1. A collapsible scooter, comprising: a first portion comprising a bracket supporting a handle and a front wheel for rotation relative to said bracket about a steering axis, said bracket including an opening;a second portion supporting a rear wheel, wherein said first portion and said second portion are rotatably coupled by a pivot pin, said pivot pin restricting relative movement between said first and second portions to rotational movement about a fixed pivot axis and between a collapsed position and an operable position;an adjust pin supported by said first portion, said adjust pin extending through said opening in a direction substantially parallel to said pivot axis;a hook that extends at least partially around a circumference of said adjust pin in said collapsed position of said scooter; anda lever coupled to said hook, wherein said lever is configured to move said hook to permit said collapsible scooter to move from said collapsed position to said operable position;wherein said collapsible scooter further comprises a spring having a first end coupled to said adjust pin, said spring configured to normally bias said adjust pin in a direction tending to engage said pin with a recess. 2. The collapsible scooter of claim 1, wherein said second portion includes a slot, said adjust pin extending into said slot in a direction substantially parallel to said pivot axis. 3. The collapsible scooter of claim 1, wherein said bracket includes a second opening, said adjust pin extending through said second opening in a direction substantially parallel to said pivot axis. 4. The collapsible scooter of claim 1, wherein said adjust pin includes at least one cylindrical portion, and said longitudinal axis of said cylindrical portion is substantially parallel to said pivot axis. 5. The collapsible scooter of claim 4, wherein said cylindrical portion is positionable into engagement with said first and second recesses. 6. The collapsible scooter of claim 1, wherein rotational motion of said lever moves said hook radially from said pivot axis. 7. The collapsible scooter of claim 1, wherein said adjust pin defines a groove configured to accommodate said first end of said spring. 8. The collapsible scooter of claim 1, wherein said spring includes a second end that is coupled to said pivot pin. 9. The collapsible scooter of claim 8, wherein an outer surface of said pivot pin defines a groove configured to accommodate said second end of said spring. 10. The collapsible scooter of claim 2, wherein said second portion includes a second slot, said adjust pin extending into said second slot in a direction substantially parallel to said pivot axis. 11. The collapsible scooter of claim 2, wherein the slot is elongate and includes a first recess and a second recess, said adjust pin being positionable into engagement with said first recess to secure said collapsible scooter in said collapsed position, and said adjust pin being positionable into engagement with said second recess to secure said collapsible scooter in said operable position. 12. The collapsible scooter of claim 11, wherein said adjust pin moves in a radial direction relative to said pivot axis into engagement with said first and second recesses. 13. The collapsible scooter of claim 11, wherein said slot includes a first end and a second end, said first recess adjacent to the first end and said second recess adjacent to the second end. 14. The collapsible scooter of claim 11, wherein said first and second recesses extend from the slot towards the pivot axis.
