Devinci’s 2019 AC salutes those about to rock with the kind of slack, aggressive roll you’d expect from the spawn of Spartan—and with the extra oomph of an e-equipped engine. Tame turbulent descents thanks to a generous 170mm of rear travel meets 180mm of finesse in the fork. And then turn around and hit turbo on the uphill. The Shimano STEPS E8000 engine boosts you to speeds of up to 32 km/h (limited to 25 km/h in Europe). The drive unit is controlled via a left-hand power-mode switch that triggers three settings (ECO, TRAIL and BOOST) for varied terrain. Crank the volume and cue the bangers. The AC is an e-beast that shreds.
