When asphalt ends and the world goes wild- ragged snowfields, crunchy sand, frozen forest paths- that’s when the KHS 4 SEASON 4000 Fat Tire Electric Bike shows true grit.
Built on a high-modulus full-carbon frame with a tubeless- ready 26" × 4.8" tire set, this bike isn’t just built for rough terrain- it’s forged for freedom.
Imagine tires biting into fresh snow, or floating over sandy trails, while the road behind you disappears.
The 12-speed drivetrain, hydraulic disc brakes, and dropper post whisper reliability- over hills, through forests, beyond winter’s bite.
This isn’t a “seasonal option.” It’s your invitation to ride the world on your own terms. Wherever your heart leads.
Ride hard. Ride far. Ride 4 SEASON 4000.
