The invention relates to an amusement ride such as a roller coaster, more in particular to booster drives mounted on a track of such a ride. The booster drives each comprise at least one booster drive motor for driving booster wheels, for engaging a drive fin of a passenger vehicle to propel that vehicle along the track. According to the invention, the booster drive further comprises a base mounted to the track structure, a frame that supports the at least one booster drive motor and the two booster wheels, and a mobile carrier that connects the frame to the base via a left and a right carrier arm. These carrier arms are flexible arms and/or are pivotable connected to the base and/or the frame, such that in use they enable movement of the frame relative to the base. A biasing device resiliently forces the frame towards a predetermined position. |
