the front triangle like structure 7 which functions to permit total range of motion and a front fork triangle 18 the rear triangle 14 a is important as a stabilizing block unlike conventional stationary exercise bicycles the small base of this triangle gives the bike its total rigidity in the rear the bottom bracket triangle 14 b gives the central part of the stationary exercise bicycle its rigidity and form for standing further arm or cross element 6 a allows for conventional pedal mechanisms i e crankarm and crankset to be used with a conventional clipless pedal or a regular bicycle pedal and toe clip the front triangle like structure 7 is wide enough to house a flywheel fig2 the front triangle like structure 7 gives the stationary exercise bicycle its total range of motion moving the flywheel in and out and giving the stationary exercise bicycle its base length or reel length from foot position to foot position the flywheel is connected to the frame 1 or 24 by the front fork triangle 18 further at least part of the front socket 4 rear socket 5 or seat socket 12 are formed with a hollow member having a cross section being non cylindrical the sockets described herein permit a matingly shaped connecting member such as the handlebar 8 the adjustable and detachable.
