US Patent 10039954 Spinning bike with swingable structure

A spinning bike with swingable structure includes a frame, a base member, and a limiting assembly. A mount of the limiting assembly is disposed on the frame, and two supporting bars of the limiting assembly are disposed at two sides of the mount and standing vertically. An adjustable member is adapted to adjust the two supporting bars to move downwardly until bottom ends of the supporting bars are in contact with the base member, so that the frame is not swingable with respect to the base member. Alternatively, the adjustable member adjusts the two supporting bars to move upwardly until the bottom ends are not in contact with the base member, so that the frame is swingable with respect to the base member.
