Description

It’s right for you if…
You’re looking for a long-travel carbon e-MTB with wireless electronic shifting and a lot of battery power. You want the stability of a longer reach, the plush feel of high-end suspension, and the very latest e-bike tech with the new Bosch smart system.

The tech you get

An upgraded OCLV Mountain Carbon frame with longer reach and oversized head tube and seat tube for maximum strength. An extra-long-range 750Wh battery, a super responsive RockShox ZEB Select+ fork, and RockShox Super Deluxe Ultimate Thru Shaft shock. You get SRAM GX AXS wireless electronic shifting and the latest from Bosch with smart system Performance Line CX, including the new Bluetooth® System Controller that’s integrated into the top tube and compact Mini Remote to change modes.

The final word

This bike features across-the-board upgrades that make it a serious ripper—especially the AXS drivetrain. It’s built for hammering gnarly descents, then flying right back up again thanks to the powerful Bosch motor, 750Wh battery, and parts that can keep up with all that rowdy riding.

Why you’ll love it

The new System Controller shows your currently-selected assist level and remaining battery level. Its neatly integrated into the top tube for maximum protection and a sleek look

Bosch’s new smart system gives you all the same power and responsiveness with a new discrete Mini Remote that’s streamlined with just the controls you need at your fingertips to toggle through assist levels or change to walk mode

Intelligent eMTB and eMTB Lite modes automatically adjust the assist based on your input to give you just the right amount of power for your ride

The new frame is extra stout with a 34.9mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly e-MTB-optimized forks for less flex and more precise steering

Trek’s Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage

Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.

Bosch Performance Line CX motor
Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

Bosch Mini Remote
The compact, ergonomic Mini Remote lets you easily change assist level, activate Walk mode, or turn on optional lights, all without moving your hand off the handlebar. Plus, it’s wireless and connects with your System Controller via Bluetooth

Bosch System Controller
The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. It’s integrated into the top tube so it’s out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.

Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalized experience. Use it to customize your motor’s assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. There’s even handy features like navigation and service reminders.
