Does anyone know if it's possible to get hold of a folding seatpost from anywhere? I have an Apollo folding bike (heavily modified) and my main issue with it is that the seatpost just drops into the frame using a quick-release seat clamp when the bike folds. The trouble with that is that I may be commuting on the bike, but I can't leave it locked up all day because of the risk of someone stealing the seatpost. Is there some manufacturer that makes a folding seatpost? If I had one, I could simply use a standard clamp with a bolt in it, which would at least deter opportunists from taking the seatpost.
Thanks in advance
