Biker Clubhouse was introduced on September 29, 2011 as the eighth non-cash generating property in New York / Manhattan. This is a limited-time-to-upgrade property in which you have 7 days to upgrade to level 10 (or as far as you can). After this period you will no longer be able to upgrade normally. You get to keep the level you reached and are able to build the items. However, you can still buy the required upgrade parts using Reward Points. Unlike regular crafting properties, there is no cost-per-item each time you craft. You can craft once every 18 hours.
