Step 9: Adjust Height of Bottom Bracket.
Once the forks are solidly welded, place them into the frame to have a look at what you have so far. Most likely, the bike will seem to lean back too far, and the bottom bracket will be very high. Because of the extreme fork length, the frame has been pulled backwards creating the "skyscraper" style chopper. Although the bike would be ridable in this configuration, and it may indeed suit your style, I decided to lower the bottom bracket a few inches by making a small mod to the frame. Since I planned to remove the top tube and convert the frame from a girl's frame, this wasn't a big deal.
