"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.Read more
"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.'Read more
"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."Read more
'Simply put, nothing comes close to the Fuel EXe when you paint the picture of the mountain bike experience as a whole.'Read more
'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.'Read more
'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.'Read more
'We have to call it as we see it and the Trek Fuel EXe just elevated the eMTB game.'Read more
'The first impression was a unanimous "Wow". This is one of the few times that a bike exceeded expectations.'Read more
'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.'Read more

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.
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.
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.
The SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner-looking, it's also more precise under load and easier to set up.
TyreWiz monitors your tyre pressure while AirWiz monitors your fork and shock pressure. Set your desired pressure in the SRAM AXS app and then just check the lights before each ride – red means you need a pump, green means go and ride.
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trail-side adjustments and repairs.
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.
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.
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.
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.
