Mountain bike and Downhill
Mountain biking (often abbreviated as mountain biking, acronym for Mountain / Trials Bike; in Italian, climbing) is a bicycle structured so that it can move even on asphalt roads, uphill and downhill. In general, it differs from other types of bikes, thanks to the suspension (almost always padded), but not only: the mountain bike actually has much wider tires and buttons compared to a racing bike. There are different materials that make up the frame of a mountain bike, for example aluminum, carbon, iron, etc. The difference is in weight, in fact carbon is much lighter than aluminum.
