Extreme Off-Road Expedition Bike
$1900 USD / $2599 CAD
Pugsley is the ultimate expedition bike tailored for off-road touring and exploration.
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.”
NOTE: You can ride your bike wherever the hell you want, but this is what we think this bike is best at.
