A cushioning member (19) for articulated members (13, 13', 15 and 15') which resists hinging of the articulated members (13, 13', 15 and 15') together. In one form the cushioning member (19) is applied to trainer wheels (11 and 11') for a bicycle. The cushioning member (19) is compressed by first members (13 and 13') and second members (15 and 15') hinging towards each other. This allows the training wheels (11 and 11') to rise over obstacles such as bumps and the like so as to avoid inexperienced riders being tipped off the bicycle. typically, the cushioning member (19) is made from rubber or the like compressible material. The resistance force of the cushioning member (19) can be adjusted with a nut (51 and 51') and a bolt (47 and 47').
