I don't think that would work. It would be better to run the hose externally so that it can make a big loop when folded. That's what I did on my Dahon Jetstream.What's the experience like with hydraulics on a folding bike? I have to route through the frame a through the hinge and slinky. The slinky should prevent kinking, but are the hoses going to be happy folding like that?
