All bicycles sold at REI include a free warranty tune-up. New bikes go through a normal break-in period, after which readjustment is important for longevity and performance. Bring your new bike in to your local REI for its free tune-up within 20 hours of use or 6 months from purchase, whichever comes first. Contact your nearest REI bike shop to schedule this important service.


When you purchase your Diamondback bike on, have it shipped to any REI store where it will be ready for pick up fully assembled (and you'll avoid the home-delivery oversize shipping charge)!
