ABSTRACT:
An attachment for a two wheeled bicycle allowing a mentor to provide a graduated correcting and stabilizing force to the bicycle for aiding a novice rider to maintain balance and gain confidence. The attachment comprises two substantially parallel rigid tubular members having an inside diameter being fastened to a bicycle frame and a hairpin shaped handle having a resilient connection to the members. The hairpin includes a U-shaped portion having extended straight parallel limbs. The end of each straight limb is connected to a spring-like bendable element which is inserted partly or fully into the tubular members. The spring-like elements have a sliding interference fit within the interior of the tubular members. The U-shaped handle allows gripping by the mentor who adjusts the degree of correcting and stabilizing force provided by the attachment by moving the spring-like bendable elements further into the tubular members, thereby reducing the available flexing length for greater stabilizing force or by partially withdrawing the spring-like bendable elements from the tubular members, thereby increasing the available flexing length, for reduced stabilizing force. A locking device is provided to retain the straight sections of the U-shaped handle when fully inserted into the tubular members.
