The cycling apparatus includes a frame unit, upon which the pedal mechanism is mounted. The pedal mechanism is collapsible into the frame unit for easy storage. The frame unit supports a seat with adjustable back and arm supports whereby cycling exercise routines may be performed from a comfortable seated position. The back and arm supports may also be lowered to add to the collapsibility of the apparatus. ## Claims ### Claim 1 An adjustable cycling apparatus which comprises; a structural frame unit comprising a rigid frame, an adjustable seat mounted on said rigid frame, and an assembly support; and a pedal mechanism assembly unit having a pedal assembly and having an attachment means wherein said assembly unit is slidably and pivotally coupled to said assembly support of said structural frame unit such that the pedal assembly of said pedal mechanism assembly unit can be positioned at various horizontal, angled, and vertical levels, with at least a portion of said pedal mechanism assembly unit being positioned within said structural frame unit during normal operation of said apparatus; whereby said apparatus may be used to participate in defined lower body exercise cycling routines while in a seated position. ### Claim 2 (depends on 1) The adjustable cycling apparatus as claimed in claim 1, wherein said adjustable seat comprises; a horizontal seating means fixedly mounted on said rigid frame; a back support means adjustably mounted on said rigid frame such that the back support may be moved in either a forward or backward direction with respect to said horizontal seat; and an arm rest support means. ### Claim 3 (depends on 1) The adjustable cycling apparatus as claimed in claim 1, which further comprises at least two wheel assemblies attached on at least one end of said structural frame unit. ### Claim 4 (depends on 2) An adjustable cycling apparatus as claimed in claim 2, wherein said back support means further comprises two hingedly attached horizontal members thereby allowing said back support means to be hingedly moved between a substantially vertical position to a more horizontal position with respect to the horizontal seat. ### Claim 5 (depends on 1) An adjustable cycling apparatus as claimed in claim 1, wherein the pedal mechanism assembly unit comprises: an assembly structure; resistance means; wherein the pedal assembly comprises pedals connected to a hub; said hub and said resistance means are enclosed in the assembly structure; and said attachment means are on the exterior of the assembly structure; whereby a user rotating said pedals rotates said hub against resistance from said resistance means. ### Claim 6 (depends on 5) An adjustable cycling apparatus as claimed in claim 5 wherein the resistance means further comprises a flywheel, a friction belt, and a chain and sprocket system, such that said flywheel is connected to said hub of said pedal assembly through said chain and sprocket system, whereby a user turning said pedals rotates said flywheel against said friction belt through said chain and sprocket system. ### Claim 7 (depends on 6) An adjustable cycling apparatus as claimed in claim 6 further comprising an axle fixed to said assembly structure, said axle passing through the center of said flywheel and said assembly structure, wherein: said attachment means comprises two sleeve members, said sleeve members being pivotally attached to said assembly structure on said axle such that each sleeve member can be rotated, and said flywheel rotates around said axle. ### Claim 8 (depends on 7) An adjustable cycling apparatus as claimed in claim 7, wherein said assembly support of the structural frame unit comprises two substantially horizontal members and four substantially vertical members, wherein said horizontal members are fixedly joined at the forward and backward ends to said substantially vertical members and said horizontal members are sized to slidably fit within the hollow of said sleeve members of said attachment means of said pedal mechanism assembly unit. ### Claim 9 (depends on 1) An adjustable cycling apparatus as claimed in claim 1, wherein said apparatus is collapsible into a more compact configuration by lowering the overall height of said apparatus through said adjustable seat, and shortening the overall length of the apparatus by positioning said pedal mechanism assembly unit such that the majority of said pedal mechanism assembly unit is within said structural frame unit.
