A scalable high-performance bouncing apparatus includes a carriage assembly that can support a person; a foot alternately retracting toward and extending away from the carriage assembly; and a thrust assembly having a tension force and effecting the retraction and extension using a plurality of engageable and disengagable elastomer tension elements that supply the tension force. A shield member integral with the carriage assembly protects the rider from accidental contact with moving parts of the thrust assembly, and an access feature enables engagement and disengagement of the tension elements for adjustment of the tension force. Piston pogo, scissor-lift pogo and scissor-lift bounceboard embodiments are disclosed.
