Building the bike is done on site. The volunteers are very helpful, and will assist in selecting a good bike to start with (most are not "turnkey"). After you pick your bike, you then piece it together using parts from their extensive yard. The volunteers help, and you can then ride away a tuned and road-ready bike for less than a dinner out for two! Highly recommended!
You don't. You go to Free Cycles to build a bike.
