BMX bike called the Rumblefish. It was featured in BMXplus in July 1991. The frame configuration is very similar to the jad, but the down tube is oval, it has hydrauic brakes, takes a slotted seat post and has an eccentric bottom bracket(you don't adjust the chain at the dropouts). It's a very rare bike, only about two dozen were produced to my knowledge. They were made by a fellow named Richard Kerr.
NOT a rumblefish frame
1993 Rumblefish 24" complete
Very odd frame design. I happen to have seen this one personally.
