I am currently in the process of restoring one that was given to me by a friend who has more Bickertons than he really needs. The frame hinge was bent, I think due to someone too heavy for the bike riding it, or hitting a big pot hole. I have machined a new one which will hopefully last a lot longer. These bikes have really started to grow on me and can be quite nicely restored, see Elvis Shumaker's restoration here:

Production of the first generation ceased in the 1980s and replaced by a re-badged Dahon, which I believe also ceased in the 1980s. Its good to see the name back again and that Mark Bickerton is behind the relaunch. The new bikes look very nice.
