For his birthday, Juli received a bicycle - and it was definitely needed. But it still has training wheels! Wanja thinks Juli might as well ride a tricycle again, and Carolin also believes it's a baby bike. But soon Juli will be able to ride without training wheels, and that truly feels wonderful. And if Juli hadn't flown into a puddle during a race, and if his foot hadn't slipped off the pedal, he would have definitely won, logically. Besides, the two of them cheated. But when Juli then beats the much older Dennis on the moped, Juli experiences that wonderful happy feeling again.
