maintain the alignment of the first rotatable member, the second rotatable member, and the rear wheel support thereon. 16. A foldable baby stroller comprising: a front wheel fixed to a left front wheel frame and a right front wheel frame;a left rear wheel fixed to a left rear wheel frame;a right rear wheel fixed to a right rear wheel frame;a left handle frame;a right handle frame; anda first locking folding assembly;wherein the first locking folding assembly comprises: a first rotatable member pivotally mounted to a support member about a pivot axis and fixed to one of the left front wheel frame or the right front wheel frame;a second rotatable member pivotally mounted to the support member about the pivot axis and fixed to one of the left handle frame or the right handle frame;a locking member slidably mounted to the support member, and slidable along an axis parallel to a longitudinal axis of the support member;wherein the support member is fixed to one of the left rear wheel frame or the right rear wheel frame;wherein the first rotatable member and the second rotatable member each comprise an arcuate perimeter comprising a notch;wherein the locking member is adapted to engage the notches in each of the first and the second rotatable members, to selectively lock the rotatable members from rotating with respect to the support member and lock the stroller in an unfolded state. 17. The foldable baby stroller of claim 16, wherein the first locking folding assembly further comprises a lever operably coupled to the locking member for the selective retraction of the locking member away from the notches in each of the first rotatable member and the second rotatable member to allow for a rotation of the first folding assembly to adjust the stroller between a folded state and an unfolded state. 18. The foldable baby stroller of claim 17, wherein the lever is pivotally mounted to the support member. 19. The foldable baby stroller of claim 16, wherein the first locking folding assembly further comprises a compression spring configured to bias the locking member toward the first and the second rotatable members.
