Arm lever for an exercise bicycle
 An arm lever for an exercise bicycle has a pivot portion to be mounted pivotally on a front end portion of a bicycle frame and a bottom end to be connected to an end of a crank arm. The bottom end of the arm lever is provided with a locking plate which has a forked extension with a distal bottom end, an upright slit that opens from the distal bottom end, and a plurality of spaced locking holes that extend through the slit. The slit permits the extension of the end of the crank arm therein. The forked extension is connected to the crank arm at a selected one of the locking holes to vary the distance of the end of the crank arm from the pivot portion and vary correspondingly the range of pivoting movement of the arm lever to suit the user's physique.
