Thanks for your words DoctorZ
Hope we can exchange ideas about bike design someday
I try to do the same U do but in Chile, with much less middles and resources, so, here is double or triple job: To get the materials, to find places where the industrial processes are available and to build it.
I hope someday my dream will become a bike enterprise in Europe or here in Chile

 Looks pretty cool, specially cuz I'm also working on a double chain design, this is really good cuz shows I'm not alone with this idea to all people that says I'm wasting time with 2 chains

 Nice one! Reminds me a Balfa BB7 but in heavy duty version

 nice
