For the mountain biker who wants precise gear changes in all circumstances, even under motor power on a steep climb, and a cockpit free of the derailleur cable. It will suit the rider who likes to customise their kit and appreciates well-integrated technology.
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.

| Motor | TQ HPR60, 60 Nm | TQ HPR50, 50 Nm | Bosch Performance Line CX |

| 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 XT Di2 M8260 derailleur is controlled by radio: no more housing getting gummed up, no more adjustment drift over the rides. Shifting stays the same on day one and day one hundred, which matters on an e-MTB where the drivetrain works under the motor's torque. We carry out the pairing and shifter configuration when you collect the bike.
The TQ HPR60 motor delivers up to 350 W peak to get you going again on short steep pitches, then stops at 25 km/h, with 250 W nominal, as e-bike regulations in Europe require. On the rough climbs of the Caroux, this measured push combined with crisp shifting lets you keep your rhythm without jolts.
| 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: with identical frame, motor and suspension, the 9.8 XT Di2 differs from the 9.8 XT in its wireless derailleur. At 19.79 kg in M, it weighs 310 g less than the Fuel+ EX 9.8 XT (20.10 kg), while offering more travel.

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.

The LVR Cycles verdict The Fuel+ MX for those who want a drivetrain that is always spot on, with no cable to maintain, on a lightweight all-mountain e-MTB. The glossy smoky navy over matt black gives it a discreet elegance.
