ABSTRACT:
An exercise bicycle has a suspended wheel which is sleeved rotatably on a wheel axle. The wheel axle has a first key-way formed in one end portion thereof, and two opposed second key-ways formed in two opposite sides of the other end portion of the wheel axle. One of the second key-ways and the first key-way are aligned with each other and formed in the same side of the wheel axle. Two swing arms are secured to respective end portions of the wheel axle. One of the swing arms has a first key engaged with the first key-way and the other swing arm has a second key which is selectively engaged with one of the second key-ways so that the first and second keys may be connected to the same side or opposite sides of the wheel axle. Two swing levers are mounted pivotally at their lower ends on a base frame and connected at their upper portions to the respective swing arms. When the swing levers are swung by hand in either the same direction or opposite directions, the wheel can be rotated through a transmission line.
