An attachment for the lower rear end of the forwardly and downwardly opening arcuate main frame portion of a tricycle to comprise a replacement for the rigid rear transverse axle assembly of a tricycle. The attachment includes a fork member similar to the front fork of a tricycle and includes a pair of generally parallel arms interconnected at one pair of corresponding ends by means of a transverse bight portion extending therebetween. The bight portion of the fork member includes a sleeve portion projecting from the side thereof remote from the other pair of ends of the arms of the fork between which a single rear wheel is journaled and the sleeve or sleeve portion projecting from the bight portion is telescopingly engageable with and rigidly securable to the rear lower portion of the main frame of the tricycle after the conventional solid transverse axle assembly of the tricycle has been removed. In this manner, the tricycle is converted into a low bicycle including driving pedals on its front steerable wheel. It is also envisioned that the attachment may have the fork member portion thereof constructed of two identical pieces with one half of the sleeve or sleeve portion of the fork member being defined on each piece whereby the halves of the sleeve member may be "through bolted" to the rear end of the main frame portion of the tricycle to be converted.
