This will be my 2nd build to be run in either the Amateur or Intermediate class but it will be my first single speed.
I started with an old Mongoose my son gave me for the project. I hacked off the top tube and built a perimeter top tube around the engine.
The thing was a little cramped for comfort so I added another bottom bracket to stretch the wheel base. I didn't have any tubing to replace the bottom tube with a longer one and lengthen the bike the right way and I wasn't gonna stub onto the old tube to lengthen it so adding the bottom bracket did the trick and made the wheel base 2 1/4" longer.
