An assembly for converting a three-wheeled baby stroller to a two-wheeled bicycle trailer configuration. The conversion assembly includes an upper frame attachment attached to the upper stroller frame. Left and right support members are connected to a forward portion of the upper frame attachment and extend downward and each have at a lower end thereof an axle extension assembly. This assembly is positioned between the end of the stroller rear axle and the stroller rear wheel to extend the rear wheel base of the stroller to provide increased stability. A tow arm assembly extends from a forward end of the upper frame attachment and at a forward end thereof carries a hitch which clamps to the seatpost of a bicycle. An elongated baseplate is positioned at the forward end of the stroller lower frame and securely clamped thereto. Left and right side suspension members are attached at an upper end to the tow-arm assembly and at a lower end to the baseplate and support the front end of the stroller frame when the front wheel thereof is removed. The baseplate further serves as a carrier for the removed front wheel. The base plate has a connector positioned forward of the stroller connectors which receive the lower ends of the stroller upper frame tubes. With the lower ends of the stroller upper frame tubes moved forward into the baseplate connector, the center of gravity of the stroller seat is moved forward and is lowered to provide increased stability. The left and right side suspension members also serve to transmit lifting forces produced on the rear wheels of the stroller to the seatpost of the bicycle so that the weight of the rider on the bicycle counters the lifting force to inhibit tipping and rolling.
