This little stationary bike is small, yet very durable. The box came swiftly and arrived in good shape. My adult son got on it and pedaled away and it held up nicely to him, yet my small frail little body fits it perfectly as well. I set it up all by myself in about 1 1/2 hours and many of the bolts were already in place making it easy to attach the seat, back, handlebars, and other moving parts. The instructions were easy to follow. The seat is sturdy, unlike the seat in my old stationary bike which was broken by my 200lb. mother just sitting on it. This one is much studier with a back rest and hand rests that are well worth the extra expense. It is very attractive and very quiet to ride, and the electronic panel that bolts onto the handlebars has a small holder that holds my book that I read each morning or a cell phone so that you can multitask. I am going to be unable to use my elliptical due to a surgery, so this little bike is perfect for cardiovascular workout, and it does get my heartrate up enough that my Fitbit can pick up on for a moderate workout. It also has a pulse receiver so you can use the bike to take your pulse as you ride. I have already been on it over 3 hours and have not even had it a week!
