NOTE: As with any complete bike, we recommend that you have a professional bicycle store build your bike. Bikes ordered through mail-order come partially assembled and need to be inspected and assembled by a bicycle mechanic. Failure to do so may void the manufacturer's warranty. Manufacturers’ warranties differ for every brand. You can check the brand's website for warranty information.
