Description
The Surly Big Dummy is a 26″ longtail cargo bike in Twilight Zone blue, designed to carry a rider plus up to 200 pounds of cargo smoothly and with ease. Built with a large steel frame made from 100% Surly 4130 Chromoly Natch tubing, it features double-butted main triangle and fork blades that are TIG welded and coated to resist rust. The bike includes a Dummy Deck, Dummy Rails with two Surly Dummy Rail Collars for added stiffness, and Big Dummy Bags Version 2.0.
