Abstract: The invention includes an exercise cycle having an upright frame and a spring assembly capable of permitting at least a portion of the upright frame to move or shift in a lateral side-to-side direction or a front-to-back direction. The exercise cycle includes a pair of front legs depending from a forward portion of the exercise cycle and a pair of rear legs depending from a rear portion of the exercise cycle. Each of the front legs and rear legs have a proximal section adjacent to the upright frame that is spaced a distance from a distal section by a spring.
