For the mountain biker from 165 to 177 cm who wants a high-end trail e-MTB with a mechanical drivetrain, and a carbon cockpit that dampens vibration on long rocky descents.
OCLV carbon, Trek's signature. The OCLV process involves compacting the carbon layers under heat to eliminate air bubbles, a technique Trek has used since 1992. The Mountain version, specific to mountain biking, reinforces the structure against impacts. This 9.8 XT pairs that frame with a carbon handlebar, two fibre components that filter out fine vibration well.
| Carbon Fuel+ EX (9.7 to 9.9) | Aluminium Fuel+ EX 8 | Fuel EXe (previous generation) | |
| Level | Trek off-road carbon | Trek's most advanced alloy | First-generation lightweight e-MTB |
| Construction | OCLV Mountain | Hydroformed Alpha NEXT Platinum | TQ HPR50, 360 Wh battery |
| Reference bike | Fuel+ EX 9.8 XT: 20.10 kg (M) | Fuel+ EX 8: 21.08 kg (M) | Fuel EXe 9.7: 19.33 kg (M) |
| What it means | Fox Factory and XT on carbon | Heavier frame | Less torque and energy |
Put simply: the 9.8 XT is the Fuel+ EX with Fox Factory suspension and a cable-operated Shimano drivetrain. This version adds a carbon handlebar and 203 mm rotors, for 20.10 kg in M.
The ERA carbon bar filters out small vibrations better than an alloy one, and you feel less fatigue in your hands after an hour of descending through the rock gardens around Béziers. Its 800 mm width gives generous leverage; it can easily be cut down if needed.
The 203 mm rotors combined with four-piston XT M8220 calipers offer a valuable power reserve on an e-bike, which is heavier than a conventional mountain bike. The TQ assist, limited to 250 W and 25 km/h as regulations require, leaves the mechanical XT drivetrain feeling completely natural.
| Model | Frame | Motor / battery | Rear / front travel | Weight (M) |
| Fuel+ EX 9.8 Eagle 90 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 145 / 150 mm | 20.38 kg |
| Fuel+ EX 9.8 XT | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 145 / 150 mm | 20.10 kg |
| Fuel+ EX 9.8 XT Di2 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 145 / 150 mm | not disclosed |
| Fuel+ MX 9.8 XT Di2 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 150 / 160 mm | 19.79 kg |
Our take: at 20.10 kg in M, this 9.8 XT is the high-end carbon Fuel+ EX for which Trek publishes a weight. The 9.8 Eagle 90 (20.38 kg) switches to RockShox; the 9.8 XT Di2 keeps everything except the derailleur, which goes wireless.
