Abstract
A method for producing a bicycle saddle includes the steps of: (a) forming a rigid saddle base having therein a hole; (b) positioning the saddle base on a projecting mold part of a male mold, wherein the projecting mold part has a surface contoured to complement a concave inner surface of the saddle base, and the surface is formed with an indentation; (c) placing a foam material in a female mold; (d) causing the projecting mold part to project into and close a mold cavity of the female mold; and (e) forming a saddle cushion around the saddle base by causing the foam material to expand and fill a space around the projecting mold part and then fill the indentation in the projecting mold part through the hole in the saddle base.
