The FitTransformer Pivot is an industry-first modular fitness architecture that separates the intelligent drive system from the physical frame. At its core is the CoreModule™, a universal, detachable smart motor. Docking the CoreModule™ into a shared chassis and swapping interchangeable structural modules — such as quick-release seats and exoskeleton linkages — reconfigures a single, compact station into an upright bike, a recumbent bike, or an elliptical trainer. This approach removes the need to purchase three separate machines, reducing home space requirements and hardware redundancy. The system supports three training modes: high-intensity cycling for cardio conditioning, back-supported recumbent riding for rehabilitation, and low-impact elliptical strides for joint-friendly training. The CoreModule™ identifies which structural module is attached, adjusts resistance automatically, and outputs simulated terrain feedback to the companion App, enabling smart home automation and health-data syncing. It is designed to be shared across future strength and rowing equipment in the FitTransformer line.
