Much of the emphasis in objectives discussed thus far relate to commuting folders. There will be distinctly different objectives for a travelling touring folder.
A travelling folder needn't break down quickly, but there is more emphasis on compactness to fit in airline dimensions. It needs be a better performing bike as it will be the high end bike at the distant location. Depending on terrain, there may be a need for suspensioin-somethimes the suspension can be incorporated as part of the folding.
There is also a significant need for folder improvements in the recumbent area.
More thoughts for the commuting type folders-grease free features such as a full encircle chainguard or belt drive.
