Trek Fuel+ EX 5 Gen 2 (2026)

Light support for a future-focused bike

More revolutions. More adventures. The same versatile ride feel on the trail. Fuel+ is a mid-assist e‑MTB designed to deliver a comfortable boost without sacrificing the essence of pedaling. With three different configuration options and ultra-adjustable geometry, you can customize the perfect bike for technical, lively sections, silky dirt flow, or thrilling gradients. Choose adventure and let yourself be carried.

Fit, push, repeat

Only you can decide the setup of your perfect trail bike—that’s why Fuel is available in three finely adjustable configurations. 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 get a more progressive leverage ratio.

Integrated Zero‑Stack headset

The standard ZS headset offers tons of aftermarket upgrade potential, including angle adjustment and anodized colors.

TQ HPR60

Compared to the past, the new Fuel+ HPR60 motor delivers higher power and torque and intervenes at a lower cadence, giving you a feeling of push earlier. Plus, the 580 Wh battery gives all the energy needed for even the longest rides.

Redesigned frame

Fuel+ is built on a new frame that provides ample space to accommodate range extenders, long dropper posts, beefier shocks, frame bags, and much more.

Active Braking Pivot

Our Active Braking Pivot technology allowed our engineers to optimize suspension performance as it reacts independently to acceleration and braking forces. This means you get safer control when you need it most.
