1.3 DEFINITIONS For the purposes of this Standard the definitions below apply.
1.3.1 Exercise cycle-a stationary device designed to be used for personal physical exercise by means of an activity simulating bicycle riding.
1.3.2 Flywheel-the wheel to which the energy of the cycling activity is finally directed, and to which a loading device for absorbing that energy can be applied.
2.1 GENERAL The guarding arrangements on exercise cycles shall be designed primarily to protect young children from injury when in the vicinity of a cycle which is either in use by another person, or stored in a location accessible to young children.
2.2 FLY WHEEL. DRIVE TRAIN AND LOADING MECHANISM Guards shall be provided to protect dangerous parts at all locations which constitute shear, crushing, or drawing-in hazards, giving particular attention to the following.
(a) The flywheel.
(b) The drive train.
(c) The flywheel loading mechanism.
Examples of these points of potential hazard are illustrated in Appendix A.
When tested in accordance with Appendix B, the exercise cycle shall be shown to have no locations where the specified test probes are able to penetrate a guard or otherwise be placed in a position where they are subject to any of the hazards specified above. Furthermore, there shall be no location where application of the specified axial force through the test probes causes any part of a guard to suffer permanent deformation (other than a minor dent no larger than the tip of the probe),or fracture of the guard or its supports.AS 4092 pdf download.
