luggage capacity

A luggage carrier, also commonly called a (bicycle) rack, is a device attached to a bicycle to which cargo or panniers can be attached. This is popular with utility bicycles and touring bicycles.
Bicycle luggage carriers may be mounted on the front or rear of a bicycle. The rear mount is more common. Racks on the front are mostly reserved for utility and cargo bikes. A special type of front rack is a low rider which is mainly used for bicycle touring.
The term luggage carrier can also refer to a device with two wheels used to wheel luggage or something of similar weight from one place to another, similar to a dolly (hand truck) but lighter and usually able to be folded up.
