Trek Rail 9.7 Gen 4 Full Suspension Electric Mountain Bike 2023
Rail 9.7 is a long-travel carbon electric mountain bike that gets you to the fun stuff faster. It's decked out with an upgraded frame that offers more reach for serious stability on the trail and a Bosch smart system drive unit with beefy 750 Wh battery that makes the climbs go by fast and the laps feel endless.
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 of rear travel with a RockShox Deluxe Select+ shock and the latest from Bosch with smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), including a Bluetooth® LED remote for easy connectivity and activity tracking through the eBike Flow app. 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.
Why you'll love it
- The Carbon Rail Gen 4 has the same enduro-inspired geometry and huge battery as the previous generation, but now it has a pocket in the top tube that makes Gen 4 compatible with Bosch’s integrated System Controller and Mini Remote
- 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
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.
