Product Details

It's right for you if...

  • You’re looking for a long-travel carbon e-MTB with high-performance parts. You crave the responsiveness of carbon, the plush feel of high-end suspension, and would rather get all the good stuff now than have to upgrade down the line.

The tech you get

  • An OCLV Mountain Carbon frame that fully encases a 625Wh battery, a super responsive RockShox ZEB Select+ fork with extra-burly 38mm stanchions and loads of adjustability, a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a Bosch Performance Line CX 250W motor that assists up to 20 mph, and a Kiox controller. A SRAM GX Eagle drivetrain with an extra-low 52-tooth climbing gear, downhill-rated 4-piston brakes for unflinching descents, and Bontrager Line Comp 30 29er wheels with robust SE5 Team Issue tires that come completely tubeless ready, including sealant.

The final word

  • This bike features across-the-board upgrades that make it a serious ripper—especially the suspension package. It's built for hammering gnarly descents, then flying right back up again thanks to the powerful Bosch drive system.

Why you'll love it

  • The new, better-than-ever Bosch motor is smaller, lighter, and more efficient. It feels more natural while you’re pedaling, and has less drag when you’re not
  • The full-color Kiox controller displays ride info, connects with your Bluetooth enabled devices, and has a built-in theft prevention feature
  • RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
  • Made with the same exclusive frame tech as Remedy and Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
  • 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 to remove the battery without tools and lets you mount a water bottle cage
