This a a basic utility trailer that is 6.5ft wide by 12 feet long. You can use it to haul yard debris, furniture, motorcycles, atvs, etc. I have used it as a motorcycle trailer most of its life. There are currently 3 wheel chocks on it but it can only hold a max of 2 bikes. The center is for single bike hauling. You could possibly fit 3 dirt bikes but that is at your discretion as I am unsure if it would fit.
