There's a black Dahon Visc P18 in Kimbell Jaya. Difference though when you upgrade a Vigor is you will get the better Dalloy Vector frame but off course the price is about 1K higher than a Visc P18 after modding. When I had the Vigor (mine traded off already with a Dahon Dash P18), I followed the Vector P20 specs. I change the drive train to SRAM X5 just like the Vector P20 use. Effectively it becomes the Vector P20 which cost slightly over RM4000 locally.

Mine was, RM2000 for the bike, another RM800 for the SRAM X5 cassette, chain, X5 RD, X5 shifters and SRAM Apex FD. Add in another RM160 for the FD adapter and RD hanger. Total cost less than RM3000 plus also the old 9 speed components can be sold to offset a few hundred Ringgit. So, roughly about RM2600 for the Dahon Vector P20.

For the Boardwalk, apart from the parts mentioned before this, you have to change the whole crank and chainring as the original one on Boardwalk is fixed (cannot add another chainring).  Here's the picture of my wife's Boardwalk 

Gosh, that's really an economical soup up. You were saying that for roughly 1k you will get that setup? And the bike evenly match vector p20 gearing? 

Do you sell and install parts as well? Or any friend's shop you recommend most?

Ini racun nampak sedap.
How much total cost?

what are your thoughts on a foldable that has only 14-16" wheels? Are they as fast?

Interesting. I have been looking up on bikes and these 14-16" bikes seem lighter. So what I need to do is get one with good gears. Is that upgradeable?

flamingo huh... do they sell that in kL?

I can get the SRAM parts at the price mentioned. Yes, after modding it, it's the same specs as the Vector P20. 2 X 10 speed. If you go to V2, there's a picture of the Vigor modified there. When I traded the Vigor for the Dash, the whole groupset is taken out and it is now on the Dash (which is really not my choice as I wanted Shimano 105). If you are interested, I can transfer all the SRAM X5 to your bike, off course it will be cheaper larr.  since it is used but mileage is still very low or at the price mentioned, get a new set. I can arranged it from a friend's bike shop.
PM me if interested.

Here's the url for the Dahon Vector P20.
