I need a way to haul about 9-11 beach cruisers about 6-8 times a year. I drive a Hyundai Accent and already have a trailer hitch and a bike rack that holds 5 bikes. That has a 300lb tongue capacity and i believe my car has about a 1000lb load capacity.

Am I better off getting a roof rack to put 4 more bikes up there or would it be better on my car to pull a trailer with the bikes on the trailer instead?
