State Bicycle 4130 Trail

The Soul of Steel, Unleashed.

"Rowdy, Reliable, and Ready to Rip."

The 4130 Trail is our love letter to the hardtail—the purest form of mountain biking. This is a bike for the rider who wants to feel the trail, not just float over it. It’s built around a tough, lively 4130 Chromoly steel frame that absorbs chatter and begs to be thrown into corners. We’ve paired that legendary ride feel with modern, aggressive progressive trail geometry and a plush 130mm RockShox fork. It’s a simple, durable, and incredibly fun machine that will sharpen your skills and plaster a permanent grin on your face.

This Is The Tool For You If...

  • You want a durable, low-maintenance bike for aggressive trail riding.
  • You appreciate the lively, connected-to-the-trail feel of a steel hardtail.
  • You're looking for a fun, playful bike to complement your full-suspension rig.
  • You want a high-quality, trail-ready mountain bike that offers incredible value.

Geometry of Fun

Confidence in the Chaos

This bike is engineered to party. The secret is its progressive trail geometry. Feel the unwavering stability of the slack 65° head tube as you point it down steep, technical descents. Sense the playful, poppy nature of the short chainstays as you manual through rollers and slap corners. It’s a tangible feeling of confidence that encourages you to push your limits, try new lines, and ride more aggressively than ever before. This is a geometry that’s all about maximizing your fun on the trail.

The Steel Feel

Tougher Than Aluminum, Smoother Than Carbon

There's a reason die-hard riders swear by steel. The Double-Butted 4130 Chromoly frame is the soul of this bike. Feel how it mutes the high-frequency trail chatter, taking the edge off of rough terrain and reducing fatigue on long rides. Sense its resilience as you push it hard, knowing it's built to take a beating and come back for more. It’s a ride quality that is both forgiving and lively, a perfect blend of comfort and durability for the real world of trail riding.
