A steering lock, and a method of use, for connecting child's bicycle (2) behind adult bicycle (4), with the front wheel (6) of child's bicycle (2) being elevated so that the adult rider retains steering control. The steering lock comprises receiver (20) or pivot receiver (30) attached to the head tube (13) of child's bicycle (2), a coupler (22) attached to a bicycle tow bar (24) on adult bicycle (4), and a steering lock pin (10). As coupler (22) is secured against receiver member (20) or pivot receiver (30) with quick-release safety pin (25), steering lock pin (10) is forced through aligned holes in head tube (13), steering fork tube (15), and handlebar stem tube (17) on child's bicycle (2) to lock one to the other during tandem travel. Thus, child's bicycle (2) can be expediently converted from independent operation to a tandem configuration multiple times during the same ride.
