KHS 4 Season 500

Engineered for pure fun across snow, sand, and rugged trails, the 2025 KHS 500 is a true all-season fat bike built to take on whatever terrain you throw at it. Its frame is crafted from 6061 aluminum with custom-formed top and down tubes, internal cable routing, a replaceable derailleur hanger, and a tapered 1.5" headtube.

The drivetrain is simple yet capable: a 1×11 speed setup with a 30 T narrow-wide chainring driving an 11–51 T cassette, handled by a Shimano Deore RD-M5100 and SL-M5100 shifter. Stopping power comes from Shimano MT200 hydraulic disc brakes (180/160 mm rotors) for confident modulation. The 26 × 4.8" Vee Avalanche tires, laced to 80 mm aluminum rims and sealed bearing hubs, deliver flotation and traction across loose surfaces. A riser bar, forged stem, and KHS dual-density saddle round out a setup that balances control, comfort, and durability.

Whether you’re plowing through powder, carving beach dunes, or stomping down muddy trails, the 500 is built to keep you rolling all season long.
