An exercise bicycle includes an elongated base frame, two support frames mounted on the front portion of the base frame and an adjustable seat mounted on the rear portion of the base frame. A driving assembly, a hand operated assembly, a transmission assembly and a load applying assembly are mounted to the support frames in a compact manner. The driving assembly has a first wheel and a second wheel rotated with the first wheel. The hand operated assembly has a third wheel with a peripheral groove mounted to the second shaft, a rope member wound around the third wheel in the peripheral groove. The transmission assembly has a fourth wheel and a fifth wheel rotated with the fourth wheel. The load applying assembly has a sixth wheel and a seventh wheel rotated with the sixth wheel. A damping fan is coaxially connected to the seventh wheel. When the user pedals and thus rotates the first wheel in a predetermined direction, the second, fourth, fifth, sixth, and seventh wheels and the damping fan are in turn rotated in the predetermined direction; and when the rope member is pulled toward the seat by the user, the third, forth, fifth, sixth, and seventh wheels and the damping fan are in turn rotated in the predetermined direction.
