The concept for Build or Bust was that host and custom motorcycle builder Russell Mitchell took in a member of the public who thought it would be easy to build a bike "just like the guys on TV". Russell gave the guy (or girl) access to all the tools and parts necessary to make a custom motorcycle, allowing the contestant one month to assemble it. If at the end of that time the contestant built a bike that met Russell's standards, they get to keep it. If they didn't, they lost the motorcycle.
