This is their Vertex 4 bicycle rack. A few quick notes about this bike rack. This bike rack will hold up to 4 bikes and is convertible between an 1-1/4 inch and 2 inch trailer hitch. The hitch switch allows the arms to fold when not in use and also tilts the carrier down for rear access of the vehicle. It does come with the hold fast cradles and the no sway cages standard. At the top of the bike rack the is a built in carry handle that makes it easy to transport the bike rack around. It also makes it easier to take it out of the vehicle and put it into the hitch. Lets go ahead and add the spacer to the stinger here, right now this is the 1-1/4 inch version. This is good for class 1 and class 2, 1-1/4 trailer hitches. However with the class 1 you are limited to just 2 bikes. Slide it over the top and we will install the bolt and the bike rack does come with included tools to do all this with.
