Alex is twelve years old and attends a school for children with special needs and mental development. He is autistic and has a developmental delay. He is a cheerful boy and enjoys going to school. Here he learns what he needs for life, he says. Including cycling. He would love to learn how to ride a bike. Even his little sister can do it now, only he can't, and he's 12. He is willing to give all he can. His teacher, Mr Lemke, has drawn up a training plan and his parents are also supporting him. Setbacks annoy Alex, but he doesn't want to give up this time. He has his sights set firmly on his goal: he wants to pass his cycling proficiency test, which will be conducted by a police officer in the school playground at the end of the school year.
