*Giant & Liv Bicycles are available for purchase online, but due to warranty regulations, must be shipped to qualified Giant dealers, as bicycles must be assembled by a qualified bike mechanic in an approved store - This is an international policy and usually will require an additional fee to build the bike. This will be confirmed by one of our online staff after purchase of the bike.
