Fuel EXe 8 is a trail-ready aluminum 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. You get all the tech of our top-end light e-MTB without a price tag that makes you say ouch Its upgraded FOX suspension package smooths the trail while 12-speed Shimano XT drivetrain shifts clean under load Its tiny but mighty TQ motor is tuned for the trail, keeping things quiet so you can stay in the moment, and ramps up power with you for a natural ride feel The integrated display, charging port, and controls are simple to use, sleek, and intuitive You can tweak your geometry with Mino Link, or add an adjustable angle headset to take even more control TQ-HPR50 – small, quiet, mightyThe TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio.
