I have a BMX bike that I built up from a frame I bought in a small bike shop in Bristol in the 90s. They said at the time it was a prototype by a MTB frame builders called Coyote. I was wondering if it was or could anyone shed any light on it. I have attached some photos of the bike. the serial number on the bike is BX 60591. There was a later MTB and BMX company called Coyote that were cheap taiwanese bikes it's not one of them.
