ABSTRACT:
A controlling device for a road condition display for an exercise bicycle comprises a picture device for providing a different motion picture of road conditions, a sensing device for sensing different road conditions and generating a train of corresponding pulses, an first counter for counting the number of these pulses, a frictional load device for generating various frictional resistances for the exercise bicycle, a pulse generator for generating at least one pulse when the frictional load device changes the frictional resistance, a second counter for counting the number of pulses from the pulse generator and records and updates the frictional load of the frictional load device, and a comparator for comparing the counted value of the first counter and the second counter and outputting a signal to trigger the frictional load device to update the load resistance according to the present motion picture.
