Saris’ latest offering is one of the most configurable hitch-mount systems available. Since this rack is sold as a Base with add-on bicycle or cargo basket attachments, you can build this rack to meet your carrying needs or budget. For 2-inch receivers, Saris offers the Base in two sizes: 2+1 (up to three bikes or one bike and a cargo basket) or 3+1 (up to four bikes or two bikes and a basket). For 1-1/4” receivers, the 1+1 Base fits up to two bikes and cannot fit a basket. The bike holder options are 1Up-style dual-wheel arms (MHS Duo) or a slightly less-expense single-arm holder (MHS Uno). Both options held bikes securely in our drive-testing, though the MHS Duo feels more robust (the bikes did not sway as much). The rack holds bikes up to 80 pounds in the inboard position(s) but only to 35 lb. in the outer add-on (+1) spot. This may limit some riders’ choices if carrying multiple e-bikes or downhill/enduro rigs.
