As a birthday gift, Sasha, a character of undefined gender, gets a green bike. Sasha loves it and decides to call it Azar. But Azar is a talking bike, just like any bike for those who can understand. Moved by this new friendship and very knowledgeable about bikes around the world, Azar decides to send Sasha on a wonderful journey aboard the most extraordinary vehicles; a penny farthing, a bike sauna, a unicycle, a velomobile, a sail bike… and many more! The story ends with Sasha returning home to his friend Azar on a flying bike. A black and white picture book with flashes of colour in honour of the bicycle, in all shapes and sizes, often a child’s very first means of transport.
