Our stylish Dripex 2-in-1 treadmill has two modes to meet your different fitness needs. When the uprights unfold, the treadmill is set as “running mode” with a speed range from 1 km/h to 12km/h. You can jog or run at your desired speed to achieve your fitness goal. When the uprights fold down, it is set as “walking” mode and becomes an under-desk walking pad with a maximum speed of 4km/h. You can store it under a desk and walk while you work.
