[Class 132 (i)] A structure for acrobats comprises a pyramid shape support A having mounted thereon a circular track a and a member B which can oscillate and rotate about its centre and carries trapezes e or similar gymnastic devices and a motor bicycle b. Normally the bicycle runs on the track a and rotates the member B. If, however, the acrobats move to one end of member B the latter rocks and raises the bicycle into the air.
