A bicycle attachment comprises a pair of spaced rotatable wheels for engaging with a support surface, a connecting portion extending between and secured to the wheels, and a securing portion hinged relative to the connecting portion such that the securing portion is able to pivot relative to the connecting portion. The securing portion is adapted to be secured relative to a fork of a bicycle such that swiveling the fork relative to a frame of the bicycle also swivels the wheels and the connecting portion relative to the frame, and such that pivoting the securing portion relative to the connecting portion also pivots the fork relative to the connecting portion.
