I'm looking for two karate movies don't know their names.One in which the kid is trying to get in shaolin in the end he got to pass the final test fighting dolls in some cave, And the other one was also with a kid who was training real hard for champion sheep but he was having problems wit some karate boy gang I remember a scene in this movie where kid was running next to black guy on bmx and he was faster.

Can't help with the first, but the second one sounds like "No Retreat, No Surrender".
