So I finally collected enough balls to throw down the US$2,300 for a white/orange M6R + Schwalbe Marathons + EZ Wheels + C-bag. Like a proud new dad, I can't wait to gush about how cool the bike is, and how impressively small and portable it is even in a cramped city like Singapore.
I haven't ridden it over great distances, but I've done a fair bit of 'multi-terrain' transport with it - into fast-food restaurants, through malls, train stations, banks, onto trains and such. Especially in Singapore where space is at a MASSIVE premium and parking fees are mostly unavoidable except for residential side-roads, the bike is an absolute godsend.
The efficient island-wide network of trains and buses allows me to exercise and go everywhere, all the while enjoying sights I would never have noticed while driving.
I would not want to be dragging it downtown during rush hour, but at any other time the bike goes anywhere. I don't think there's many other folding bikes that can lay claim to that. My SS Dahon - one of the lightest Dahons besides the Curve - certainly can't.
Obviously, the downside is the constant paranoia of leaving it alone for even a minute. Thankfully I haven't had to use the bathroom while riding, as I'm not sure the minuscule stalls could accommodate even a tiny bike.
