Abstract: A clamp has an inner end wall and a pair of opposing arms which form a U-shaped structure thereby providing a U-shaped opening in the clamp. This U-shaped structure matingly engages one end wall and the side walls of a rectangular sleeve member which is fixedly attached to the frame of a bicycle exerciser. A rectangular seat post is telescopically fitted within the sleeve member for vertical slidable adjustment relative thereto. Fixedly attached to and protruding from a recessed portion of the inner end wall of the clamp into the U-shaped opening is a pin member. Mating apertures are formed in the the end wall of the sleeve member and an end wall of the seat post through which the pin member fits. The clamp is held in position in engagement with the sleeve member by means of a spring connected between the ends of the arms thereof and the frame of the bicycle exerciser. A series of similar spaced apertures are formed along the longitudinal extent of the end wall of the seat post.

Abstract: Handlebars for a stationary exercise bicycle are mounted on the front post or main body of the bicycle for pivotal adjustment and fixed positioning in a selected pivotal position relative thereto. Such handlebars have a central bar member which is connected to the post and a first larger handlebar section and a second smaller handlebar section which sections are positioned on opposite sides of the central bar member. The first larger handlebar section is in the form of a loop, the ends of which are attached to the ends of the central bar member, this larger handlebar section having a recessed portion positioned directly opposite the central bar member. The second smaller handlebar section is also in the form of a loop the ends of which are attached to the ends of the central bar member and the ends of the larger section. The smaller handlebar section has two substantially straight sides which are interconnected by a third side which is positioned directly opposite the central bar member.
