摘要:
Multi-functional practice and training apparatus for use by skateboarders, skaters, bicyclists and the like. According to a preferred embodiment, the system comprises the combination of a board with a fulcrum member that are operative to assume at least three practice modes, namely: 1) a ramp mode whereby the fulcrum is placed at one end of the board and creates an upward slope for use in riding or jumping over objects; 2) a seesaw mode whereby the board is pivotally mounted upon the fulcrum and provides a platform surface upon which the user can rock back and forth while standing or riding thereon; and 3) a rigid rail structure whereby the fulcrum defines a rail for use in nullgrinding.null
