摘要

A foldable tricycle, including a front wheel assembly; a mainframe, latched to the front wheel assembly via a front mount; a pair of rear-wheel assemblies; a pair of folding ring assemblies coupling the rear-wheel assemblies to the mainframe; and a mechanism for simultaneously unlocking the pair of ring assemblies and unlatching the mainframe from the front wheel assembly so that a single pulling motion on the mechanism unlocks and unlatches the foldable tricycle from an assembled state thereof so as to be converted to a folded state thereof
