The Epocalypse blends gravity-fueled capability with the power of Shimano's EP801 motor, delivering 85Nm of pedal assistance and backed by a robust 630Wh battery for endless trail sessions. Its 166mm of rear travel and 170mm fork sit atop 29" wheels, offering a ride stance inspired by Evil’s Wreckoning to conquer everything from steep descents to playful singletrack.
This genre-blurring e-MTB turns downtime into all-out adventures. Its low-slung motor placement and agile geometry make it equally ready for forest shredding or bike park send-offs, leaving your couch unbothered while you rack up miles.
E-Bikes are available for Pick Up In Store only. We are not able to ship e-bikes.
