Need help naming an old anime...

[sanchan]

I remember watching it years ago in the early ninties and as far as I can remember it was an anime movie. Anyway it was about a boy and he had this red bike that turned into a robot thats al i know

I don't know if it turns into a robot and I probably haven't seen the movie myself, but this one is old, it's about a boy and he has a red bike: Akira.

Is this the one you're talking about?
