A track-based swing ride system providing passengers a unique swinging ride experience. The ride system includes a ride track that supports a moving bogie coupled to the ride track that includes a drive assembly driving the bogie along a ride path defined by the ride track. The ride apparatus includes a pendulum arm pivotally coupled at a first end to the bogie, whereby the pendulum arm is suspended below the ride track and moves along the ride path with the bogie. The ride apparatus includes a passenger vehicle coupled to a second end of the pendulum arm opposite the first end of the pendulum arm. To provide the swinging sensation, the ride apparatus includes a roll driver rotating, concurrently with the drive assembly of the bogie, the pendulum arm about a roll axis extending through the first end of the pendulum arm.

Amusement device (1) comprising: a central shaft (2) comprising a base structure (2a); a plurality of arms (3a, 3b, 3c, 3d), coupled to said central shaft (2), each of said arms (3a-3d) being rotatable around a relevant arm axis (A2), provided with one or more vehicles (6) having seats for users of said amusement device (1); a gear system (7) for rotating said plurality of arms (3a-3d). The gear system (7) comprises a gear motor (M) coupled to a first gear (71), to rotate said first gear (71) and a plurality of second gears (72a, 72b, 72c, 72d), one for each arm (3a, 3b, 3c, 3d) of said plurality of arm, coupled to said first gear (71) so that rotation of the first gear (71) drives in rotation said second gears (72a-72d), the rotation of said second gears (72a-72d) causing rotation of each arm (3a-3d) around the relevant arm axis. The gear system (7) is configured so that the angular speed of said arms (3a-3d) is substantially identical for all the arms. The first gear (71) is directly meshing with said second gears (72a-72d), or it is coupled to said second gears (72a-72d) via one or more secondary gears.
