Semantic Business Analytics in Industrial Facilities - a Case Study.

A bicycle frame with asymmetric chain stays. The rear caliper brake is mounted across the underside of the chain stay tubes. The chain stay tubes are asymmetric. The front portion of the chain stay tube on the left side, opposite the chain, is curved farther outwardly from the centerline of the frame than the corresponding front portion of the other chain stay tube to provide a first step completely covering the end of the brake actuating arm to provide a support for a performer's foot while protecting the brake actuating arm from foot pressure. Second, third, fourth, and fifth foot-supporting steps or standing platforms are provided respectively by an upwardly-arched tube secured across the seat stay tubes, outwardly-curved rear portions of the chain stay tubes extending past the rear axle, and a diagonal tube secured between the down and seat tubes.
