Surly's Bill Trailer is brilliantly engineered to carry almost everything! This seriously stout workhorse is built from chromoly with stainless-steel hardware for excellent durability and it rolls on quality 16-inch wheels and tires. There are even fenders. The trailer sits perfectly level as you ride, so even heavy and bulky items stay secure. You can tote up to 300 pounds of whatever on this bad boy! So go ahead, run all your errands by bike — you'll be smiling when you get back home. Please note that the required Surly hitch for this trailer is sold separately.
