Details

Rail 9.8 GX AXS is a long-travel carbon e-MTB that rips like our beefiest trail rigs and powers you right back up the mountain. You get upgraded everything, including the frame for maximum fun on the gnarliest runs. Bosch's latest tech with smart system Performance Line CX has a longer-range 750Wh battery and cool features that take your ride to the next level like activity tracking, navigation, and Bluetooth connectivity. The new System Controller sits almost flush for a sleek look, and Mini Remote is discreet and intuitive.

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
