A motorized treadmill that provides more fluid rotational motion of the treadmill belt, increases the life of the motor, provides more stable and reliable elevation of the treadmill, and provides automatic dampening for users of all weight ranges. The treadmill includes an external frame having first and second longitudinal side rails and at least one frame cross-bar extending therebetween, and an upright frame section that extends upwardly from a first end of the longitudinal side rails. First and second rollers are rotatably mounted on the external frame and positioned so as to be substantially perpendicular to the longitudinal side rails. The first roller is coincident with a first axis. A deck is mounted on the external frame and positioned between the first and second rollers and the longitudinal side rails. An endless belt is mounted around and extends between the first and second rollers for rotation therewith. A motor assembly including a motor, and a motor shaft that is coincident with a second axis and is rotatably driven by the motor, is rotatably coupled to the first roller for rotatably driving the first roller. The treadmill also includes a flywheel assembly that is mounted on the external frame and includes a flywheel fixedly mounted on a flywheel shaft that is coincident with a third axis. The flywheel assembly is coupled to and rotatably driven by the motor assembly.
