For the mountain biker who often loads their bike onto a bike rack or a shuttle to reach trailheads, and who goes on mountain bike trips to the neighbouring ranges. Size L is aimed at riders from 177 to 188 cm.
Alpha NEXT Platinum aluminium, Trek's know-how. At Trek, Alpha refers to a family of alloys in several grades: Silver for entry level, Platinum above it, and NEXT Platinum at the top, the one used on this Fuel+ EX 8. The tubes are shaped to house the TQ motor and removable battery, with wall thicknesses tuned section by section. It is a frame that takes rock strikes without a second thought.
| Aluminium Fuel+ EX 8 | Carbon Fuel+ EX (9.7 to 9.9) | Fuel EXe (previous generation) | |
| Level | High-end Trek aluminium | Trek mountain bike carbon | Previous lightweight e-MTB |
| Construction | Alpha NEXT Platinum, tuned wall thickness | OCLV Mountain | Carbon, TQ HPR50 and 360 Wh |
| Reference bike | Fuel+ EX 8: 21.08 kg (M) | Fuel+ EX 9.7: 19.73 kg (M) | Fuel EXe 9.7: 19.33 kg (M) |
| What it means | Gentler budget, same motor | 1.35 kg lighter | Less torque, smaller battery |
Put simply: the Fuel+ EX 8 offers the TQ HPR60 drive system, 580 Wh battery and 145 / 150 mm of the carbon versions on an aluminium frame. It weighs 21.08 kg in M, 1.35 kg more than the carbon 9.7.
The transport protection built into the frame limits rubbing when the bike sits on a shuttle trailer or pick-up bed, a common situation when you are lapping descents around Lodève. The removable battery also makes loading easier: you take it out to lighten the bike before lifting it onto the rack.
The TQ HPR60 motor fits in a compact casing that keeps decent ground clearance over rocky steps. Its assist is capped at 25 km/h, as e-bike regulations require, which is plenty on the trails. We recommend storing the battery at between 30 and 60 % charge during long winter breaks.
| Model | Frame | Motor / battery | Rear / front travel | Weight (M) |
| Fuel+ EX 8 Eagle 70 | Alpha NEXT Platinum alloy | TQ HPR60 / 580 Wh | 145 / 150 mm | 21.08 kg |
| Fuel+ EX 9.7 Eagle 70 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 150 mm front | 19.73 kg |
| Fuel+ EX 9.8 Eagle 90 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 145 / 150 mm | 20.38 kg |
| Fuel+ MX 9.8 XT Di2 | OCLV Mountain carbon | TQ HPR60 / 580 Wh | 150 / 160 mm | 19.79 kg |
Our take: at 21.08 kg in M, the Fuel+ EX 8 is 1.35 kg heavier than the carbon 9.7. For use involving lots of transport and handling, aluminium shrugs off minor knocks, which partly makes up for the extra weight.

LVR sizing advice If you are between sizes, the shorter one makes the Fuel+ EX 8 livelier in hairpins, the longer one more stable when the terrain speeds up. The dropper post grows with the frame: 170 mm in M, 200 mm in L.
