Overview

"Fuel EXe's natural-feeling assist and stealthy good looks earned it a coveted spot on TIME's Best Inventions of 2023 list."

'That tiny harmonic pin ring drive unit is the golden goose of e-bike motors.' Find out what Pinkbike had to say about the revolutionary motor at the heart of the Fuel EXe.

"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."

'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.'

"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."

'Simply put, nothing comes close to the Fuel EXe when you paint the picture of the mountain bike experience as a whole.'

'The Trek Fuel EXe is the bike (e or otherwise) that plenty of people have been waiting to see… Removes the final few issues that the e-curious crowd had.'

'The Fuel EXe is such a harmonious package that I got comfortable with it very quickly, and it wasn’t much longer before I was in love with this bike... I legitimately forgot that I was on an e-bike at times… it’s the most natural-feeling motor I’ve yet ridden.'

'We have to call it as we see it and the Trek Fuel EXe just elevated the eMTB game.'

'The first impression was a unanimous "Wow". This is one of the few times that a bike exceeded expectations.'

'There are times when I am left amazed by something new and shiny, and that is the case with the Trek Fuel Exe... I might even go as far as to call it an engineering marvel.'

Features

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.

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.

Learn more

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.

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.

See battery features

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.

Install angle-adjust headset cups (sold separately) to tweak the head tube angle a degree steeper or slacker to your liking – all without impacting your bottom bracket height.

How it works

Shimano Deore brings even more adventure with a wider range of gear choices for the steep stuff, the fast stuff and the fun. With smooth riding, improved chain stability and sharp shifting, Deore heightens your mountain biking confidence and control so you can focus on the trail and enjoy the ride.

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.

This suspension calculator will help you optimise your suspension settings for your riding weight. Simply follow the steps to find your best set up.

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.

Toggle between assist modes or engage the walk-assist function with the ergonomic low-profile remote.

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.

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.

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.

Sizing

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
