Performance

Nautilus T618 performance

This machine is best for walking, jogging or light running in this price range. Its running area is slightly smaller than other folding treadmills but it still offers 60″ length which is minimum for anyone with a long stride.

Incline

This T618 treadmill comes with an automatic incline range between 0% to 15%, perfect for high-intensity interval workouts. However, the deck can only be adjusted if the machine is connected to a power circuit.

You can adjust the incline from the control unit or from the keys situated into the left handlebar.

Step-Up Height

Its running platform is placed at approx 9″ above floor level. The space remaining between the deck and the floor is approx 4.5″. To avoid any ceiling height problems makes sure that the ceiling in the room where you’ll be using the machine is at least 15″ taller than your own height.
