For the mountain biker who rides varied terrain, from the fast trails around Lake Salagou to the rocky slopes of the backcountry, and wants to adapt their bike to each season. It will suit the methodical rider who likes to understand and adjust their setup.
OCLV carbon, Trek's signature. Behind the OCLV acronym lies a moulding method Trek has used for more than thirty years: the carbon layers are pressed at high temperature until the air bubbles that weaken a composite are eliminated. The Mountain version of this carbon is calibrated for the impacts of mountain biking rather than for saving grams. It is what allows the Fuel+ MX 9.8 XT Di2 to carry a motor, a 580 Wh battery and a 160 mm fork for 19.79 kg in size M, with the Trek lifetime warranty on the frame.
| Fuel+ (TQ HPR60) | Fuel EXe (TQ HPR50) | Rail+ (Bosch CX) | |
| Motor | TQ HPR60, 60 Nm | TQ HPR50, 50 Nm | Bosch Performance Line CX |
| Battery capacity | 580 Wh | 360 Wh | 800 Wh |
| Published weight (M) | 19.79 kg | 19.33 kg (EXe 9.7) | 23.73 kg (Rail+ 9.7) |
| Who it is for | Riders who want an agile bike and a real reserve | Mountain bikers who put a natural feel first | Big days out and very steep slopes |
Put simply: the Fuel+ MX 9.8 XT Di2 is the only Fuel+ MX for which Trek publishes a weight, 19.79 kg in size M, which is 310 g less than the Fuel+ EX 9.8 XT quoted at 20.10 kg. It combines Fox Factory suspension, a Shimano wireless drivetrain and a 580 Wh battery on the range's all-mountain frame.
The ABP rear suspension, with its pivot concentric to the wheel axle, keeps braking independent of the shock's movement: the rear wheel stays active when you brake hard on a rough slope. Combined with the adjustable progression, it gives you a softer rear end for grip or a firmer one for landings.
The Fox 36 GRIP X2 fork and Float X shock can be finely tuned in compression and rebound. We work with you to establish a base setting suited to your riding weight with kit, then refine it after a few rides. The TQ assist, limited to 25 km/h and 250 W nominal as for any European e-bike, does not change this logic: a well set-up bike stays more precise and less tiring.
| Model | Motor / battery | Rear / front travel | Drivetrain | Weight (M) |
| Fuel+ EX 9.8 XT | TQ HPR60, 580 Wh | 145 / 150 mm | Mechanical Shimano XT | 20.10 kg |
| Fuel+ MX 9.8 XT | TQ HPR60, 580 Wh | 150 / 160 mm | Mechanical Shimano XT | not disclosed |
| Fuel+ MX 9.8 XT Di2 | TQ HPR60, 580 Wh | 150 / 160 mm | Wireless Shimano XT Di2 | 19.79 kg |
| Fuel+ MX 9.9 X0 AXS | TQ HPR60, 580 Wh | 150 / 170 mm | Wireless SRAM X0 Eagle AXS | not disclosed |
Our take: all Fuel+ MX models share this adjustable frame, and the 9.8 XT Di2 is the only one with a published weight (19.79 kg in M). The 9.9 X0 AXS moves to RockShox suspension with a 170 mm fork, while the 9.8 XT goes back to a cable-operated derailleur.

LVR sizing advice If you are hesitating between two sizes, the shorter one makes changes of direction in the woods easier, the longer one inspires confidence on fast, rough descents. Dropper travel follows frame size, from 150 to 200 mm.

| What is ABP? | A rear pivot concentric to the wheel axle that keeps the suspension active under braking. |
| Does the progression need adjusting? | The stock setting suits most riders; we adjust it for jumping or rough terrain. |
| How many adjustments on the fork? | Compression and rebound, each at high and low speed with the GRIP X2 damper. |
