Abstract
Abstract An attachment for a bicycle having a wheel positioned rearwardly on the bicycle and a frame connecting the wheel to the rear axle of the bicycle for pivotal movement of the bicycle relative to the attachment. The attachment includes a fixture and an abutment means which limits the angular movement between the bicycle and the attachment when the forward end of the bicycle is reared upwardly. A seat and fender may be mounted on the attachment above the wheel and two closely spaced wheels may be used in place of a single wheel in the attachment.
