The Trek Fuel EXe 8 is a trail-ready aluminium electric mountain bike that quietly assists you on the climbs so you've got all the power you need on descents. Like its carbon counterpart, it looks and handles like a traditional trail bike, but with the added support of a tiny-but-mighty harmonic pin ring drive system with sleek top-tube display unit and compact remote. It comes ready to rip with upgraded parts where they matter most, like a FOX suspension package, wide Bontrager Line Comp Tubeless Ready wheels and a Shimano XT 12-speed drivetrain.
Sunset Cycles offers the 2025 Trek Fuel EXe 8 XT full suspension e-bike in Nautical Navy finish with free delivery.
