This exercise bicycle is wonderful for limited space in your home, easy to assemble, with easy-to-follow instructions. The tension settings are for any beginner to achieve a workout with minimum pressure on the knees and hips! The pulley weights work for an alternator variation, creating a dual effect. It has 3 adjustable positions to accommodate comfort, and the backrest is an added plus. I would highly recommend this bike for anyone 60 and over to help maintain their strength during those long, cold winter days spent inside.
