Trek Fuel+ MX 9.8 Eagle 90 Gen 2
Trek / Electric Mountain Bikes
One bike for every kind of trail.
Fuel+ MX 9.8 Eagle 90 is a chaos-craving carbon e-MTB for chasing side hits, lap after lap. It starts off with an OCLV Mountain Carbon frame with TQ's HPR60 motor, speced with a RockShox ZEB Ultimate and RockShox Vivid Ultimate (150mm rear, 170mm front), and MX wheels for getting wild on the trail. A mechanical SRAM Eagle 90 transmission gives you reliable shifts without the fuss of electronics, and 4-piston SRAM Maven Bronze brakes deliver power you can count on.

The ride, not just the specs
Fuel is the all-around trail bike: smooth on the climbs, playful on the way down, and happy on just about any trail you point it at.

What makes it special
Only you can define your perfect trail bike — that's why Fuel+ is available in three adjustability-packed configurations. Get do-it-all capability with EX, go pop-happy with MX, or charge through it all with LX.
Want more bottom-out resistance without giving up small-bump sensitivity? Flip the chip in the lower shock mount for a more progressive leverage rate.
With a ZS standard headset, you've got tons of options for aftermarket upgrades, including angle adjust or anodized colors.
