There are original manufacturers designed and generic fenders, (universally known in British English as mudguards) for bicycles that can be fitted to most bicycle frames. These catch and redirect road spray thrown up by the tires, allowing the rider to remain clean. They are increasingly common on bicycles in the more car dependent English-speaking countries, since bikes in these countries tend to be sports-oriented, with minimal clearance between tires and frame tubes for fenders, or were ridden only in mild conditions, although there are a few fenders that are designed to be attached to the seat post. The trend towards urban biking, which has doubled in the past decade, led to a production, import, and use boom in utility bikes. European utility bicycles, traditional roadsters, serious touring bicycles, and beach cruisers are nearly always fitted with fenders.
