Bike mudguards, also known as fenders, are protective accessories attached to a bicycle's frame or wheels to shield the rider from water, mud, and debris thrown up by the tires. They are particularly useful in wet or muddy conditions, keeping the rider and bike cleaner and reducing the risk of dirt affecting the bike's components. Mudguards come in various styles and materials, ranging from lightweight plastic to durable metal, and can be designed for specific bike types, such as road, mountain, or commuter bikes. They are an essential accessory for riders who frequently ride in unpredictable weather or off-road conditions.
