short clip of how suspension works

NOT TO SCALE, this is just the first animation to show my idea, some adjustment need to be made to get full travel out of the shock and to ensure chain tension is adequate.

 I agree that flex is a concern, but I don't think it's what he was initially trying to address. As part of a multi-step process, flex could be address after these questions are answered.

That said, flex could very well be an issue and rivet-team is right to be concerned. However, material selection and internal construction could make all the difference in the world.

A concern of mine would be lateral flex at the main swing arm pivot. Check out Mountain Cycles MC Dex and Soto Designs Turntable systems. I agree 100% with the need for stiffness in those areas I like how they've addressed it. The Mountain Cycle site has been flaky as of late, but you this pdf talks about it a little.

Lastly, I think the frame looks rockin! I dig the orange (I'm planning on repainting my Khyber Elite Orange and Black at years end). I'd love to see this as an AM or DH bike.

 this is very far from a production worthy design, all im trying to show is the concept and the functionality. Sure the swingarm could be bigger, without testing I cant be sure the best size, however i am sure this size could and would work. I think for a swingarm application smaller diameter tubing with thicker carbon would be better then thin tubing and wider diameter, also from this angle you cannot see that the carbon swingarm is actually one peice attaching to the other side at the top/front of the swingarm. I havnt put time into the swingarm attachment, many parts that I just simply cannot accuratly design without knowing the loads they are going to sustain, I am positive that the look of the frame could be made extremely strong with very little changes to the look.
