If you own a newer Dahon, what's your experience with its reliability? My 2010 Mu P24 has been having many issues: missing weld (bike replaced); misapplied rim tape (rear) resulting in flats; shifting rod in the IGH had to be replaced (problems with shifting); loud creaking noises from the frame hinge (bike shop tightened the hinge, but not helpful much); handlepost hinge having a metal piece that broke off resulting in a strong handlepost wobble (in the bike shop for replacement now). All this since June of last year and 4000 km. I use it for commuting in Toronto. Are Dahons intended for an occasional recreational use only? Do 20"-wheel Bike Fridays have reliability issues, as well?
