i actually had one like this except it was red and white which i eventually sold to gaskill if you need parts. they were sold in europe and china. they all had english 3-piece cranks and tanks with no horns. the seatpost bolt holds the rear wheel stays in place for they are not welded to the rest of the frame. . . i used that to my advantage when i stretched mine about a foot. the chinese frames were slightly smaller than the european frames such as the one i had. that's all i know and if anyone has any info contrary to it i'm sure they will supply it. nice bike, enjoy it!!
