Since when did having your bikes stolen become an issue of national interest? If your extremely cheap bikes are getting persistently stolen, that tells me that you aren’t locking them well enough. Suppose you use a solid U-lock where almost everyone else at the same location uses cable locks. Unless your bike is significantly more expensive-looking than theirs, thiefs would not target your bike before theirs. Since, in my observation, almost every bike parked at MRT stations is locked with cable locks, I conclude that to get so many bikes stolen, you must be locking them quite badly (with lower security than your average bike-MRT commuter).
I pretty much regard locking your bike with a cable lock as the equivalent of leaving cash on a public bench. No one would think of writing to a national forum to complain that someone had stolen cash he’d left on a public bench. So why should anyone care that badly locked bikes are often stolen?
