A bicycle training wheel bracket support for supporting the bracket at a desired height, comprising a brace member having a first portion apertured to accommodate the threaded end portion of a bicycle rear wheel axle, and a second portion comprising a torque arm having a forked extremity for embracing a bicycle frame, a housing secured between the first and second portions of the brace member, a substantially vertically extending sheath secured within the housing for receiving the training wheel bracket, said sheath having a transversely disposed aperture extending therethrough and situated for alignment with a selected one of the bracket apertures, a movable locking pin supported within the housing for substantially horizontal movement into the sheath aperture and a selected one of the bracket apertures, said locking pin being spring-biased into said apertures for locking the bracket at the desired height, and at least one projection rigidly secured to the locking pin and extending through an opening in the housing for manually moving the locking pin out of the bracket against the spring bias for permitting movement of the training wheel bracket within the sheath for alignment of another selected one of the bracket apertures with the sheath aperture. In the preferred embodiment a pair of substantially parallel retaining plates are affixed to the interior of the housing, and the locking pin is secured to a support bar which is situated between the retaining plates, with the support bar extending substantially parallel to the bicycle axis and having the locking pin extending transversely therefrom.
