CE - I respectfully disagree. I also feel it is obsolete when you can no longer get replacement parts or support. Even relatively current Dahons that is close to being the case. In a business sense that is obsolete to me as I can no longer waste any more time or money on an unsupported product. If they are phasing out that model it has become obsolete as it is no longer useful to them. I do not want to be in the business of making one-off custom parts just to keep my bike going.
