Trek Fuel+ EX 9.8 Eagle 90 Navy Smoke: top-flight suspension on a lightweight e-MTB

The Trek Fuel+ EX 9.8 Eagle 90 Gen 2 stands out for its suspension: a 150 mm RockShox Lyrik Ultimate fork with Charger 3.1 RC2 damper and a 145 mm Super Deluxe Ultimate RC2T shock, the same as on the 9.9. OCLV Mountain carbon frame, TQ HPR60 motor, 580 Wh battery and SRAM Eagle 90 drivetrain, for 20.38 kg in size M according to Trek. The Gloss Navy Smoke/Matte Trek Black dresses the frame in a smoky, glossy midnight blue set off with matt black.

Who is it for?

For the mountain biker who judges a bike first on how it descends, and wants the assist to get back up faster so they can ride down more often. It will appeal to riders who frequent technical trails without wanting the weight of an enduro e-MTB.

The LVR workshop view

OCLV carbon, Trek's signature. Behind the OCLV acronym lies a process of curing the carbon plies under high pressure to eliminate micro-voids. For mountain biking, Trek developed a Mountain version whose layup prioritises impact resistance. On this Fuel+ EX 9.8 Eagle 90, the frame features an adjustable head angle and adjustable progression, and carries a lifetime warranty.

	Carbon Fuel+ EX (9.7 to 9.9)	Aluminium Fuel+ EX 8	Fuel EXe (previous generation)
Level	Carbon reserved for mountain bikes	Premium Trek aluminium	Previous-generation lightweight e-MTB
Construction	OCLV Mountain, impact reinforcements	Alpha NEXT Platinum	OCLV Mountain, HPR50 and 360 Wh
Reference bike	Fuel+ EX 9.8 Eagle 90: 20.38 kg (M)	Fuel+ EX 8: 21.68 kg (M)	Fuel EXe 9.7: 19.33 kg (M)
What it means	High-end suspension on carbon	Heavier, cheaper	10 Nm and 220 Wh less

Put simply: the 9.8 Eagle 90 is the Fuel+ EX that puts suspension first, with the same RockShox Ultimate pairing as the 9.9, a mechanical drivetrain and alloy wheels. It weighs 20.38 kg in M according to Trek.

The Charger 3.1 RC2 damper separates high- and low-speed compression: the fork stays firm under heavy braking while still soaking up sharp hits from roots. On the slabs and steps of the Caroux, the Lyrik sits high in its travel, which preserves the geometry as the gradient steepens.

The Maxxis Minion DHF front and DHR II rear tyres, with EXO+ casings, are a descending setup that inspires confidence in the red-earth corners around Lake Salagou. The TQ motor, limited to 250 W and 25 km/h like every e-bike, fades into the background as soon as the trail points downhill.

Which Fuel+ should you choose?

Model	Frame	Motor / battery	Rear / front travel	Weight (M)
Fuel+ EX 9.7 Eagle 70	OCLV Mountain carbon	TQ HPR60 / 580 Wh	150 mm front	20.68 kg
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+ LX 9.8 Eagle 90	OCLV Mountain carbon	TQ HPR60 / 580 Wh	160 / 170 mm	20.88 kg

Our take: the 9.8 Eagle 90 (20.38 kg in M) shares its RockShox Ultimate suspension with the 9.9, with a mechanical drivetrain. If you want more travel, the Fuel+ LX 9.8 Eagle 90 steps up to 160 / 170 mm for 20.88 kg.

LVR sizing advice

Between two sizes, the smaller one makes the 9.8 more playful in tight turns, the larger one more stable at high speed. The dropper goes from 150 mm in S to 200 mm from L upwards, and the S gets a 27.5-inch rear wheel.

Size	S	M	L	XL	XXL
Rider height (cm)	155-165	165-177	177-188	188-195	195-203
Inseam (cm)	74-78	79-83	84-89	89-91	91-97
Dropper post (mm)	150	170	200	200	200
Front / rear wheels (in)	29 / 27.5	29 / 29	29 / 29	29 / 29	29 / 29

Your questions

Enough travel for enduro?	For recreational riding, yes; for full-on enduro, the Fuel+ LX offers 160 / 170 mm.
What can you adjust on the Lyrik?	Air pressure, rebound, and high- and low-speed compression.
Are the Maven Bronze brakes enough?	Yes, four pistons and 200 mm rotors, well suited to the weight of an e-MTB.
Is the blue very dark?	A smoky navy that looks almost black in the shade and blue in full sun.

The LVR Cycles verdict

The Fuel+ EX that prioritises descending, with the suspension from the 9.9 and a simple mechanical drivetrain. Its smoky navy over matt black is wonderfully understated.

Pros
+ RockShox Lyrik and Super Deluxe Ultimate
+ Maxxis Minion descending tyres
