Ok I wrote and the guy - Tony Rentschler - got back straight away - very happy to hear we are liking his bike; a very nice man all round it seems.

He says he had it in mind to build a folder all along but wanted to get the geometry and handling right in this first one and that he might try a folder or demountable in another incarnation - which he might also upscale to 451 wheels for better handling. Probably not with a S&S coupling though. He says he spent no small amount of time looking at other folders - especially Moultons - and this is where the mono suspension comes from - something he's definately a convert to since building the MiniVelo.

The long steerer is aparently custom - two tubes simply brazed, and the rear spacing is the standard mtb 135mm for ease of sourcing parts which is pretty sensible if you ask me.

The bad news is - at least for now - he's only building for a hobby and as such isn't 'set up' as he put it for re-sale - though he says he will think this through and see if it's practicable. One problem is he's getting parts at full retail price rather than wholesale so things aren't really economic if say you wanted a frame with those dinky forks or whatever....

But maybe as a 'frame-only' deal he could be persuaded to knock out a few? I'm gonna ask - maybe he can find the time!
I'll keep people posted if they're still interested
