El Oso de Acero Camo

Is it possible to call a fat bike sleek? El Oso de Acero’s classic steel lines look almost elegant when compared to other fat bikes. Steel has long been the favorite of bicycle frame makers due to its strength, ride quality, and aesthetic. These tubes are butted and heat-treated, giving the bike a level of compliance on top of what the roomy tires provide. Designed to get you and your gear out in the backwoods as easily as possible, El Oso de Acero is equipped with a full complement of solid Shimano parts. With a 3×9 drivetrain, rack mounts, and a spirit of adventure, it’s a dependable workhorse for those seeking something new out of a bike. With more traction than any bike’s allowed to have, it’s a rockcrawler, a dune buggy, and a snowmobile. In white or camouflage, El Oso de Acero is ready to help you get lost!
