Take Your Longtail Bike Anywhere

Since its introduction in 2008, many a family have ditched one or both of their cars thanks to Big Dummy. We’ve also seen many entrepreneurs and small business owners minimize their carbon footprint and incorporate Big Dummy into their business model.

Big Dummy is a dependable grocery getter, the modern day mini-van, the company car, and a human-powered car replacement. It’s all those things and more in that there’s no limit to what it can haul — as long as it falls within the 400-pound weight limit.

Dedicated single-piece frame increases stiffness and decreases torsional flex
Human cargo compatible with the use of Dummy Rail Collars
Vertical, 135mm spaced dropouts with fender eyelets; Rohloff compatible
Clearance for 26" x 2.5" tires with fenders
400-lb. combined rider and cargo weight limit
