Cardio machines for home gyms, studios and commercial gyms. The Endurance R300 air rower is our best-selling machine: true air resistance, a commercial steel frame and Bluetooth tracking. The Endurance FB300B air bike works your arms and legs together for HIIT, and our indoor cycling bikes run from the home Best Fitness BFSB5B to the heavy-duty Endurance ESB250 PRO. Every one ships free Australia-wide from our Adelaide warehouse.
