Didn't finish the bike or get a better picture but i did get the jack shaft done! The internal geared hub confused me a bit (anyone on here used one before?) but I think at least 1st gear will work. Sadly my muffler is in the way of the jack shaft so i'm going to have to bend it a bit.
The Y connector things for tying the brake levers together (regular bike parts) that the bike shop sold me don't make it around the tire! I'm either going to have to weld the brake holders farther forward or find some other way to make a Y connector for them.
