Abstract
Abstract Two identical mounting brackets are connected to the back axle of a bicycle, one on each side of the bicycle frame. Two complementary mounting bracket sockets are located at the top of the stand of an exerciser adaptor stand for a bicycle. The bicycle is connected to the stand by pivoting the mounting bracket sockets onto the mounting brackets, and disconnected from the stand by pivoting the mounting bracket sockets off of the mounting brackets. This mating arrangement of the mounting brackets and the sockets of the adaptor stand eliminates the need for a tool each time the stand is secured to the bicycle and disconnected from the bicycle.
