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, Bosch's latest tech with smart system Performance Line CX that 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 System Controller sits almost flush for a sleek look, and the Mini Remote is discreet and intuitive.
WHY YOU'LL LOVE IT
- Rail Gen 4's integrated System Controller lets you see your assist mode and battery level without getting in the way while the Mini Remote makes it easy to change modes or use Walk Assist
- Its clean cockpit is minimalist and sleek, and smart system makes it easy to add a display if you want more data
- Intelligent eMTB and Tour+ modes automatically adjust the assist based on your input to give you just the right amount of power for your ride
- The 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 to remove the battery without tools, and lets you mount a water bottle cage
