Hitch Racks

Bicycle hitch racks will require a hitch or receiver and these come in 2" and 1 1/4."  Most cars and trucks do not come with a hitch receiver, unless this was a purchased option, and you may have to purchase it and have it installed aftermarket.  2" is the most common receiver type (and is what most trailer hitches require), whereas 1 1/4" receivers are generally for lighter accessories such as bike racks.  It is important to note that not all bicycle hitch racks are made in both 2" and 1 1/4" receivers, however many are "universal" in that they can accommodate both sizes with an adapter.
