Treadmill and exercise bike for sale. Location Dhahran Al Janub. I just bought it a week ago from Attar Al Hikmah, and its invoice is available with the date, and its accessories are available. The reason for selling is that I bought it and wanted to use it, but my house is small and I couldn't find a place for it that would provide privacy for use. The selling price for the treadmill is 900. The exercise bike is 350.
