The Extrawheel Nuts allow you to use the Extrawheel Trailers with bicycles which have a solid axle and utilize nuts instead of a quick release. The Extrawheel Trailers do include a hitch attachment of your choice.
Before getting extra nuts or replacement nuts, be sure to determine the correct size for your bicycle’s solid rear axle. The size of your rear axle can generally be determined by looking it up in reference to the manufacturer of the rear hub.
If you can not determine the size of the rear axle through the hub manufacturer’s brochure or online information, you can determine axle size by removing one of the nuts and taking it to a hardware store or local bike shop. Determine its size by checking which size axle (or bolt) it will thread onto.Check out our Extrawheel Nut size guide in the specs section.
