Surly Big Dummy

Big Dummy D500 005a

The Big Dummy is a great bike AND a great cargo bike. The mainframe is double-butted 4130 CroMoly steel (that’s bike-speak for quality tubing). With 4 sizes, it offers bike fit options not available from other cargo bike brands. It’s versatile and fun to ride. Choose either a stock Big Dummy (special order) or one of our custom builds.

Our stock build differs from the Surly stock bike. Why our own build and not Surly’s stock parts? We have several reasons:

1. Tougher  wheels – our build includes wheels hand-built by an expert mechanic. That means you’re less likely to experience broken spokes and out-of-true wheels
2. Fewer flats - we complete each wheel with the highly puncture-resistant combo of Schwalbe Marathon or Big Apple Plus tires and Slime self-sealing tubes. Because, the best way to fix a flat on a cargo bike is to avoid it in the first place!
3. Customized cock pit - Aggressive,  up-right, or somewhere in between? You choose your riding position. We have several handlebar and stem options in stock and customize your Big Dummy to fit you and your riding style.
4. Xtracycle accessory compatible - It’s not that the Surly accessories are bad, it’s just that the Xtracycle accessories are SO AWESOME we think you’ll prefer them without a doubt! If you want a Hooptie or Yepp seat compatible deck, you’ll want the Xtracycle deck that we stock on our build.
5. No Fuss personalization - We can upgrade components such as pedals, seats, seatposts, grips to your preference . If our vendors stock it, we can spec it; you pay only the difference in price and no penalty for getting what you want.

More about the Big Dummy

The Surly Big Dummy is the perfect longtail bike. The sturdy frame, constructed from TIG welded CroMo steel. We add quality components like the Shimano drivetrain and disc brakes to augment this very functional bike. Four water bottle mounts and room for wide tires means this bike is at home in the city and in the middle of no where.

Load your groceries, load your kids, this option gives you endless possibilities. AND with a 400-pound rider & load limit, you’ll have lots of fun exploring those possibilities. The Big Dummy’s purpose built  single-piece frame means a stouter, more torsionally rigid bike that’s not only more resistant to fatigue and failure, but also more stable under load.




Splendid Cycles stocks a great selection of Xtracycle accessories so you can customize your Big Dummy to fit your needs.
