Abstract
A motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a retaining mechanism and a controller in communication with the motor. The retaining mechanism has a retaining member mounted at a rear end of the base under the endless belt and a sensor coupled to the retaining member. The sensor is configured to sense whether an object contacts the retaining member. The controller is configured to determine whether rotation of the endless belt is interfered by the object. When the sensor detects that the retaining member comes into contact with the object, the controller determines that the endless belt is interfered by the object and stops rotation of the motor to slow down or stop rotation of the endless belt.
