The present invention describes a full-scale, immersive virtual reality (VR) bicycle simulator designed to provide users with a highly realistic biking experience. Leveraging standard bicycles mounted on stationary trainers, the simulator integrates advanced VR technologies to create a dynamic and interactive environment for biking within a VR world. According to the invention, there is provided a full-scale virtual reality (VR) cycling simulation system, including a stationary bicycle mounted on a training stand; one or more VR controllers attached to the bicycle; with the VR controllers configured to track at least steering and pedalling movements of the bicycle; and a processing unit configured to receive the orientation and rotation data from the one or more VR controllers and translate this data into corresponding movements within a VR environment.

A control system for a cycling trainer assembly, wherein the trainer assembly is configured to provide virtual shifting functionality, and wherein the trainer assembly is configured to be used with a partially deconstructed conventional bicycle. The control system includes an input for receiving a wireless control signal from a gear shifter component provided by the bicycle, and a component configured to process the control signal and in response trigger functionality that results in a virtual gear shifting operation by the cycling trainer assembly. In addition, a gear shifter component is configured to enable wireless gear shifting via a conventional bicycle. The gear shifter component includes embedded software that alternately configures the gear shifter configured to operate with a trainer device which provides a virtual shifting functionality.
