Weren't they marketed in the UK in the 80's by Falcon or one of the other 'major' brands? I seem to recall that the name was used for a short while to part sponsor a UK professional team - but they rode conventional bikes. There was a 'rumour' going round that one of the team pro's was going to tackle the end-to-end record using a version of one but it never happened. I wonder why???????????...........
