DICK'S Sporting Goods will provide free in-store assembly service by a certified technician for any bicycle purchased in our stores or on our website (proof of purchase required). Please contact your local store to arrange assembly service. A bicycle is a complex piece of equipment that must be properly assembled and maintained in order to be ridden safely. We strongly recommend that you consult a professional bicycle mechanic to properly assemble, repair, and maintain the bicycle. If you choose to assemble the bicycle yourself, DICK'S Sporting Goods will not be held responsible for injuries or damages resulting from improper assembly.
