<P> 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 . </P> <P> In the UK it is a legal requirement that a motorcycle should be fitted with mudguards . While motorcycles are invariably fitted with mudguards, only touring cycles generally have fully functional mudguards . Some machines can be seen with a stub of a mudguard only a few inches long, which satisfies the legal requirements but does not actually provide any protection from thrown mud and spray . </P> <P> Sporty - styled or racing motorcycles sometimes come with, or have added as an aftermarket accessory, a "hugger" rear fender, attached to the rear swingarm and very close to the tire, rather than attached to the rear subframe and away from the tire . Conversely, the practice of removing the front fender and reducing the size of the rear fender produced the bobber customization style of the 1950s onwards . </P>
