Trek Fuel+ : electric trail bikes, elevated

More Fuel for your best rides

More laps. More reasons to keep going. Fuel+ is a pedal assist mountain bike for those who want it all — more miles, more trails, and more ways to rip. With a bigger battery, more powerful motor, and three dialed geometry setups, Fuel+ is made to get you to the good stuff faster — and keep going. Choose from a balanced trail build, a flickable setup for boosting jumps and railing corners, or a long travel build for rowdier terrain. However you ride it, Fuel+ keeps the ride quiet, natural, and ridiculously capable.

Quieter than ever

HPR60 delivers the award-winning performance that shook the industry on Fuel EXe, and gives you a boost that’s not just more powerful than its predecessor, it’s also quieter, too.

No more range anxiety

Fuel+ gets a big 580Wh battery, giving you 60% more range than previous gen Fuel EXe. And it’s not just a bigger battery, it’s also more efficient, so you get more miles on the trail per watt hour.

Fine tune for full send

One frame. Three ways to rip. Fuel+ is built on a truly adaptable platform that lets you choose the perfect setup to match your style and terrain — and then tweak it to your exacting specifications. Set it up as EX for well-rounded trail performance, MX for a playful ride that’s ready to boost, or LX for more travel and confidence for crushing the rowdiest trails. However you ride, Fuel+ gives you the freedom to dial in a setup that’s anything but one-size-fits-all.

Three beasts

Fuel+ EX

With 29” wheels and 145/150mm (rear/front) travel, EX is the classic Fuel+ configuration. You get the most efficient pedaling and the most balanced handling, making it the right bike for a massive variety of riders and terrain.

Shop Fuel+ EX

Fuel+ MX

Fuel+ MX is a side-hit savage ready for airtime. Short for mixed wheel sizing, MX gives you a quick-handling 27.5˝ rear wheel paired with a monster-truckin’ 29er in front. It’s ready to rip with 150/160mm (rear/front) travel and increased leverage rate for getting zesty on jump lines.

Fuel+ LX

Want a build that’s burly by nature? Fuel+ LX is a long travel trail smasher with 160/170mm (rear/front) travel and a full 29er setup. You get more travel and the most progressive leverage rate for the rowdiest riding — ideal for ripping a coil shock.

Dialed to be different

Many trail bikes allow you to swap 29ers for mullet or roll with different shocks, but most don’t adapt the frame to optimize your new setup. That means you end up compromising your ride with suspension that doesn’t feel quite right, off-kilter geometry, or a bottom bracket so low it causes pedal strikes on every climb.

Fuel+ is different. We don’t just throw on a few new parts and call it a day, because we don’t want your component selection to compromise the geometry or quality of your ride. All three versions of Fuel+ start with the same frame, but the magic in these builds comes from interchangeable rocker links and shock mounts that adapt the chassis for your dream build.

We started with the award-winning kinematics of Fuel EXe Gen 1 and flattened out the anti-squat curve to make it a little more efficient for summiting steep climbs. Plus, a boost in travel means it’s not just more efficient, it’s more capable, too.

Shop Fuel+ EX

Fuel+ MX uses an MX rocker link and lower shock mount. These parts not only bump rear travel up to 150mm, they also create a more progressive leverage rate for more aggressive riding. The MX rocker and lower shock mount correct the geometry for the smaller rear wheel, so you don’t end up with a bottom bracket that’s too low and causing pedal strikes.

Shop Fuel+ MX

Fuel+ LX uses the same lower shock mount as Fuel+ EX for a 29-inch rear wheel, but pairs it with an LX rocker link. Complete Fuel+ LX builds come with a longer, 65mm stroke shock. Pair that with the LX rocker, and you get 160mm of rear travel with Fuel’s most progressive leverage rate for the most aggressive riding.

Better geometry. Better ride.

1.
Massive dropper insertion

Fuel+’s new frame design lets most size medium riders run a 200mm dropper post.

2.
Dialed trail geometry

Larger sizes have taller stack height (vs Fuel EXe Gen 1) for better weight distribution when descending steep terrain

3.
Size-specific chainstays

Size specific chainstays give smaller riders better handling in tight corners and taller riders better weight distribution on climbs.

4.
Primed for smaller riders

Size small stock Fuel EX models come with an MX link and a 27.5 rear wheel for the best fit right out of the box, but it's easy to swap to a full 29er.

An open front triangle gives you tons of room for stashing big water bottles and additional accessories, like frame bags, mini pumps, or a Range Extender.

Tweak your leverage rate with the flip of a chip. Go less progressive for a plusher feel when you’re deep in the travel or more progressive for big features, more bottom out resistance, or running a coil shock.

New zero stack standard headset, allows for more aftermarket options, like angle-adjust headsets or tricked-out colors.

Top tube accessory mounts let you bolt on accessories, so you can easily stash essentials, like a multitool or flat kit.

Meticulously engineered chainstay guards keep your ride quieter through the rough, while updated downtube guards protect from rock strikes.
