The oil tank is incorporated into the rear section of the frame, or what would be the swin
When looking at the bike the one thing that really stood out is the frame and its unique design: single-sided, rigid, drop-loop, with a suspended seat and the gas tank formed into the backbone. "I started off by using the Enginuity motor as my buck. First I made a loop for the bottom of the cases and then made my motor mounts. Then I put that hoop that the motor sits in into my frame fixture and built around it. I didn't have any specs, I just started holding metal up and scaling it with my eyes, thinking, a little more here, a little more there. It was cool that way because I didn't really know what my stretch would be. Then when I got the front wheel I made a stand to hold the wheel up and eyeballed it to see how far in front of the frame I wanted it placed. I kind of just pulled it all out of my ass."
One thing we noticed was how compact everything was on this bike-there is very little wasted space. "It's so tight, with the hidden motor mounts I made in the backbone, I had to install the gas tanks and cross over lines and stuff before the motor went in, which was a pain in the ass. The gas tanks were especially hard to get in because of the way I designed them to sit in the frame. It looks like the backbone is the only thing holding it in place," said Joe.
Lastly, we asked how he came up with the name God Sin. "I started thinking, 'I got this chance to win a million bucks, man it would be a Godsend to win that money. But then I thought you could go the other way 'cause it's a sin, because I'm sort of gambling and putting all my ideas into this one bike to win the money. So that's how I came up with God Sin."
Joe told us with all the starting and stopping he did on this bike (because it was supposed to be filmed as part of the build-off) the project took him about six months. Had he worked straight through he thinks he would have finished it in six weeks. The frame alone, however, took up quite a bit of time, Joe estimates about 100 hours of trial and error, eyeballing stuff, tacking pieces on, and hacking pieces off.
In the end all was not lost, even though the build-off was cancelled. Joe had the bike displayed in his new Martin Bros. boutique shop he recently opened in downtown Dallas, and several people saw the bike and immediately put deposits down for Joe to build them bikes based off the God Sin design. As for this particular bike, Joe has a very good customer who collects amazing bikes such as this, and he jumped at the chance to own this incredible one-off.
