A skirt guard, dress guard or coat guard is a device fitted over the rear wheel of a bicycle to prevent a long skirt, coat or other trailing clothes or luggage from catching in the wheel.
These guards also help prevent a child’s foot from becoming entangled in the spokes when they are seated on a rear child seat.
Skirt guards are common on bicycles in Denmark, where the bicycle is commonly ridden in smart-casual or formal clothing; but very uncommon in other parts of the world where many cyclists wear specialized cycling gear. It is often paired with a chain guard to keep the rider’s clothing clean. They are often used on classic style comfort or utility bicycles used for every day commuting.
