I'm getting really kookie with this bike i'm building. I'll probably be machining my own gear box. I have an idea for an innovative clutch system, but it would be costly to make. If i can meld an already existing clutch into my design, then I'm ahead of the game. You can see in my VERY preliminary model that everything is quite tight.
The frame of the bike that is in the other picture will be swapped out for the new motorized frame.
