Reinvented. Ready for Anything. "Strength without Compromise." The 4130 Steel Line earned its namesake from the double-butted 4130-grade chromoly steel used on the frame and fork that maximizes strength without making compromises on weight. Now with completely redesigned geometry to accommodate larger tire clearance and equipped with fork and seat stay rack mounts to be the perfect all-rounder. Whether you're navigating poorly maintained city roads, exploring gravel paths, or hitting light trails, this bike is built to handle it all with style and simplicity. "The 4130 Matte Olive is our ultimate rugged, utilitarian build. We used double-butted Chromoly not just for weight, but for its fatigue life—it’s designed to handle a decade of city potholes and gravel paths while the stealth olive finish stays looking sharp despite the daily grind." — State Bicycle Co. Product Team THIS IS THE TOOL FOR YOU IF... You want a bike that can handle rough city streets and gravel paths alike. You value the simplicity, reliability, and low maintenance of a single-speed drivetrain. You appreciate the strength and smooth ride quality of a premium steel frame. You need a versatile machine ready for racks, fenders, and daily utility. THE SOUL OF STEEL Double-Butted Durability The heart of this bike is its frame. We use double-butted 4130 Chromoly steel to create a chassis that is incredibly strong yet surprisingly light. Steel is renowned for its ability to absorb road vibration, providing a smooth, comfortable ride even when the pavement ends. With a TIG-welded frame and a "Wishbone" rear, it offers ample clearance for larger 38c tires, expanding your horizons beyond the tarmac. ULTIMATE VERSATILITY Fixed, Free, & Loaded Equipped with a sealed-bearing flip-flop hub, this bike lets you choose between riding fixed gear for maximum control or single-speed with a freewheel for easier coasting. The redesigned geometry and inclusion of fork and seat stay rack mounts turn this simple machine into a capable commuter or light tourer. It's the perfect blank canvas for your cycling adventures. KEY FEATURES *Note: Detail images feature our standard Matte Black model. Your bike will arrive in the official Matte Olive colorway.

Here is the technical breakdown of why this bike outperforms standard commuters. Double-Butted 4130 Steel Unlike standard high-tensile steel, our 4130 Chromoly features variable wall thickness. It maintains a staggering 100,000 PSI tensile strength at the joints while shaving off excess material in the center, resulting in a frame that is 20% lighter without sacrificing durability. 16 Unique Skid Patches If you ride fixed, you know the pain of burning through rear tires. Our optimized 46/16 gear ratio is mathematically engineered to distribute your stopping friction across 16 unique skid patches, effectively tripling your rear tire life compared to a standard 48/16 setup. Massive 38c Tire Clearance We designed the frame and fork with a "Wishbone" rear to fit high-volume 38c tires. This rubber acts as a "natural suspension" system, absorbing up to 35% more road vibration than traditional 25c commuter tires, turning brutal city potholes into minor bumps.

Standover height ranges from 29.1" on the 49cm frame to 33.7" on the 62cm frame. We recommend measuring your actual inseam to ensure at least 1 inch of clearance over the top tube. Can I ride this bike if I’ve never ridden a fixie before? Yes. Every 4130 ships with a Flip-Flop Hub, allowing you to easily switch between Fixed Gear and a standard Single-Speed Freewheel that allows you to coast. Does the Matte Olive model come with brakes? Yes, this model includes both front and rear dual-pivot caliper brakes and levers, making it 100% street-legal and safe for urban riding. What is the benefit of a 4130 Chromoly Steel frame? 4130 Chromoly is double-butted steel that is stronger and lighter than high-tensile steel, offering superior vibration dampening for a smoother ride on rough pavement. What is the gear ratio on the 4130 Matte Olive? The bike features a 46x16 gear ratio. This setup is optimized for city commuting and light gravel, providing a balanced blend of climbing torque and flat-land speed. How much does the 4130 Fixed Gear weigh? The average weight is approximately 23 lbs 7 oz for a 55cm frame with riser bars, providing a stable and planted feel in city traffic compared to lighter aluminum models. How often should I tension the chain? We recommend checking tension every 100–200 miles. Horizontal dropouts allow for easy adjustment to prevent chain drop and ensure a quiet drivetrain. What tire pressure should I run in the stock tires? We recommend 90–110 PSI depending on your terrain. Lower pressure increases comfort on bumpy gravel roads, while higher pressure minimizes rolling resistance for maximum speed on pavement.
