The last price before the last increase was a 2 speed Brompton on offer as the last unit and it was sold for RM4200. After that, no 2 speeds or 3 speeds id popular, only the 6 speed is. So, if you are thinking of getting the lowest spec and modify later, the Sturmey Archer 3 speed hub gear is not cheap either but you do have the option of getting the 5 speed which converts it to 10 speed later though. Yes, Sturmeys are now Taiwanese and not British and they have came out with 5 speed of which the internals can be fitted into the 3 speed hub casing. The internals are available in UK. Here, nobody brings in let alone do it. But you can buy the whole 5 speed Sturmeys.

You can also try the 8 speed Sturmeys but I didn't read the literature about it so I can't comment but I do know they are available. So, there's pros and cons about getting the single and 2 speed lowest spec Bromtons. Just be warned though, since Bromptons are expensive, even though everything is basic simple stuffs, they charge premium because they know you can afford it. 

Just like Naza charges RM1600 without labour for Peugeot timing belt change while non-authorized specialist charges RM900 with labour or a RM500 rear wheel bearing and respectively only RM120 . Likewise with Peugeot or Bromptons for that matter , they threaten you with warranty default.  if you do it somehwere else.

that's the reason why i always cycle solo instead of joining group. I get much peace of mind riding myself.
Anyway i am pulling trigger on a brompton, but i don't know if i want to buy used at RM5k or new which cost RM1.5k more....headache.
