I bough the Lock n Roll by Zéfal for a Oyama folding bike, only to find out that the saddle lock won't work (the lock can't go all the way on that bike) and the wheel axises are for standard bikes anyway.
I was wondering: Are there locking skewers at all for folding bikes? Google reports a couple of well-known brands but I don't know if they fit on 20" wheels:
Winfried, I don`t know if there`s a specific problem with the skewers that I can`t see, but I`ve cut down a lot of bolts before, and after cleaning up the threads with a grinder or file, there`s no problem getting a nut on and off. The only problem I see is if the threaded portion is too short. If it is, maybe there`s a way to take the threaded rod out, shorten the unthreaded end, and pin it back in place? I`m guessing the threads are rolled rather than cut, so extending the thread length requires a special thread roller, which would make it almost impossible to do without spending a small fortune.

The problem is two-fold:
1. No brand seems to offer locking skewers for folding bikes, which means getting the smallest standard skewer and find someone to shorten them. I don't have the equipment nor the skills to do this
