Setting the Bar for Fat Tire Expedition Bikes

Maximalist off-road tourists, explorers looking to get off the beaten path, and survivalists for whom being stranded isn’t an option will all appreciate Pugsley’s wide footprint, long and stable wheelbase, and plethora of accessory mounts.

Since way back in twenty-aught-three, Pugsley has seen it all: intercontinental bikepacking trips, bushwhacking at its finest, mirages in the desert, and countless souls taking on the Arrowhead 135 ultra-endurance race. It’s seen some, shall we say, sticky situations, but it always finds its way out. Its proven track record gives it the calling card as the quintessential fat tire expedition bike.

“Any bike will get you out there. Pugsley will get you home.”

  • 135mm-space offset fork allows wheel swapability when the shit really hits the fan (and it will someday, trust us)
  • Every accessory barnacle you could ever need
  • 142 x 12mm-spaced rear dropout with a dedicated Rohloff torque arm slot
  • Clearance for 26" x 4.8" tires in the frame (with drivetrain restrictions), 26" x 4.3" tires in the fork
