Summary
The Trek Fuel is a versatile and well-balanced trail bike that excels in a variety of terrains, offering a neutral, light feel and efficient suspension performance.

Some reviews note its conservative geometry and component choices as areas for improvement.
Versatile and well-balanced for all-round trail riding
Neutral, light feel with efficient suspension
Comfortable and easy to ride in a variety of terrains
Solid downhill performer and efficient climber
Adjustable shock settings for personalized ride
Geometry isn’t as radically aggressive as some competitors
Component spec may not inspire awe
Can feel overwhelmed in super aggressive terrain
Frame sizing may feel small for some riders
It’s a journeyman’s mountain bike, a tool that disappears underneath you and just gets the job done, regardless of where or how you are riding. No muss, no fuss
The FOX suspension is a real standout
Winner of our award in 2017, the Fuel EX easily impressed us with its turn of speed, capable suspension and its ability to excel on any trail.
The Fuel EX 8 is a solid trail bike offered at a reasonable price. While it wasn't necessarily the best at anything, it was really good at just about everything.

The Trek Fuel EX 9.9 is an absolute classic in the trail bike segment. Could it also be the perfect bike for the next bikepacking adventure with its modern geometry and spare parts compartment in the down tube? We put the Fuel EX to the test.
Maximum fun on the descents
Intuitive and good-natured handling
Storage compartment in the down tube for tools or snacks
Too sluggish on easy terrain
Too much bike for long straights
Chain slap

My history of mountain biking started with a little wooden trike, with no pedals and wheels bigger than my head. I moved forward as any child does onto a bigger bike with bigger wheels and pedals. My parents always encouraged me to get outside and ride a bike, although I didn’t like the idea of mountain biking. I knew how to ride a bike; why go any further?

Having spent a load of saddle time with the 2020 Trek Fuel EX 9.8 on home soil, we've been getting very familiar with this 130mm travel trail brawler. It hasn't all been smooth sailing though. Read on to see what the Fuel EX does well, what it's struggled with, and what changes we've made to our long term review rig.
Stupendously plush rear suspension
The Fox 36 has really stepped up the EX's appetite for gnar
New geometry brings masses of high-speed stability
Rattling from the downtube trapdoor
Knock Block system works but creates practical annoyances
The 35mm carbon bars are overly stiff

The Fuel EX and Tallboy are both brand new and impressively capable trail bikes, but which one do we prefer? Levy and Kazimer ride both and pick the winner.

We've been testing two 2019 130mm travel 29er trail bikes; the GT Sensor Expert and the Trek Fuel EX 9.7. Here we review the Trek Fuel EX.

Let’s be clear - Trek’s Top Fuel is a XC race weapon. This is not your typical ‘Whistler XC’ bike, which the greater industry may characterize as a ‘trail’ or ‘all mountain’ bike. The Top Fuel is designed for World Cup XC race courses. It is meant to be precise, light and fast.
