so much more useable than a large stationary bike. very suitable for seniors wanting to get a bit of extra exercise while watching TV, reading or just sitting ( it folds away , and sits beside our couch when not in use , and is easily in reach for when we want it ). Its extremely quiet and wont bother the others in the room with you ! its not for athletes missing the gym, its for people trying to supplement a little exercise into their day to stay healthier without having to go somewhere else to do it, its great for wintery days when you are trapped in the house !
