US Patent 9987514 Switchably swingable spinning bike

A switchably swingable spinning bike includes a bike body and a base. The base has a pivot portion and is pivotally connected to a swinging seat of a swinging device. The swinging seat has two buffers flanking the pivot portion. The swinging seat has a switching device that includes two undeformable propping members that flank the pivot portion. Each of the propping members is slidable with respect to the swinging seat until it props between the swinging seat and the base, thereby limiting the swinging seat's pivotal swing with respect to the base, and in turn switching the bike body from a swingable state to a non-swingable state.
