To be honest by Coyote Duel jump bike frame seems very well make, I think it must have been custom built tho got some nice parts on it. Also I like the look of the DH3 is it? too.
Sorry, the only other one I have at the mo is a (bad) closeup of the rear suspension.
It's a freaky frame. If you know how the Lawwill fork works (Frame stays put, wheel moves up and down) the rear end does the same. The rear is sprung on twin elastomers -one either side of the chainstays. It actually works quite well.
Other than that I know little about the frame. Maybe it is the only one.
I've just bought a slightly different crank so hopefully after finding some derailleurs I can take it for a test run
