All of our Bikes are brand new and come with a manufacturer's warranty. The frame and forks come with a Full 2-Year Warranty, and any defective parts on the bike come with a 120-day warranty. If a part is defective during the warranty period, just send it back to us; and we will send you a new replacement part. This warranty is expressly limited to the repair or replacement of a defective frame or defective part and is the sole remedy of the warranty. The good thing about these bikes is that the parts are interchangeable with parts at your local bike shop.
