Best All-Around
"Overall, the Trek Fuel EXe is a bike that ranked consistently well across the board when it came to performance on the trail. It does everything pretty darn well and would be a great jack of all trades lightweight eBike for those looking to have a mid-power eMTB for trail shredding fun."
2022 Gear of the Year
'This is the first time an e-bike has made my Gear of the Year list [...] in addition to being silent, the HPR50 motor feels frictionless while pedalling. The assistance comes on with a subtlety that makes it feel like you are a younger, fitter version of yourself with a tailwind at your back.'

Editor's Choice
"The low-key, silent assist is just enough, keeping it riding like a real mountain bike but making the climbs less miserable. Don’t get me wrong, I love a good high-power eMTB, but I loved this bike, too. The Trek Fuel EX’s handling is dialled, and this is merely an enhanced version of that. I tested the top model, but, fortunately, there are also mid-priced models that eschew some of the AirWiz(ardy) without giving up any of what makes this bike rad."

TQ-HPR50 – small, quiet, mighty
The TQ-HPR50 motor is super-efficient with an amazing power-to-weight ratio. Most motors use gears and belts that take up space and can make noise or break. The TQ-HPR50 uses a harmonic pin-ring drive transmission that’s small, ultra-quiet and unbelievably natural-feeling.
Range Extender
Give yourself 40% more range with an optional 160 Wh external battery. It fits in a standard bottle cage and doesn’t require any complicated wiring or special mounts.
Connect, customise, calculate
The Trek Central app seamlessly connects with your bike for custom motor tuning, activity tracking and more ways to analyse and personalise your ride. You even get navigation features and real-time range calculations.
Removable battery
The 360 Wh battery gives you power for 2-5 hours. It’s concealed in the downtube, but it’s still easy to remove for more convenient charging.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
You almost forgot your pedals
This bike doesn’t come with pedals because you'll have a better ride if you choose your own. Explore the pedal guide to find the best pedals for your riding style. Reach for flat pedals for simple versatility or go for clipless MTB pedals if you want control and efficiency.
See the guideSuspension Calculator
This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.
Learn moreComplete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.
Learn moreIntegrated display
The Fuel EXe's display is simple to use and protected in the top tube. Check your assist level, range, speed and more at a glance.
Sleek and simple remote
Toggle between assist modes or engage the walk-assist function with the ergonomic low-profile remote.
Easier internal routing
Integrated channels in the frame make it easy to route the brake hose, dropper and derailleur housing so you get a clean set-up with no hassle.
Rapid Drive 108 rear hub
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
Oversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
