One of my buddies bought one brand new and it has the same problem. Also, I bought that locking mechanism off thorusa (the old one broke) so it's got to be the way the bike and lock are designed, not that it's bent or compromised.

There's a bike blog where this guy put a Dahon Mu handlepost on his boardwalk s1, but he also had to modify/replace the forks and do some other stuff. I just want to know if there's an existing handlepost I can buy and put in the place of the dahon boardwalk handlepost.
