Any bike like your looking for if it's out there is going to cost a few thousand dollars. Ritchey makes the Breakaway, a bike I've read good things about but again your looking at a few thousand dollars new. What I not sure of is why you are dismissing folding bikes from your choice. The reason I never bought a Moulton is that it doesn't fold and doesn't ride much better than a Brompton. You may need to rethink your plans to meet your budget. There are really good folding bikes out there at price points that are consumer friendly. Everyone here owns one or more folding bikes and can tell you that given the nature of the smaller wheels for the most part ride really well.
