Abstract
Abstract There is disclosed a coupler for interconnecting two bicycles. The coupler includes a main support member having a vertical frame and eight telescoping crossbars, four on each side of the vertical frame, the ends of which can be attached to two side-byside bicycles. A seat, for carrying a child, for example, is provided on top of the central frame member. A toggle mechanism is also provided for attachment to the front wheel supports to insure that the front wheels turn together and are aligned at all times. The widths of the main support member and the toggle mechanism can be adjusted so that the separation between the two bicycle riders can be set as desired.
