The Surly Pack Rat is designed around porteur-style racks and front-loading optimization, with a front cargo-specific design to eliminate steering issues. The fork features internal routing for generator hubs and rear frame dropouts to accommodate multiple drivetrain configurations. It’s an ideal choice for loaded commutes and bike trips with a lighter load, but also rides great when unloaded.
