SPECS
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 with a 750 Wh Removable Integrated Battery, a 160 mm RockShox Domain fork, 150 mm RockShox Deluxe Select+ rear shock and Bosch's latest smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), with a Bluetooth® LED remote for connectivity and activity tracking through the eBike Flow app. A 1x12 Shimano SLX/XT drivetrain, Bontrager Line dropper post, 4-piston brakes for confident descents and tubeless-ready Bontrager Line Comp 30 29er wheels.
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
The Rail Gen 4 features a pocket in the top tube, so you can easily upgrade to Bosch’s latest System Controller and Mini Remote if you’re craving a cleaner set-up
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
Bosch's smart system gives you all the same power and responsiveness with a 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
The 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
