The invention provides a swing-type bicycle/tricycle. The swing-type bicycle/tricycle can swing leftwards and rightwards, and the gravity center of the swing-type bicycle/tricycle can be adjusted to keep balance and stability. A gyroscope capable of inducting deflection of a bicycle/tricycle body and a gravity sensor capable of inducting the magnitude of inertial force are installed on the bicycle/tricycle body. A motor and a swing rod which can rotate leftwards and rightwards according to signals of the gyroscope and signals of the gravity sensor are further installed. The swing rod drives the bicycle/tricycle body to swing leftwards and rightwards to keep the bicycle/tricycle body balanced and stable.

A saddle for peddle operated devices such as bicycles, tricycles, stationary bikes comprises a pair of rider supports sized to support the regions of the ischium and upper femur of the rider, each rider support being pivotally mounted to a normally horizontal mounting member (i.e., an “axel”) so as to provide a limited amount of free tilting movement about a common axis of rotation thus enabling unobstructed pedaling motion of the legs. The unique curvature of the rider supports allows the rider to maintain contact with the seat during a peddling cycle (rather than being thrown forward), maintain orientation of the rider's sit bones above the rider support axis of rotation during the peddling cycle and keep the rider's hips in balance during the peddling cycle.
