I purchased this item five years ago and used it about four times a month. I am selling it because I bought a replacement. Below are the details and notes about the product: * The power and Bluetooth connection work without any problems. The resistance also changes during exercise. * The sprocket is not included. * The part that plugs into the outlet is damaged due to aging and has been partially reinforced with tape. It works normally after plugging it in. * The legs will be shipped attached. * One of the quick-release spring is missing. * The tire holder in the last photo is also included. * There are no instructions or original box. It will be shipped in a cardboard box with cushioning material. * There was an unusual noise at first when pedaling, but it became unnoticeable after pedaling for a while. I don't know the cause, but there were no problems with use. Please feel free to ask any questions in the comments.
