I saw this movie in the early-mid 90s. The scene I remember most is at the start of the movie this kid tries to do like a trick on a skateboard ramp and he totally wipes out in front of the bulky kids. then at the end of the movie he tries the trick again and he likes flies through the air and all the bully kids are like OMG! And there’s like a group of kids on bikes and skateboards and stuff and they all meet in like this abandoned outdoor warehouse/garage place. Ring any bells?
