ABSTRACT:
An exercise cycle having dual resistance structure as disclosed. An exercise cycle utilizing a pedal and crank and sprocket to drive a chain to a front mounted plastic wheel which employs a plurality of blades to form a fan to provide air resistance when the wheel is rotated. Additionally, the hub of the wheel is contacted with a strap to cover a significant portion of the circumference of the wheel whereby the strap may be tightened to increase the frictional resistance between the strap and the hub of the wheel to provide additional resistance when the front wheel is rotated by means of an exerciser pedaling the exercise cycle. A heat dissipation band covers the circumference of the wheel to dissipate heat due to the frictional resistance of the strap.
