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 just as cleanly as analog trail bikes. You want the light weight and responsive ride of an OCLV Mountain Carbon frame.
The tech you get
An OCLV Mountain Carbon frame that fully encases a 625Wh battery, a 160mm RockShox Yari RC fork, 150mm of rear travel with a RockShox Deluxe Select+ shock, a Bosch Performance Line CX 250W motor that assists up to 20 mph, and a Kiox controller. A 1x12 SRAM NX Eagle 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.
favorite_borderWhy you'll love it
- The new, better-than-ever Bosch motor is smaller, lighter, and more efficient. It feels more natural while you’re pedaling, and has less drag when you’re not
- Rail shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain—no shuttle or lift necessary
- The full-color Bosch Kiox display is mounted on the top tube so you can see ride data like support level, speed, battery life, and more
- 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)
- 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
- Smaller frames (S) have a top tube that dips down as it approaches the seat tube

New Bosch Performance Line CX
The all-new Bosch Performance Line CX motor is lighter, smaller, and quieter than previous versions, for cleaner integration and more nimble handling. It's also more efficient so you can go farther on a single battery charge. Use the intelligent eMTB mode to automatically adjust the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power so you can focus on enjoying the ride.
Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.
Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure—no more error codes from mis-aligned sensors.
Bosch Kiox display
Bosch Kiox's bright, full-color screen is easy to read in any light conditions and is protected by durable Gorilla Glass. You can view battery life, support level, speed, heart rate, and more. Plus, it seamlessly connects to your phone through the Bosch eBikeConnect app to share ride data, GPS map routes, altitude, cadence, and power output.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
