Trek Fuel+ EX 9.7 Gen 2 (2026)

Light assistance for a bike that looks to the future

More rides. More adventures. Always the same versatile trail riding feel. Fuel+ is a mid‑drive e‑MTB that provides a smooth boost without sacrificing the spirit of pedaling. With three different setup options and ultra‑adjustable geometry, you can get the perfect bike for punchy technical sections, flowy soft‑dirt lines, or sheer steep thrills. Choose adventure and let yourself be carried away.

Fit, push, repeat

Only you can define the perfect setup for your trail bike: that’s why Fuel is available in three configurations packed with adjustability. Get the versatility of the EX geometry, unleash your energy with the MX setup, or conquer any challenge with the LX version.

Adjustable leverage ratio

Want more bottom‑out resistance without losing sensitivity to small inputs? Flip the chip in the lower shock mount to achieve a more progressive leverage ratio.

Zero‑Stack integrated headset

The standard ZS headset gives you tons of options for aftermarket upgrades, including angle adjustment and anodized colors.

TQ HPR60

Compared to the past, the new Fuel+ HPR60 motor delivers higher power and torque and engages at a lower cadence, so you feel the push sooner. Plus, the 580 Wh battery gives you all the energy needed to go the distance.

New‑generation frame

Fuel+ is built around a new frame that gives you plenty of space for range extenders, long‑travel dropper posts, bigger shocks, frame bags, and more.

Active Braking Pivot

Our Active Braking Pivot technology lets suspension respond independently to braking and accelerating forces. That means more control when it matters most.
