The Rail 9 is our top-of-the-line alloy electric mountain bike with long-travel suspension. It features a suspension set-up and parts worthy of the gnarliest enduro runs, and the powerful Bosch drive system will get you back up the mountain faster than you ever thought possible. It comes decked out with a wireless SRAM AXS drivetrain for reliable shifting and an ultra-tidy cockpit.
It's right for you if...
You’re looking for a super capable long-travel e-MTB that’s built to conquer techy runs and big drops. You want the light weight and responsive ride of an OCLV Mountain Carbon frame with a high-powered motor to get to more descents faster.
The tech you get
An OCLV Mountain Carbon frame that fully encases a 625 Wh battery, a 160 mm RockShox Domain fork, 150 mm of rear travel with a RockShox Deluxe Select+ shock and a Bosch Performance Line CX 250 W motor. A 1x12 Shimano SLX/XT drivetrain, Bontrager Line dropper post, powerful 4-piston brakes for confident descents and Bontrager Line Comp 30 29er wheels that are already completely tubeless-ready, including sealant.
The final word
Rail 9.7 hits the sweet spot of carbon performance and amazing value. It’s spec'd with quality trail-specific parts and a powerful Bosch drive system so you can send it through the rough stuff and motor right back up for another run.
Why you'll love it
- 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
- The Bosch motor gives you plenty of power for tackling steep climbs with the efficiency to keep exploring all day
- Bosch's new smart system gives you all the same power and responsiveness with a new Bluetooth-connected LED remote and eBike Flow app that puts even more control and customisation at your fingertips
- The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
- 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)
