ABSTRACT:
A training wheel assembly for a bicycle including brackets for attachment to the body of the bicycle and a pair of auxiliary wheels supported by the brackets for engagement of the ground distally of and to opposite sides of the bicycle utilizes a link member connected between each auxiliary wheel and a corresponding bracket and cables operatively attached between the front wheel of the bicycle and the link member. Each auxiliary wheel is journaled at its center to a link member for rotation relative thereto, and each link member is connected to the corresponding bracket for pivotal movement relative thereto so that when the brackets are operatively attached to the bicycle body, the center of the auxiliary wheels are pivotally movable relative to and about the bracket between a raised condition and a lowered condition. The cables are connected between the front wheel of the bicycle and the link members for pivoting the auxiliary wheels between the raised and lowered conditions in response to a steering turn of the front wheel to either accommodate or contribute to the leaning of the bicycle when turned to effect a steering change so that the normal action of a bicycle is simulated and the bicycle is stably supported by the training wheel assembly during the course of the steering change.
