Whenever this topic comes up I always say "BMX Bandits" which I believe to be Nicole Kidman's first movie.
It was made in 1983, so it is pretty bad!
Breaking Away had a lasting affect on me. I haven't seen it for 15 years but I still remember the scene where
the cyclist is tailgating the semi-trailer. Something I do enjoy when the opportunity arrises.
CHEERS.
