ABSTRACT:
A frame having a base and two horizontally spaced substantially upright elongate posts, a first of which carries a saddle seat. Mounted for rotation on the second post is a foot pedal spindle carrying first and second sprocket wheels. Also mounted for rotation on the second post is a disc spindle carrying a disc and a sprocket wheel. Mounted for rotation near the top of the second post is a hand crank spindle carrying a sprocket wheel. A drive chain is entrained over the disc sprocket wheel and the first foot pedal sprocket wheel. A second chain is entrained over the handle bar sprocket wheel and the second foot pedal sprocket wheel, which sprocket wheels are designed to provide predetermined different angular speeds to their respective spindles. A manually operable pointer is rotatably mounted on the second post to vary the spacing between two brake pads mounted on either side of the disc to provide a variable braking force to the disc corresponding to such spacing.
