Product Description

Surly: Big Fat Dummy - Fat Tire Cargo Bike - 2019

Haulin' Bikes

Surly are firm believers that you can and should spend as much of your day on a bicycle as possible. That includes commuting, kid-hauling, grocery shopping, hitting the hardware store and lumberyard, date night, and all other et ceteras. The long-tail cargo bike and bike trailers that make up their Haulin' category offer everything you need to leave your four-wheeled combustible vehicle at home and still run all your errands. Surly's cargo bikes have been likened to the modern-day minivan and their trailers make most pickup trucks irrelevant.

 

The Big Fat Dummy is a fat-tire, long-tail cargo bike from Surly that was specifically designed around fat tires; it has a longer toptube and slacker headtube offering the most stable, stiff, and predictable ride possible while hauling a lot of cargo.This bike is perfect for those who are looking to make bikepacking a family affair, and those that help maintain their local trails will appreciate the Big Fat Dummy hauling abilities.

  • Single-piece frame increases stiffness and decreases torsional flex

  • Human cargo compliant with the use of Dummy Rail Collars

  • Three-pack mounts, double water bottle bosses on seattube, internal dropper post routing

  • Clearance for 26" x 5.25" tires or 29” x 3.0” tires

 

Color: Thorfrost White, Biolet

NOTE: The Big Fat Dummy is only available in three sizes, which is a departure from Surly's normal way. Here’s the thing, its sizing and fit is a little different than other bikes. By using shorter seat tubes with a longer seatpost, two people of different heights can ride the same size frame. They found it works pretty well – hell the Large size even fits Sov. And nothing fits Sov.
