Bulletin: As our customers chose the Yuba Mundo over the Big Dummy by ratios of 20:1 or more in the past couple of years, we’ve stopped making a point of keeping the Dummy in stock, as much as we like it. We’re more than happy to special-order one for you.
Surly Big Dummy: very stable up to about 100 lbs. plus pilot
Yuba Mundo: very stable to about 200 lbs. plus pilot; the bike is rated for much more, but differences in individual riders’ abilities make it hard to say how easy it is to push that much weight.
Surly’s Big Dummy ($1799 complete) has a single, purpose-built frame. Big Dummy is similar to the Yuba Mundo but 15-20 lbs. lighter, more expensive, and generally spec’d with better components, e.g., disc brakes, bags, and a kickstand are standard on the Big Dummy but extra on the Mundo. It can’t stably carry nearly as much as the Mundo, however. It’s rated for about 200 lbs. of cargo vs. over 400 lbs. for the Mundo. In reality, you start to feel a difference in stability above 100 lbs., and that’s where the Mundo takes over the game. For riders wanting to haul up to 100 lbs., however, the Dummy is a great choice. It’s also compatible with all XtraCycle accessories and some Mundo accessories as well.
The photo above shows you how a single set of stoker handlebars, with an extra-long stem mounted to the seatpost, can be used by two kids at once.
Big Dummy comes in several frame sizes.
The Big Dummy is built from 4130 CroMoly
steel. Surly designed it to be torsionally rigid while offering some
vertical compliance. The Big Dummy features disc caliper mounts and
cantilever brake pivots, clearance for 26 x 2.5″ tires and fenders,
multiple water bottle cage mounts, and a sturdy kickstand. You can purchase a Big Dummy frameset ($900) and set it up
with mountain components, road components, or a mixture of both. There
are no chainring clearance limitations…except the ground, so you can
gear it as high or low as you like. The included 425mm axle-to-crown
CroMoly fork can be swapped out for an 80mm-travel suspension fork
without radically altering the steering geometry.
