Surly Big Dummy, Dark side of the Maroon
Big Dummy er transportsykkelen over alle transportssykler. Ikke bare er den praktisk og bærekraftig i dobbel forstand, den er også morsom.
I tilegg til å kunne frakte masse greier bakpå lastedekket eller i rammeveskene om følger med, kan sykkelens lastedekk også tilpasses ulike tilbehør alt etter hva du trenger transportere. Vi har hørt rykter om frakt av juletrær fra skogen, barn til og fra barnehage, matvarer, ja, til og med frakt av andre syklister som har punktert. Om du skulle ha behov for virkelig å dra på, har Surly også egne spesialtilpassede hengere tilgjengelige.
Big Dummy-rammen er spesialdesignet for sitt bruk og ikke bare en tilhenger festet på en eksisterende sykkel. Dette gjør Big Dummy stivere og mer motstandsdyktig mot torsjonsbøyning, noe som sørger for at sykkelen oppleves som både rask og smidig og gir deg en bedre sykkelopplevelse og mer robust ramme. Big Dummy trives like godt i byen som ute i skauen, og kan også skryte av å ha vært del av ulike forskningsprosjekt i regi av Universitetet i Agder med mål om å kartlegge transportsykkelen ulike påvirkninger i hverdagen.

- Weight Limit: 400 lbs. combined rider & cargo
Like all Surly´s frames, it’s made of their size specific, 4130 CroMoly steel – a tube set engineered for cargo that sports lots of little touches that you’ve come to love in a Surly like clearance for big tires and the use of common component sizes. Figure on being able to carry about 200 pounds (90kg) of cargo. The load weight, and how it’s loaded, will affect the handling somewhat. Also, plan on using gears, especially as cargo weight increases. This may seem obvious, but as you get comfy with it, you will use your full range of gears as never before.
The parts kit is good quality, and suitable to loaded as well as unloaded riding. It’s got a 3x10 drivetrain, Avid BB7 disc brakes, quality Shimano Deore hubs, and Schwalbe Big Apple 26" x 2.35” tires. We’ve outfitted it with our Surly-designed bags, deck, rails and Dummy Rail Collars; everything you need for the majority of stuff you might carry, like groceries, shovels, bags of charcoal or mulch, guitars, lamps, mannequins, whatever. Bags, deck, rails, and rail collars are all designed to improve on previous offerings and work together to make sure your stuff is transported with safety and stability. It’s an unbending interface, which when you’re carrying lots of cargo, is a good thing to have. Get creative, and get hauling.
If you intend to carry a passenger on your Big Dummy, Surly requires use of our Dummy Rail Collars. These provide a secondary retention system for the rack, as well as stiffen the rack system. These are included with MY18 Big Dummy bikes and frames, as well as available AM for older Big Dummy bikes and frames [compatible with all generations of Big Dummy bikes/frames]. In addition, a stoker handlebar set up, found on tandem bicycles, is recommended as well. Make sure to check with seat post manufacturer for stoker handlebar compatibility.
If you are planning to carry a child on your Big Dummy, Surly recommends the use of a child seat. They’ve tested the Maxxi Yepp seat. They make an adaptor that that allows their seat to mount onto our deck. It works well with the Big Dummy. At this time other child seats are not recommended and will void your warranty. Surly are testing other options. For the most up to date compatibility/options, check http://www.surlybikes.com/safety
Note: keep in mind Big Dummy weight limits when carrying a passenger.
