What makes a cross-country electric mountain bike truly capable of tackling the toughest trails, and are manufacturers just slapping motors on existing designs or are they actually rethinking the entire bike from the ground up? Are the characteristics that define a great XC e-MTB - such as suspension travel, wheel size, and geometry - being reevaluated in the face of electric assist, or are we just seeing a bunch of Frankensteins monsters cobbled together from existing parts bins? Can a bike thats designed to be efficient on pavement and smooth singletrack really be adapted to handle the rough stuff, or do we need a completely new approach to e-MTB design? And what about the elephant in the room - battery life? Are we sacrificing range for the sake of saving a few pounds, or are there legitimate innovations happening in the battery department that will allow riders to tackle longer, more demanding routes without running out of juice?
