<p>A pedal exercise apparatus includes a main frame 10, a pedal unit 20 and two foot frames 40. The foot frames 40 are pivotally connected to the two ends of the main frame 10 at joints 45, and are selectively foldable relative to the main frame. The pedal unit 20 is pivotally connected to the main frame through a crank 21. Two ends of the crank 21 are pivotally connected with a pair of pedals 22. An adjustable resistance unit 35 may be provided on the crank to change the damping action of the crank as desired. When in use, the foot frames 40 are unfolded and placed on the ground for the user to tread the pedals of the pedal unit 20. The foot frames 40 are locked in the unfolded position by a spring biased locking pin 48. After use, the foot frames 40 can be folded for storage and transportation (see figure 6).</p> |
