Top speed on this red treadmill reaches 12.8 mph, so the same deck covers a recovery walk and a hard interval session. A 3 HP peak motor runs quietly enough for apartment use, and the multi-layer non-slip belt covers 48.5 in by 16.7 in with shock absorption underneath. The HD screen reports time, speed, distance and calories, and two presets sit next to free speed adjustment. Bluetooth connects a phone for music through the built-in speaker. The steel frame measures 60.5-in W by 30.5-in D by 47.5-in H open and folds upright to 18.5 in deep, weighing 101.5 lbs with a 242.5-lb user rating. Set it up in a spare room or garage and fold it against a wall afterwards.
