It seems to me like they the same model. Are you saying they switched out the parts on a new bike?
Or do you mean the ones I saw might be a Chinese clone model like the 800+- Hummer bikes?
There are a few of those similar looking bikes. I have seen Montague Paratrooper and also the said Hummer. Hummer is a spin off from the original Montague. Montague became famous after the military ordered them for troop use. Both frames look alike but the replica ones, the joints will get loose and you will eventually lock it permanently with a strong nut and bolt

after a few hard uses.
Many of the frames are now made in China due to cost cutting and also cheap labour force as with many other products. In fact most products now. Even Taiwanese bicycles are now made in China and so are many bicycle components. Sometimes you see same products at much much different prices. Why?
It is all to do with warranty and quality control. A factory can run into over runs and they dispose off in bulk, hence cheap components. They do not carry warranty nor any responsibilty on these products. Like Shimano or SRAM, a few grades are made in China and they are very much cheaper but the principal do make higher grade components in other more higher quality factories to safe guard their brand. Cheaper ones which are their bread and butter needs to be competitive in the expanding market. They are not made to last, else everyone will become a 'ONE TIME CUSTOMER".
Also bulk purchase is also a contributing factor. A factory might order components in big quantity to make it standard fittings and usually they are very much cheaper than buying in nicely boxed form. Eg. a bottom bracket might cost you RM80 when yours is kaput and need to be changed but during the factory fitting, they might cost as little as RM20 or less. This is just figuratively off course, there's no way we will know the actual cost.
Just like Dahon, the frames are also made in China and factory over runs do get into traders hands and they labelled it other brands although they are from the same stock. They don't go through the same QC and many other processes though.
