Spencer Wright at Traffic Cycle Design has created the Chupacabra, an imaginative all-terrain longtail taking cues from Surly’s superfat Pugsley and the forthcoming Big Dummy. This is the kind of ride you’d want if you were bike camping, say, from above the arctic circle in Alaska to Tierra del Fuego along the spine of the Rockies and Andes. It’s not for show. It’s for real: see Riding the Spine for a chronicle.
