Smooth & Quiet: Equipped with an advanced belt-drive mechanism, the 6 kg heavy-duty flywheel effectively simulates cycling and provides you with a powerful full-body workout, while the spinning bike itself runs quietly. 2-in-1 Resistance Knob: Twist the resistance knob to adjust the intensity and make your workout more challenging and effective. Press the knob to stop the flywheel immediately. The textured adjustable pedals prevent your feet from slipping. Sturdy & Stable: This indoor cycle bike is made of a solid steel frame with a weight capacity of 150 kg. The support bar at the bottom gives the stationary exercise bike stability, and 4 anti-slip suckers prevent it shaking or rocking.
