The small is easy but the light is a bit hard.    Although most are in the range of 13 kgs, it is the bulkiness that makes carrying it bothersome. The Bromptons , although 14+ kgs, their fold design and also the handling of the folded bike makes the carrying easy. It's hard to actually find the center of gravity of the folded bike in most folding bikes. Some are folded too thickly and this is where Dahon wins, their folded thickness is less than many. It's because the handlebars folds in the center. Even Terns seems bulkier because of the placement of the handle bars on the outside.

So, in you query, Get the Brompton if you are willing to fork out 7K or get the China copy version of it for about 2K. If you don't really need lots of gears, the Dahon EEzz is good, or the Dahon Dove or similar (single speed 14 inch wheels).

Thank you so much for your replies and input etigge,KenC,weikee & mizi28
Appreciate it very much.

Yeah, it was a pretty vague question indeed and I do apologise for that.
I took all the advice and suggestions from all of you and did my own research as well.
It seems to me that 16" aluminium will be the best bet for daily MRT commuting in terms of portability.

I'll fork out a bit more and will be getting the XDS FA16 7sp for myself and Oscar Vogue 16" for my fiancé.
Would love for her to get into biking as well during the weekends.
Still waiting on the stock availability from SL Dengkil and will post up pics when they're here.

Thanks guys!

carry to MRT is one thing, but the distance thereafter from MRT is another issue.
Say you got 14" and after each mrt ride u are cycling 3-5km it is quite ok.
Say after MRT you got another 20km to 30km, that's a different story..however it is doable on a 16"..14" might takes a bit more time.

Having said so, it is always a trade off between size, speed and comfort.
for me i think i can sustain 30km on a 16inch and it may be slower than 20". that's a trade off i am willing to have as i am carrying it overseas for city sightseeing.
however I am doing long distance touring too i.e 90km to 120km per day across cities, in this scenario i would like to have at least a 20" to ride on.

Have u check the distance yet? i used to commute daily with lrt and i was using a Dahon eezz D3. 3 speeds and i enlarge my chainring to 42T (that's the maximum). 5km from lrt to home and 3 km from lrt to office. If i ride straight that will be 25-30km depends which route i take.

Will be better if you have your budget in mind. To be honest i think the eezz D3 is the perfect balance on price/size/practical to commute.
-Less than 3K,
-fold almost same size as brompton,
-can be roll along easily (Not as easy as brompton),
-9KG (mine was lighter, change to carbon handlebar,carbon seatpost, and lighter crankset) Around 9kg with all accessories,
-3 Speeds and not to forget the super fast unfold process.

Enough for most of the hills. I even climb Datuk Bandar hiil and genting sempah with this bike before. slowly but surely.

After half a year i commute with lrt, i ride straight to office instead because that took lesser time. Sweat more but it's my own office so i shower inside, problem solved, and then i let it go as i don need a folding bike anymore. Mainly commute with my RB now.

If you dont mind to fork out 3K for a bicycle, go for Dahon eezz D3. Strongly recommend for commuting.

With a bike i think u might as well go with Bike-Mrt-Bike option. The LRT is not very friendly with bike during rush hour. In fact it's not allow. I use a bag and went in, no issue. But because it's much more pack than MRT, to get in and out might be frustrated as most people will stand near to the door.
Mrt is fine. More spacious and less passengers.
