That particular companies financial troubles had nothing at all to do with the bad press of their boss. Do you think that in 2009 when the "restructuring" began that it was some sort of cosmic time leak from today? Look at Volkswagen also, get involved in a world wide headline grabbing scandal, profits shoot up 15%.

Unless it effects the value of the product (or even if it does in VWs case) then consumers wont care. Really its only damaging to a company if their brand becomes really unfashionable but bike companies arent big enough to have that effect, nobody knows what a "dahon" is.

Personally would I buy another dahon?.. Nope. I would not buy any folding bike, too many non standard parts and I never use the folding ability anyway. But if you are looking for a folding bike and take the OP seriously, then what brands can you buy? I guess there are a few that seem backed by good companies and arent just made from junk off the Chinese shelf. Maybe just the Tyrell IVE, Birdy and a few other bespoke brands? But then you are going to have to do your homework on those brands, look into the history of each company, who runs them, where they source parts etc to be ale to tell if you are allowed to like their products or not...
