the F 1 bnikes got " invented" by Shimano as a design contest ... marketing stuff idea kinda thing ..
Shimano gave their top 50 customers a "grouppo" with a nifty spring loaded 2 speed derailleur ... the idea was parking lot racing a la bmx which had a little slowdown and few parts from SHimano ( Tange was big in these days and dia compe and suntour and and ...)
I think HAro won the contest but there were quiate a few other cool ones out there. Mongoose was Mongoose at the time ..lol and they had one ... Schauff made a couple ( German bike manufacturer were I was workin ) Schwinn had one .... they never sold it was one of those flops ... maybe it was just lightyears ahead of its time ..lol

cool little bikes .. too heavy usually but cool
