The tricycle according to claim 8, wherein the elongate post further includes a protruding collar for engaging the collar of the first connector for limiting the upward longitudinal movement of the elongate post relative to the collar of the first connector when the elongate post is in the in use position. 12. The wheeled vehicle according to claim 1, further comprising: at least one rear wheel strut with one or more wheels attached; wherein the at least one rear wheel strut has a rear strut connector mounting the at least one rear wheel strut to the seat to allow movement from a first in use position where the at least one rear wheel strut extends away from the seat to a second folded position where the at least one rear wheel strut extends adjacent and at least partially underneath the seat. 13. The wheeled vehicle according to claim 12, wherein the seat includes a central narrow portion; and wherein, when the at least one rear wheel strut is in the second folded position, the one or more wheels of the at least one rear wheel strut are disposed either side of the central narrow portion. 14. The wheeled vehicle according to claim 1, further comprising an elongate rod including: a first portion extending below the seat, the first portion of the elongate rod forming at least part of the front wheel strut; and a second portion extending above the seat, the second portion of the elongate rod forming at least part of the steering mechanism; wherein the front strut connector includes a collar capturing the elongate rod; and wherein the steering mechanism includes a handle at a top end of the elongate rod, the collar enabling rotation of the elongate rod about the elongate rod's longitudinal axis by turning of the handle to allow steering of the wheeled vehicle when the front wheel strut is in the first operative position. 15. The wheeled vehicle according to claim 14, wherein the elongate rod is captured in the collar to allow the elongate rod to longitudinally slide at least partially through the collar to reduce the protrusion of the handle beyond the seat when the front wheel strut is in the second storage position. 16.
