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, 750 Wh 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. It’s 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 adjust the assist automatically based on your input to give you just the right amount of power for your ride
- The new frame is extra stout with a 34.9 mm seat tube to accommodate more robust dropper posts and an oversized head tube that works with burly e-MTB-optimised 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
