Summary
The Trek Fuel trail bike is celebrated for its versatile performance, offering a balanced mix of climbing efficiency and descending prowess. Its suspension system, featuring the Active Braking Pivot (ABP) design, ensures that the rear wheel remains engaged and active under braking, providing a smooth and controlled ride over rough terrain. The bike's geometry is highly adjustable, catering to a wide range of rider preferences and trail conditions. With a sturdy, flex-free chassis and a suspension setup that delivers ample traction and support, the Fuel EX excels in both technical climbs and fast descents. However, some riders may find the 140mm of rear travel limiting on very rough terrain, and the SRAM AXS drivetrain and Code RSC brakes have been noted for occasional shifting hesitations and requiring more effort for full braking force, respectively.
Aggressive climbing ability
Slack steering angle for versatile trail handling
Adjustable geometry and shock progressivity
Solid climber without shock assistance
Impressive ability to smooth out rough terrain
140mm of rear travel may be limiting on very rough terrain
SRAM AXS drivetrain experienced occasional shifting hesitations
SRAM Code RSC brakes require more effort for full braking force
The 2023 Fuel EX will serve as Trek’s mid-travel do-everything trail bike, and it offers a near perfect ‘quiver-killer’ package.
BikerumorThe Fuel EX climbs like a hyperactive goat.
BikerumorIt’s as if the linkage is speed-sensitive, as it responds very well to all kinds of high-speed impacts.
BikerumorThe Trek Fuel EX 9.9 X0 AXS T-Type places you in a comfortable, upright pedalling position, with the weight evenly distributed between the front and rear.
Enduro Mountainbike MagazineThis bike lights up at speed; it charges the climbs, shreds the descents, and the ABP does a fantastic job keeping the rear wheel on the ground and engaged.

When Trek launched the all-new Fuel line last summer, I was eager to spend time on the Fuel LX, MX, and MLX configurations. I’ve spilled a lot of words about that bike here, here, and here, and it’s safe to say I’m fairly smitten with it. But Trek wasn’t content to just release perhaps the most adaptable trail bike of the year. They simultaneously announced a corresponding “+” line that takes the same geometry and features and slaps on TQ’s new HPR 60 motor and a 580 watt-hour battery. That means that you get the same absurdly adaptable platform, that’s easy to swap between a 145/150 millimeter 29er, the 150/160 millimeter mixed wheel bike I reviewed, or a 160/170 millimeter full 29-inch bike. And yes, the secret menu options are still available, although, as I’ll get into later, I actually prefer slightly different configurations with this bike than with the meat-powered version. Trek Fuel+ MX 9.8 Eagle 90 Gen 2, Travel: 150 mm (rear) 160 mm (front), Wheel Size: MX with full 29” capabilities, Size Tested: Large, Build Tested: 9.8 Eagle 90, Head Tube Angle: 64.2°, Motor: TQ HPR 60, Battery: 580 Wh, Measured Weight: 44.94 lbs (20.38 kg), MSRP: $10,199

For riders looking for a trail bike with more of a focus on the descents, the Trek Fuel EX, Propain Hugene, and Polygon Collosus fit the bill, and I'd personally rank them in that order, with the Trek on top. .
Very versatile, wide range of geometry and travel possibilities.
Well-balanced suspension feel.
Carbon and aluminum frame options, lots of models to choose from
It's more of an all-mountain bike than a trail bike; some riders may be better served by the Top Fuel.
One frame to do it all means it's not as light as it could be.

The new line of Fuel and Fuel+ bikes from Trek are doing more with less thanks to some unique and exciting design elements.

Although raced by Evie Richards on the elite-level cross-country circuit, Trek’s latest Top Fuel 8 Gen 4 is a bike that’ll cater to a raft of tastes thanks to its impressive adaptability. Despite the meagre suspension travel, it dishes out stellar trail manners up and downhill and is primed for UK trails.
