Magnetic Resistance Stationary Bike with speed, distance, calorie, time LCD display. Folds up for space saving when not in use. 8 levels of resistance easily changed with knob. Adjustable height with padded seat. I am 5'3" and it is a perfect size for me but would probably not be suitable for anyone over 6ft tall. Usually quiet but sometimes makes squeaking noise. If you know how to do a little maintenance, this could potentially resolve that. Size when not folded: 35"long x 18" wide x 47" height Size when folded: 19"long x 18" wide x 56" height
