STURDY STEEL FRAME FOR LASTING STABILITYOur recumbent exercise bike is constructed with a commercial-grade steel frame, supporting up to 400 pounds. Unlike flimsier models, the reinforced base and wide footprint ensure a rock-solid, wobble-free ride even during intense workouts, providing confidence for all users. CUSTOMIZED COMFORT WITH EFFORTLESS ADJUSTMENTSExperience personalized ergonomics. The plush seat offers smooth, continuous forward/backward sliding (not just preset holes), while the backrest features 5-position height adjustment. The innovative lever-controlled sliding seat adjustment makes finding your perfect fit quick and simple, unlike inconvenient knob-based systems.
