We don’t recommend carrying four bikes on a trunk rack because it puts too much stress on the attachment points with your car. If you want to carry more, you’ll need to use a hitch rack or a combination of trunk and roof racks.

Many smaller cars can’t accommodate a 2-inch receiver.

The size of the hitch receiver tube also affects your choice: Most racks fit a 2-inch receiver fewer racks have 1.25-inch versions. Does (or can) your vehicle have a trailer hitch? If you have a hitch, we recommend a hitch rack if not (and if installing one isn’t possible), you’ll have to consider another style.
