How it compares

On travel, the Trek Fuel+ EX is right where the “e-MTB for trail and touring” category usually is: 150 mm up front against a median of 150 mm from 101 bikes. The fork has 5 mm more travel than the rear end with 145 mm – a common layout that takes load off the front on steep terrain. Within Trek’s e-mountain bikes, it sits between the Trek Powerfly+ FS and the Trek Rail+ on travel. Depending on the build, the frame is aluminium or carbon.

At €5,499 for the 8 Gen 2 build, pricing is typical for the category (median €5,500). For the 9.9 X0 AXS Gen 2 build, Trek asks €11,499. Depending on the build, fork and shock come from FOX and RockShox. In total, 4 different forks are used, from the FOX 36 Rhythm to the FOX 36 Factory. Drive comes from TQ HPR60, paired with 580 Wh of battery capacity.

Setup notes for this spec

Fork (FOX 36 Rhythm): air goes in through the valve on top of the left leg. After every change, compress the fork firmly a few times before measuring SAG.
Rebound: turn the red FOX and RockShox adjuster fully closed first and count clicks from there – that way you can note settings and restore them later.
Air shock (FOX Float X Performance): measure SAG in your riding position, ideally with a helper holding the bike. Cycle the shock a few times after every pressure change.
e-MTB: the extra weight mainly affects tyre pressure, which is why the table below already includes a surcharge. SAG is measured just as on a bike without a motor.

Target SAG for the Trek Fuel+ EX

Instead of percentages, this table gives SAG directly in millimetres, measurable with the O-ring on the stanchion and on the shock shaft. Change the pressure step by step until you reach the value; if Trek gives its own target SAG, use that.

150 mm fork, 60.0 mm shock stroke (all builds)

Riding style	Fork SAG	Shock SAG
XC / touring	17 % = 26 mm	24 % = 14.4 mm on the shock shaft
Trail	20 % = 30 mm	28 % = 16.8 mm on the shock shaft
Enduro / rough	22 % = 33 mm	30 % = 18.0 mm on the shock shaft
Bike park	20 % = 30 mm	27 % = 16.2 mm on the shock shaft

How to measure SAG is explained in our guide SAG setup.

Tyre pressure starting values

The values apply to 2.60″ wide tubeless tyres with a trail casing, including the e-MTB surcharge. With an inner tube add about 0.2 bar (2.9 psi), with an insert take off about 0.1 bar (1.5 psi).

Ready-to-ride weight	Front	Rear
60 kg	1.40 bar (20 psi)	1.60 bar (23 psi)
70 kg	1.52 bar (22 psi)	1.72 bar (25 psi)
80 kg	1.64 bar (24 psi)	1.84 bar (27 psi)
90 kg	1.76 bar (26 psi)	1.96 bar (28 psi)
100 kg	1.88 bar (27 psi)	2.08 bar (30 psi)
110 kg	2.00 bar (29 psi)	2.20 bar (32 psi)
120 kg	2.12 bar (31 psi)	2.32 bar (34 psi)

Air pressure in the fork and shock

You will find a suitable starting pressure on the sticker on the fork stanchion (or on the shock) or in the suspension manufacturers’ setup charts. Our calculator gives you a starting value including rebound for your weight and riding style. What matters afterwards is the measured SAG from the table above.

Note: all values without guarantee. Specification can vary by model year, frame size and market – if in doubt, the type plate, the manual and Trek’s information apply. Never exceed maximum pressures.
