Patent ID: 8708866

Claim:
An exercise bike adaptable to perform a cardiac workout and abdominal workout simultaneously, the exercise bike comprising: a frame structure having a front portion, a middle portion, a rear portion and a base portion; a pair of pedals at the middle portion to enable pedaling of the exercise bike to perform cardiac workout; a resistance provider at the middle portion; a first sprocket at the middle portion connected to one of the pair of pedals and the resistance provider, the first sprocket rotates with the pedaling of the pair of pedals; a sprocket rotating means connected to the first sprocket and the one of the pair of pedals to rotate the first sprocket with the pedaling of the pair of pedals; a second sprocket at the front portion connected to the first sprocket through an engaging means, the second sprocket rotates with the first sprocket; an axis at the front portion and connected to the second sprocket, the axis being designed to rotate with the second sprocket; a cable connected to the axis to define a pulley system having a plurality of pulley wheels, the cable includes a first end and a second end; a seat mounted on a seat supporting structure at the rear portion, the seat includes a back rest and a pair of armrests; a seat adjusting means at the base portion to adjust the position of the seat; a monitor mounted on a monitor stand at the middle portion; a pair of legs at the base portion to support the exercise bike on a surface; an elastic band at the rear portion connected to the first end of the cable, the elastic band creates a tensional force thereon by getting stretched with the pedaling of the exercise bike; a plurality of connecting means for connecting the elastic band with the cable; a swing arm in the rear portion at a same level of height with the shoulders of a user seated on the seat, the swing arm being designed to connect with the elastic band through the plurality of pulley wheels in such a way that the elastic band swings along the swing arm; and a pair of shoulder straps connected to the elastic band and designed to insert along the shoulders of the user to stretch with the tensional force that pulls the user backward and allows the user to resist the backward movement by manually contracting abdominal muscles to perform the abdominal workout; whereby the pedaling of the exercise bike initiates the cardiac workout and the sprocket rotating means initiates the first sprocket to rotate and subsequently stretches the pair of shoulder straps generating the tensional force that pulls the user backward and allows the user to manually contract the abdominal muscles to perform the abdominal workout.
