Tricycle with foldable double-wheel assembly

摘要

A tricycle with foldable double wheel assembly comprises: a frame, a single-wheel assembly and a double-wheel assembly respectively disposed at front end and rear end of the frame, and a handlebar assembly matching with the single-wheel assembly to control steering, the double-wheel assembly comprising a supporting beam and two wheels disposed on the supporting beam, wherein the supporting beam comprises two branches of same structures, the two wheels being respectively disposed on the two branches, the supporting beam having a first stable state where the two branches are open, and a second stable state where the two branches are put together side by side. The supporting beam in the double-wheel assembly of the present utility model is foldable so that it is not necessary to occupy a relatively large space to carry/store the tricycle and the usage convenience of the tricycle is thus improved.
