The bike had almost all the important features that Billy had been looking for. It was light, made of quality materials, and it had good brakes. After all, safety is the most important thing, isn"t it? But there was something that Billy didn"t like about the bike. The tyres were not really suitable for the trips he wanted to go on. And he had serious plans. He was going to the mountains and on a trip around the country. He needed something durable, something that would provide safety in all weather conditions, a product that would be good for stony or hilly areas. The tyres in the bike that he was going to purchase were definitely too narrow for that. He needed something wider and with a deeper tread. Fortunately, he hadn"t come to one of those huge sport shopping centres where the employees are not specialists at anything. Right, they have general knowledge about all the products, but they will not give you specific advice. He had decided to visit a shop owned by real experts. They offered him another set of tyres immediately, and they even fitted it for free. This is what service should look like. Three days later, Billy set off for the first ride in the mountains. He was sure he had made the right choice.
