What makes the manual treadmill manual?
The treadmill is manual because it has no motor. The belt is motored by the movement of your feet against the deck. As your movement stops, so does the treadmill belt. Most manual treadmills have an intelligent flywheel that increases the speed of the belt as you decrease or increase your speed. You don’t even need electricity for a manual treadmill as there is no plug in cables or motor.
