Five friends on bicycles. Cheerful, energetic, optimistic. Backpack on their shoulders. They've decided to go on a trip. They leave the city and already breathe freedom. The first part of the route is on flat ground, the second uphill. And on the hairpin turns, it gets tough.

Gianni gets a flat tire: but he's quick and skilled, and it doesn't take him long to fix the tire. Gianni is tired and suggests five minutes, then ten minutes of rest will be granted. The five friends lean their bikes and sit on the roadside. It's the first opportunity to chat and compare notes.

This pedaling is also a journey of discovery: of oneself, of others, of the territory, of life. And so the encounter with Pierina the farmer, with Silvano the cyclocross champion (and his bicycle baptized Attila), between the ford of Rio Tauneri (but for them it's the Rio Grande, "a river explored by people like them is either Grande or nothing") and a snow adventure ("K.O.?, Mario immediately asks, scared. O.K., O.K., Mario, Mike responds"), a countryside dinner and the greasy pole contest...

"O.K. or K.O.?" is a small book that emerged in a book crossing. It was written by Piera Paltro, published in 1975 by Paolo Viano International Bookstore in Turin, the price is not indicated, just as the author of the fourteen illustrations, including the one on the cover, is not mentioned.

Stories for young people, with gems of wisdom. Starting from the first chapter. "It is man who has given value to money, but now it is money that gives value to man", "I like to take a nice bike ride, and if there's an uphill, even better, because I enjoy it, because I feel alive, because I overcome a difficulty and I make it and arrive", "Adults like to play, but only up to a certain point. Then they have to complicate things, like seeing if they can gain something, if people admire them, if at some point they become the most famous".

O.K. or K.O.? O.K.!
