The Sidecar Bicycle, built in Brooklyn, New York, by the Horse Brand Co., is a single-speed commuter whip with an attached third wheel and platform that will hold up 100 pounds of cargo (which is, coincidentally, the weight of a pony keg). With that much hauling capacity, it makes your car damn near obsolete.
The standard build includes a hardwood oak platform that can be mounted with racks and bins. You can also request a platform made from reclaimed Coney Island Boardwalk salvaged from Hurricane Sandy.
Horse only offers one size frame, with an adjustable seat post and a 57-millimeter top tube. Final touches include Brooks grips and saddle.
