Follow along with our personal trainers as they lead your workout and help you get results. With iFIT’s Live Resistance Control technology, your trainer takes control of the resistance on your bike to realistically match the terrain of the workout. When your trainer goes up a hill, you’ll feel the burn. Experience a smooth, frictionless, and silent ride with our patented SMR™ Silent Magnetic Resistance, which allows you to adjust your training intensity without interrupting your workout or anyone around you. The TDF CBC comes equipped with 16 levels of digital resistance.
