Hitch racks are a popular way to carry bikes and gear as they offer a flexible and portable design that can work with nearly any vehicle equipped with a hitch. Saris’s Modular Hitch System or MHS rack is a modular approach to a hitch rack that provides a versatile way to carry one to four bikes as well as cargo by simply swapping out components. Saris lets you customize the rack by offering multiple base options, and removable attachments and additional accessories. It’s a clever system that currently features three base options: 1+1, 2+1 or the largest 3+1 which allow you to transport 2-4 bikes. Each base can be combined with either the DUO dual-arm tray or the lighter UNO single-arm tray or a MHS cargo rack for gear.
