Wonder Cycle, the home fitness system provides a low-impact, full-body workout with two seat positions for upright or recumbent cycling. The bicycle delivers a heart-pumping cardio workout that works the legs and core, while the built-in bands’ three resistance levels tone muscles in the shoulders and arms. A digital display shows speed, heart rate, calories burned, and elapsed time. Unlike many indoor bikes, the padded seat includes a backrest for support and stability, and the system’s rubberized base prevents it from rocking while in use. The bike’s adjustable magnetic resistance system requires no electricity, so it can be set up anywhere. After a workout, it collapses to 18-inch W and rolls on two wheels to conveniently stow in a closet. Sturdy steel frame supports up to 350 lbs.
