Built on a high-modulus full-carbon frame and fork, the KHS 4 SEASON 5000 Fat Tire Electric Bike brings real performance where lesser bikes stall.
Its 26" × 4.8″ tubeless-ready tires (Maxxis Colossus) deliver unmatched traction and float- whether you’re carving through deep snow, plowing sandy trails, or powering over rocky terrain.
Paired with a 12-speed drivetrain and a premium Shimano XT rear derailleur + shifter, you get smooth, reliable shifting across steep climbs and fast flats.
When you need to stop- or control speed- Shimano 4-piston hydraulic disc brakes give you powerful, consistent braking in all conditions.
This isn’t a “nice-to-have” winter bike. It’s an all-season, all-terrain machine for riders who demand versatility and performance- snow, sand, mud, rock, or hardpack.
If you want a bike that doesn’t just handle rough conditions but conquers them, the 4 Season 5000 is the one.
